  7000万听障者奢望:定制“中国好声音”
发布: sharylh - 04-14-2020, 12:53 PM - 版块: 市场动态 - 无回复

“最怕去餐厅,各种说话的声音干扰很大,助听器里传出来的声音更是震得耳朵疼,特别不舒服。更糟糕的是,经常因为听不清楚对方说话乱打岔出丑,比如一次朋友说要点单,我说我不吃蛋,特别尴尬。”已经佩戴助听器十多年的刘珩(化名)告诉《第一财经日报》记者。

  清晰地听到这个世界,不再大吼大叫地和家人朋友说话,不再打岔,不再出各种尴尬状况,对生活在扬州的刘珩来说,是一个奢望。

  这是长年佩戴助听器的听力损伤患者最常遇到的状况之一,因为时常伴有沙沙的噪声干扰,听不清对方讲话或简单的外界声音放大等因素,助听器佩戴者通常会表现出高度的可辨识性——沉默、说话特别大声、打岔、沟通困难及惧怕与人沟通。

  不再“大吼大叫”

  公开数据显示,目前全球人口中,超过6.3亿人受到听力问题的困扰;按照第二次全国残疾人抽样调查数据推算,我国现有听力残疾人2780万,每年新生听力残疾儿童2.3万;此外,药物性致聋情况在我国儿童中也不在少数——即便是在全球范围来看,中国的聋哑人也是残疾人中最大的一个群体。

  但与之对应的,中国目前应对听力损伤者的市场还是一个巨大的空白——据统计,我国目前只有4所大学有听力相关专业,全国只有不到1万名听力专业人士,对听力损伤者的专业服务力量远远不够。

  另一方面,作为听障人士的生活必需品助听器,现实的状况是,其产量只能满足全球不到10%的需求。相比发达国家助听器约20%的市场渗透率,发展中国家,每40个需求者中只有不到一位拥有助听器。

  据调查,全国7000多万听障者中,70%应该佩戴助听器,即4900万人;其中10%的人验配助听器,暂按一只耳朵计算,需要490万台助听器;按每5年更新一次计算,则每年至少需要98万台。

  另一组数据进一步显示,从发现听力障碍到最后选配助听器,平均等待时间约7~10年;从关键的佩戴率上来看,国内助听器选配比例在5%左右,发达国家助听器选配比率约25%,是国内的5倍。

  “即便是对已经佩戴助听器的患者来说,最大的问题仍然是与国人听力习惯和发音的契合问题。”北京听力协会王树峰博士向记者表示。

  据了解,听力障碍是指听觉系统中的传音、感音以及对声音综合分析的各级神经中枢发生器质性或功能性异常,从而导致听力出现不同程度的减退。不同听障人群的听力损失类型有所不同,主要分为平坦型、渐降型、显降型和陡降型。我国听障人士的听力损失类型主要以平坦型听力损失为主,即各个频率的听阈几乎相等,这一比重高达53%,但相对于其他听力损失佩戴助听器后的效果是最好的。

  然而,市场上普遍应用的助听器是搭载国际通用言语即英语语音语调的数字处理器,而欧洲人以陡降型听力损失(低频区听力接近正常,到1000Hz以上的频率区陡降)为主,中文有独特的四声声调相较于英文更低沉饱满,现实生活中中国的生活环境噪音也较高,这就决定了在国外可能用得不错的助听器在中国患者身上的体验并不好。

  中文定制

  “全球市场来看,助听器目前的研发企业都是国外公司,但国外和中国可能在环境上最大的差别就是,中国非常热闹。”瑞士Sonova索诺瓦听力集团旗下峰力公司培训部总监,高级听力学家杨欣怡博士向记者介绍,“比如在瑞士,大家说话都很小声,餐厅也很安静,助听器佩戴者并不会对助听器中被放大的噪声特别敏感。”

  杨欣怡和她的研发团队优化了大声放大水平、压缩速度、低频声音及轻度到中度听力损失的高频压缩,提出了适应中文言语的听力解决方案。

  “我们发现,中国人不仅热情好客,对于‘讲中文’的助听器也有非常积极的建议。”她说。

  她告诉记者,他们根据中国街道等公共场所噪声水平,对中国定制产品进行了噪声级别针对性的设置,添加了噪声净化功能“噪声防护盾”。

  北京市耳鼻喉科研究所在随后盲选临床试验的结果显示,无论在安静还是嘈杂环境中,搭载中文言语处理的助听器都能显著提升用户的中文言语理解力。

  在安静环境中,中文言语理解率显著提升,平均提高41%;在嘈杂环境中,中文言语理解率显著提升,平均提高40%;在非常嘈杂的环境中,中文言语理解率也有显著提升,平均提高23%。同时,搭载中文言语处理器的助听器获得了中文用户更高的验配偏好度,67%的用户更偏好中文言语处理器。

  在首批试用的患者反馈中,可以听到以往根本听不到的孩子低语,不再大吼大叫地对家人说话,再也不用忍受持续的沙沙沙噪音等感受成为中文平台助听器与普通助听器的最直观感受。

  “站在马路边,我再也不用忍受轰隆隆的车队般的轰鸣声了,我可以清晰地听得到,车是一辆一辆地从身边开过去,觉得世界都不再那么吵了。”北京的刘女士告诉记者。

  而对峰力听力来说,中文平台不仅打开了中国听力设备的广阔市场,甚至在印度也收到了意外之喜。

  “作为另一大古老文明,印度语音中也有类似中文声调的部分,我们没有想到的是,为中国患者开发的处理平台在印度也很受欢迎。”杨欣怡告诉记者。

  “中国市场潜力巨大,我们非常期待未来5~10年在中国市场的快速增长。”SONOVA集团CEOLukasBraunschweiler接受《第一财经日报》采访时透露,“事实上,我们仍然在中国加速开发符合中国客户需求和使用习惯的新产品。”

  卜行宽教授分享《成人助听器行业国际现状及我国发展的机遇和挑战》(上篇)
发布: sharylh - 04-14-2020, 12:21 PM - 版块: 市场动态 - 无回复

2019年12月23日,江苏金陵职业技术学校二十一周年的庆典活动在中国南京盛大举行。世界卫生组织(WHO)总部防聋专家卜行宽教授出席了本次会议,并在会上作了《成人助听器行业国际现状及我国发展的机遇和挑战》的主题发言。卜教授主要分享了听力损失的特点、助听器概述,重点介绍了成人助听器行业国际现状,并探讨了我国在该领域发展的机遇和挑战,最后卜教授呼吁“让我们为实现世卫和我们的共同愿景而努力”!

专家介绍

[图: 15773244461caf20d0rG.jpg]
卜行宽,现任江苏省耳科疾病与听力障碍诊治中心主任、国际耳鼻咽喉科协会联盟(IFOS)/ 国际听力学协会(ISA)江苏耳科与听力中心主任、听力国际(Hearing International)副主席、世界卫生组织(WHO)总部全球防聋专家、WHO预防聋和听力减退合作中心主任。  江苏省人民医院(南京医科大学第一附属医院)耳鼻咽喉科主任医师、教授。多年从事耳科疾病与听力损失的防治工作,4次荣获省部级科技进步奖,享受国务院特殊津贴,获江苏省和全国“优秀科技工作者”荣誉称号。
一、听力损失的特点
[图: 157732453014g9IROFLH.jpg]
听力损失的特点,我把它总结为“三高一低”:高流行、高影响、高干预、低认知
高流行
按照世界卫生组织去年最新资料的评估,全世界人口的6.1%达到听力残疾的程度,注意不是一般的听力损失,而是听力残疾。听力残疾怎么定?人是两个耳朵,是相对好的耳朵来算,而不是坏的耳朵算。换句话讲,假如我1个耳朵全聋,1个耳朵听力还在正常范围,这样是不算听力残疾的。相对好的耳朵,平均的听力损失(4个频率)超过40分贝,这个就是听力残疾。全世界这样的人有4.66亿,占人口的6.1%。换句话讲,全世界每100个人当中就有6个人是听力残疾的,这是一个非常大的数量。
根据中国最新的资料,2015年世界卫生组织的标准来算,中国有听力残疾人7000万,这个7000万是相对好的耳朵算出来的数据,按差的耳朵会更多。所以这7000万的人实际都需要助听器的帮助, 因此助听器的需求量从理论上推算是7000万*2(台)。更加注意了,65岁以上的老人,三分之一是听力残疾。中国,乃至全世界都进入到老龄化了。比方说,江苏省65岁的老人已经超过1000万,最近的资料是1200万左右。因此江苏省65岁以上老人,听力达到残疾的人接近400万,需要助听器800万台。这样一个数据说明(听力残疾)的高度流行。
高影响
听力残疾不光影响个人、家庭,对国家、社会都造成了沉重的负担。全球经济每年要对未处理的听力问题付出7500亿国际美元的高昂代价。相当于荷兰一个国家的一年的国民生产总值,相当于中国和巴西两个国家一年的所有卫生投入总和,所以这是沉重的负担。老龄社会,老年痴呆的发病率很高,现在已经肯定,听力损失是老年性痴呆的独立高危因素,而且是唯一的也许通过及时干预可以逆转或者推迟痴呆的发生,所以这个很重要。
高干预
既然是高度流行,高度影响,我们是否有办法呢?有办法,有高度的可以干预性。世界卫生组织肯定至少有一半的听力损失完全可以预防。至于另外一半无法预防已经发生的,通过早期筛查,早期诊断,早期干预,绝大部分都是可以回归到主流社会当中来,而且可以通过各种康复的手段,使他们发挥最大的潜能。
低认知
认知度低,普遍忽视听力损失。听力损失是看不见的残疾,假如是盲人,很容易引起社会的同情,但如果是聋人,表面看不出来,所以普遍被忽视。
二、听力损失分类、原因和处理原则
[图: 1577324785uRAMpu0Esv.jpg]
耳朵分为外耳、中耳、内耳三大部分。外耳和中耳的功能最主要是声波传导的功能。内耳接收声音信号转换成电信号,然后传到大脑中枢,听觉中枢产生听觉。问题发生在外耳和中耳的,是声波传导性的听力损失,叫传音性(传导性)听力损失。这种情况大多数可以通过耳科医生的医学干预来解决。内耳的问题,属于感音神经性的听力损失。到现在为止,除了突发性听力损失,或者是自身免疫性听力损失,通过及时治疗、诊断有希望得到恢复,其他的听力损失,一般是没有办法、不可逆的,需要我们通过助听器或人工耳蜗康复处理。尽管现在研究转基因治疗,干细胞,毛细胞再生等,但临床应用还是有距离。
三、助听器概述-定义、结构、外形和验配
[图: 1577324934YCIRBs43E5.jpg]
听力康复主要的工具是助听器,助听器解决不了的极重度听力损失靠人工耳蜗。助听器是根据患者不同听力损失进行补偿的高级电声放大装置。通过麦克风把声音传进去,进入到放大器,通过调节控制、电源驱动把声信号变成电信号,放大的电信号通过受话器,把电信号转化为放大的声信号进入到耳朵。不管什么样的助听器,基本的结构原理都是这样的。助听器形式有很多种,根据外形分有:盒式、耳背式、耳内式、耳道式、全耳道式、骨导助听器。助听器需要有规范的验配程序,一般分为8道程序:耳科就诊和听力评估-咨询助听器中心-助听器预选-取耳样、制作耳模-助听器验配-效果评估-使用、维护和康复指导-随访。

  助听器行业的新趋势
发布: sharylh - 04-14-2020, 12:12 PM - 版块: 市场动态 - 无回复

者按:助听器行业正处于一场深度变革的前夜。人工智能技术显著提高了助听器的用户体验,柜台式销售(OTC)的助听器即将上市,耳机、智能终端企业正跃跃欲试地要杀入这片技术的蓝海。听力学家和助听器公司应该主动迎接助听器行业新纪元的开始。中国听力医学发展基金会设立了助听器专家委员会,并于2019年5月11日在厦门举行了成立仪式暨助听器前沿技术与未来趋势研讨会。享有世界声誉的华人听觉科学家曾凡钢教授2017年底为《听力杂志》撰写的述评,很好地反映了世界范畴内的助听器发展趋势。在征得曾教授同意后,我将其翻译成中文并在此公众号中发表,以飧读者。
[图: v2-2a7b3dd19064b182d4097e8fd235cd65_720w.jpg]ANew Landscape for Hearing AidsTheHearing Journal: 2017 - V70 (12) 6-,Zeng, Fan-Gang, Editorial 郗昕翻译
2017年标志着助听器行业新纪元的开始。在这一年里,美国FDA批准通过了助听器可以作为非处方设备品(Over-The-Counter, OTC)在柜台销售。同时,人工智能技术上的突破也为噪声环境下助听状况的改善带来了新的希望。
OTC助听器旨在为数以万计的中轻度听力损失患者提供一个安全有效的解决方法,这些听力损失患者本可以受益于助听器,却因为高昂的费用或验配的不便而放弃使用助听器。毋庸置疑的是,OTC助听器和市面上的耳机、耳塞和个人放大系统一样安全可靠。随着OTC助听器核心技术的不断提高,无论是从麦克风、扬声器,还是数字信号处理芯片以及降噪算法都已与目前最先进的助听器技术相差无几,因此人们对OTC助听器质量问题的担忧也在逐渐降低。
[图: v2-7238d6cae9ccd4ad6e64e58b2ce53611_720w.jpg]
科学研究在不断证实着OTC类助听器的有效性,美国印第安纳大学Humes 教授2017年发表的文章采用严谨的实验设计,尽可能地排除了人为因素的干扰,得出突破传统观念但又令人信服的结论——OTC助听器产生的效果与有资质的听力学家验配的高端设备所产生的效果相似。
但诚如助听器行业专家正热烈讨论的一样,有很多重要的问题还亟待解决。如食品药品监督管理局(FDA)该如何规划管理这些OTC设备,听力学家该怎样将这些设备纳入他们的服务体系中。OTC助听器能否打入现有的市场,提高市场渗透率,我们将拭目以待。
[图: v2-09b23559c2d21058892f303134579071_720w.jpg]
笔者2017年4月造访美国印第安纳大学时在Prof. Larry Humes办公室中合影,并与其讨论他刚刚发表的有关OTC助听器验配的文章HumesL, Rogers S, Quigley T, Main A, Kinney D, and Herring C. (2017). Theeffects of service-delivery model and purchase price on hearing-aid outcomes inolder adults: a randomized double-blind placebo-controlled clinicaltrial. American Journal of Audiology, Vol. 26, 53-79。
人工智能技术上的突破显著提高了助听器使用者在噪声环境下的言语识别能力。源于大脑回路的深度学习(deep learning)已经成功地被用于自动驾驶汽车上,并且打败了人类最优秀的围棋选手。在言语噪声环境下单凭一只麦克风,深度学习便可以将单词识别率从29%提高到84%,这一水平与正常听力的个体在相同环境下的单词识别率不相上下。
虽然由于功率和实时的限制,深度学习的算法还没有应用于助听器中,但却为解决听障人群的头号难题带来了希望。深度学习和其他人工智能技术,如虚拟现实和增强现实技术,可以提高并丰富听障人群乃至听力正常人群的聆听感受。一个智能的助听器将提供一个个性化的、身临其境般的交互听觉体验,如声景分析、声音防护和警告、模拟迪士尼大厅中最好的位置,甚至实时的语言翻译。广泛应用这种智能设备最大的好处,是消除了人们佩戴助听器时长期忍受的困扰。
[图: v2-fb60e311b058c788837d56537662a2c5_720w.jpg]
听力学家和助听器公司应该主动接受这些变化,因为这代表了新纪元里机遇的到来。这些机遇才是行业内游戏规则的改变者,就像电助听器和数字助听器的诞生一样。在未来的十年中,我们将看到听力学家们所关注的不仅是听障人群和正常听力的人群,甚至还可能是第一个一百亿美元助听器公司。

  耳机变身助听器的时代即将来临:FDA 刚刚通过了第一款用户自设定助听器,BOSE 拔得头筹,下一个是苹果?
发布: sharylh - 04-12-2020, 02:57 AM - 版块: 市场动态 - 无回复

美国食品和药物管理局(FDA)日前通过了第一款用户可自行设定以符合需求(self-fitting)的助听器,允许用户在没有医疗服务提供商的帮助下,可以自行安装、编程和控制的助听器。这款率先抢下 FDA 新型医疗器材(De Novo)首个上市许可的 self-fitting 助听器正是“Bose 助听器(Bose Hearing Aid)”,为知名声学大厂 Bose 所开发,旨在为 18 岁以上、患有听觉轻度至中度听力损伤的人,提供声音放大的功能。

为什么一款助听器会引起行业关注,这得从 2017 年 8 月美国通过的一项新法谈起,当时 FDA 为中度至轻度听力受损的人新增加一项“非处方”、也就是可临柜购买(OTC,Over-The-Counter)的可穿戴听力设备类别。目前 FDA 正在规划 OTC 助听器的规章制度。
虽然 Bose 助听器还不是归属在OTC 助听器类别下,因为根据 FDA 官方公开的资料并未使用OTC 这个词汇,但 Bose 助听器在意义上已经非常接近 OTC 助听器,因为以往要购买助听器,得先经过医生或听力医疗机构的检查、测试、接着调校助听器的声音,但未来产品上市,消费者可以自行设定并调整功能。
特别是,试图把耳机变成助听器的公司其实不少,苹果、谷歌等都有类似产品开发计划,其他的还有 Nuheara 在今年推出了旨在提高听力的耳机。另外,还有已经宣布关门解散的初创公司Doppler Labs 也曾开发主动聆听(Active Listening)的耳机,识别环境场合,进而增强现实环境的声音。这类产品过去是定位为个人声音放大产品(PSAP,Personal Sound Amplification Product),而不是助听器。不过,有了 Bose 助听器拿下 FDA 第一个上市许可的案例之后,代表其他业者也可以有机会取得 FDA 的许可,势必将加速其他业者的开发脚步,后续将有更多类似产品问世,更可以预期耳机变身助听器的大门即将被打开。对传统耳机或声学公司,以及从医疗器械出发的传统助听器公司,两派人马的竞争可能会变得激烈。

手机 APP 调整助听器功能
Bose 递交给 FDA 125 名患者的临床研究数据,指出 Bose 助听器在放大音量的控制、在嘈杂环境、整体效益上,可以达到和传统助听器相当的效果。在硬件设计上,Bose 助听器为气传导式(air conduction)无线助听器。气传导式助听器是通过捕获一个或多个麦克风的声音振动来运作,并通过放置在耳道中的无线耳机来处理、放大、播放这些音讯信号。
此外,用户可以通过手机上的 APP 来调整助听器。基于这些科技,用户就能实时调整助听器,无需医疗专业人员的帮助,不过 Bose 必须尽到明确告知消费者在什么情况下应该谘询听力保健专业人员的义务。
“随着人年龄的增长,听力损失是一个重要的公共卫生问题,”FDA 设备和放射健康中心的眼科及耳鼻喉科器械部主任 Malvina Eydelman 说。他也指出,FDA 致力于确保听力损失患者可以有更多的选择方案,此项获得新上市的助听器可让患者直接操作设备的功能。
FDA 指出,在美国约有 3750 万名、18 岁以上的成年人在没有助听器的情况下会出现听力问题,程度从“有点麻烦”(听不清楚)到耳聋。听力损失是由于老化、暴露在高噪音下,或是由疾病等因素所造成。另外,听力损失可能是永久性或暂时性,对于有永久性听力损失的患者可使用助听器帮助他们更好地听到周围的声音并与他人沟通。

图|Bose 先前也曾推出可放大声音的耳机,此图片并非此次通过许可的助听器。(图片来源:Bose 官网)
下一个是苹果?
比起一直主攻在高端音响、耳机市场的 Bose 来说,外界可能更关心苹果的动态。
苹果在 2016 年底推出了AirPods 无线耳机,算是销售不错的产品,但对苹果来说,着眼的不只是音乐或是连接语音助理 Siri,苹果在今年开发者大会 WWDC 上释出 iOS 12 测试版,用户启用实时聆听(Live Listen)辅助听力功能后,iPhone 就变为一个指向性麦克风,通过放大声音,让 AirPods 变成某种程度的听力辅助器。
苹果在医疗领域的布局一直相当用心,除了甫问世的 Apple Watch 4 增加量测心电图(ECG)功能之外,耳机被视为是最贴近人体、且用户体验不突兀的穿戴式装置,因此许多厂商都试图希望把这项老产品赋予新生命,像是去年可以看到加入人工智能等技术后,耳机能够实时翻译,而随着 FDA 对于新型医疗器械的支持,耳机很快就能变身为 OTC 助听器。
按照 FDA 的进程规划,将在 2020 年 8 月 18 日之前提出新的法规来规范新的 OTC 助听器类别,接下来将进入公众意见征询期,将吸引行业及专业人士关注及提出意见,当在评估结束后,FDA 有 180 天时间发布新规定。

  疫情期间远程验配的助听器-by David Copithorne
发布: sharylh - 04-09-2020, 08:28 AM - 版块: 市场动态 - 无回复

“Telehealth,” “telemedicine,” and “telecare” are terms we will hear a lot more of during an extended period of sheltering at home. So if you wear a pair of brand-name hearing aids, now is a good time to learn about teleaudiology.”
Even before the coronavirus pandemic, hearing aid manufacturers were ramping up their remote care capabilities. Smartphone apps, text messaging, and web-based video calls were making it possible for audiologists to communicate more easily with patients at home. And new cloud-based digital services were starting to enable providers to send program adjustments directly to their patients’ hearing aids over the web.
But for many consumers and audiologists, teleaudiology is still a relatively new concept, and at-home hearing aid services have only just started to catch on. So, we can expect that necessity will be the mother of invention as patients and providers stuck at home start to use new teleaudiology tools.

Table of contents

What is teleaudiology?
In a nutshell, teleaudiology is the provision of audiological services over the phone or internet. Teleaudiology—sometimes called “remote care” or “remote hearing care”—enables your audiologist to make adjustments to your hearing aids remotely, without requiring an office visit. Web-based technologies connect an app on your smartphone to a secure online patient portal on your provider’s computer. During a virtual consultation, audiologists are able to check in on your progress, provide counseling, and make real-time hearing aid adjustments.
Remote hearing care is very helpful for those who have just been fitted with new hearing aids. It can take a lot of time—and sometimes several rounds of sound adjustments—to get fully accustomed to a new pair of hearing aids. This is especially true for first-time hearing aid wearers. Remote care makes it possible to get all the sound tweaking you need without the hassle of repeatedly scheduling and traveling to in-office appointments.
How to access remote care
In 2020, remote care is almost always provided through your hearing aids’ smartphone app. The first step is downloading the app that works with your hearing aids and granting your audiologist permission to provide you with remote assistance. Don’t worry, it’s easier than it sounds, and your audiologist will walk you through everything in their office (keep reading for the social-distancing approach) before sending you on your way. And once the app is set up, you can use it to communicate with your provider, share information about your hearing aid usage, and receive real-time adjustments to your hearing aid settings.
If you want the benefits of remote care, be sure to ask your provider about it. Does their practice offer it? Which hearing aid models are available with teleaudiology? Will you need a particular brand of phone to access remote care (most likely, either an Apple iPhone or iPad that uses the iOS operating system, or a Samsung Galaxy or other smartphone that uses the Android operating system)?
Accessing remote care during COVID-19
If you’re wearing teleaudiology-capable hearing aids, and have a compatible Android or iOS device, you may already have access to remote care. Check in with your audiologist to see if they are currently providing remote care services. If so, your audiologist will let you know if there are any additional steps necessary to access remote care.
If your audiologist is not offering remote care services, you’ll need to find help elsewhere. Check our provider directory for local clinics offering remote care. Once you’ve found a clinic to take care of you, you’ll need to (unfortunately) drop your hearing aids off at the new provider to have them enroll you in the remote care platform that supports your brand of hearing aids. Check with the new provider to see if they are accepting curbside or drop-off servicing requests.

The benefits of remote care
If you live far away from your audiologist, the cost and time savings provided by remote hearing aid care are obvious. The same is true for those who have limited mobility or who are sheltering in place due to COVID-19. Aside from the obvious benefits, there are many additional benefits of teleaudiology, including:
  • Hearing aid updates on the fly - Sound and programming updates offered by your audiologist can lead to major improvements in performance over the long term. And because immediate updates can be tested on-the-spot, you can get the best hearing aid performance possible in the listening environments that you find most challenging.
  • More interaction with your audiologist - With remote care, your provider is only a text or video call away. Any problems that come up can be solved more quickly than waiting for a time-consuming office appointment. And more interaction with your provider means you can make constant improvements that will dramatically increase your satisfaction with your hearing aids.
  • Ongoing performance monitoring - Your audiologist will have immediate insight into your hearing aid usage and performance. This will help guide the care they provide, the adjustments they make, and the recommendations they make for follow up appointments.
[size=undefined]
The net of all these benefits is better day-to-day hearing aid performance, higher satisfaction, and less time investment.
The limitations of remote care
Of course, there are limits to current remote hearing care services. You still need to visit your provider for the initial hearing test and hearing aid fitting, as well any necessary adjustments to the physical fit of your hearing aids. And real-ear measurement (REM)*, an important test that verifies your hearing aids are meeting your unique sound prescription, must still be done on site.
Additionally, not all hearing aids work with teleaudiology services. You’ll need to purchase a newer pair of Bluetooth-enabled hearing aids from one of the top-tier brands. And you’ll need to own a relatively modern iPhone or Android smartphone too. Oh, and owning the right hearing aids and a compatible phone doesn’t guarantee you access to remote care. Your audiologist needs to be trained up and technologically able to provide the service in the first place.
*Whenever possible, do not forego a REM test. If a REM test is not possible due to COVID-19 restrictions, consider asking for a refund / exchange policy that covers you if your hearing aids are not capable of meeting your prescription when a REM test is able to be performed. This will ensure you don’t get stuck with hearing aids that don’t meet your hearing needs. If your hearing aids don’t meet your REM prescription, consider asking for stronger speakers, custom earmolds, or a more powerful model. If adjustments can’t be made to give you the volume you need, consider asking for an exchange or refund.
The cost of remote care
Most audiologists bundle the cost of their services in with the cost of the hearing aids. This means, when you purchase a pair of hearing aids, you’ll usually get anywhere between 1-5 years of unlimited free follow-up service, all depending on the provider of course. The bundled price typically covers in-office visits, and with the advent of teleaudiology, bundled pricing typically includes remote follow-up visits too. However, in 2020, there is a growing trend for practices to unbundle their hearing aid pricing, so if your purchase is unbundled, be sure to check on the cost of in-office versus remote follow-up appointments. Who knows, you might even save some money by going with remote appointments.
Current teleaudiology platforms
Makers of premium hearing aids have led the development of web-based remote hearing care services. Five global manufacturers—Sonova, Demant, WS Audiology, Starkey, and GN Hearing—now control more than 80% of the global market for premium hearing aids, and all have developed remote care offerings for one or more of their product lines. Because most hearing aids are sold by audiologists, teleaudiology solutions are designed to optimize personal interaction between audiologists and patients.

Our brand comparison is a live document, and will be updated as we learn more, and as manufacturers update their solutions, so please bookmark this page.[/size]

ReSound and Beltone remote care
As people began sheltering at home due to COVID-19, ReSound and Beltone (both GN Hearing brands) both released improvements to their respective remote care platforms. Both brands already offered solutions that let people request and receive adjustments to their hearing aids remotely, but the recent update means it’s now possible to have video calls with your provider, and both brands now support real-time hearing aid adjustments.

[图: assist.jpg]
With ReSound Live Assist and Beltone Remote Care Live, you are able to have a video call with your provider and receive real-time hearing aid updates from home.
GN’s platform also allows audiologists to monitor their patients’ hearing aid usage and performance in different listening environments. This type of data helps inform counseling and future hearing aid adjustments, which ultimately leads to greater patient satisfaction.
The apps from ReSound and Beltone let you request a video call from your audiologist. During a video call, your provider can adjust your audio and program settings in real time, just like they might if you were sitting in their office. You can evaluate any new settings during the video call and have your provider make further adjustments until you’re happy with the changes. Afterwards, you’ll have a chance to try out any new settings and provide feedback through the app. Feedback you provide will help inform your audiologist on the success of the remote appointment.
Beltone’s remote assistance feature, Remote Care Live, comes with its Beltone HearMax smartphone app for iOS and works with Beltone Amaze hearing aids. In its announcement, Beltone noted the pressing need for all kinds of telehealth services:

Monte Dillow, President, Beltone 提到:Remote Care Live becomes even more important as patient access to in-person hearing care is limited as communities across the country implement various “stay home” policies to help minimize COVID-19 spread. We’ve seen the growth of telemedicine in many medical settings, but it has been a recent introduction to hearing care. With Beltone Remote Care Live, we really take it to a new level, making it easier on our patients and their families to access the hearing care they need.
At the same time, ReSound introduced its new ReSound Assist Live feature, enabling live video consultations with hearing care professionals for support wherever you are. ReSound’s wireless Bluetooth hearing aids, including ReSound LiNX Quattro and ReSound Enzo Q models, work with the ReSound Smart 3D smartphone app (iOS only for now) for adjustments to your hearing aids during live video consultations.
Phonak remote care
Phonak is the flagship hearing aid brand from Sonova Group, the world’s largest hearing aid manufacturer. Phonak currently offers teleaudiology solutions for Audeó B Direct, Audeó MBolero M, Naída M, and Virto M hearing aids. The myPhonak app lets you have a video call with your audiologist, who can make real-time adjustments to your hearing aids.

[图: maxresdefault.jpg%201280w]
Dr. Cliff, AuD, demonstrates the myPhonak app, performing a video consultation and making program adjustments from his office in Phoenix for a patient in New Hampshire. Closed captions are available on this video. If you are using a mobile phone, please enable captions by clicking on the three small dots.

The myPhonak app also has a Hearing Diary feature. The Hearing Diary logs all your hearing aid usage, so your audiologist can review how, where, and when you use your different audio settings. It also lets you share your experiences and satisfaction ratings with your provider, who can use the information to quickly and easily provide program updates.
In a survey of remote-care patients, Phonak found that 92% would recommend virtual office appointments to others who wear hearing aids, with 64% of patients indicating they prefer remote visits over face-to-face sessions. Remote care gets high marks from hearing care professionals, too, with 80% indicating that they found remote sessions as efficient as in-person appointments.
Widex Remote Care
Widex is a premiere hearing aid brand manufactured by WS Audiology. Widex Remote Care works with BEYOND, EVOKE and the soon-to-be-launched MOMENT hearing aids, as well as many legacy products. With the Widex Remote Care App and Widex Remote Link neckworn-accessory, you can have a live video call with your audiologist and receive real-time hearing aid adjustments.

[图: widex-remote-care.jpg]
Your provider can send hearing aid program updates to the Widex Remote Care App, which transmits them—in real-time—to the hearing aids through the neck-worn Widex Remote Link accessory.
Signia remote care
Signia is WS Audiology’s other premiere hearing aid brand. Signia TeleCare services are delivered through the Signia App, which has all the features needed to make modern remote care possible:
  • Remote Tuning - Enables your provider to make real-time program changes to your hearing aids through the Signia App, and to communicate face-to-face in virtual video sessions.
  • CareChat - Secure text messaging with your provider is also supported by the Signia App.
  • Daily Satisfaction Ratings - Daily reminders to rate the performance of your hearing aids and provide comments.
  • Hearing Lessons - Assess your experiences in different listening situations, and provide feedback so your provider can make the best adjustments for you.
[size=undefined]
Like Beltone, Signia has emphasized the importance of remote hearing health care during the pandemic lockdown: “At a time when reducing the spread of the coronavirus is on many people’s minds, remote assistance for hearing aids is essential. TeleCare offers remote assistance and supports you from the first appointment all the way through aftercare.”
Signia currently offers video calls and live remote tuning for most Xperience and Nx models. Other Signia models may still be tuned remotely, but without video teleconferencing, and with fewer programming options for the audiologist.
Starkey remote care
Starkey’s Hearing Care Anywhere program enables its popular Livio, Livio Edge, and Livio AI hearing aids to be programmed remotely through the Thrive Hearing Control app. You can use the app to submit a request for hearing aid updates from your provider, who is then able to send program updates, which may be downloaded and applied to your hearing aids.
When submitting a request, the Thrive app asks you to first verify that the hearing aids are clean and fitting correctly. The app then runs an automated diagnostic hardware check to ensure the hearing aids are functioning properly. You are then asked to describe the issue, after which you may submit your request.
When your provider sends you program updates, you may preview the updates before loading them permanently into your hearing aids. The Thrive app even lets you toggle back and forth between the existing and new settings, which makes it easier to select your preferred setting. After saving new settings to your hearing aids, the Thrive app asks you to rate your satisfaction with the changes.
Oticon remote care
Oticon’s RemoteCare App works with Oticon Opn S as well as the brand’s other Bluetooth-capable hearing aids. RemoteCare enables you to schedule an appointment and have a video call, audio call, or text-messaging session with your provider. Your provider can make real-time adjustments to your hearing aids while in a remote session. And your provider can adjust the settings as many times as you want during your virtual appointment. The Oticon RemoteCare App works with both iPhones and Android smartphones.
RemoteCare was available first outside the US, but was launched here on March 25, 2020. If you wear Oticon Opn S hearing aids, be sure to check with your provider to see if RemoteCare is something they are set up to offer.
Remote care for Costco hearing aids
Many people save money on brand-name hearing aids by getting their hearing tests and hearing aids from Costco. Unfortunately, Costco does not currently offer remote hearing care services. However, because many of its hearing aids are manufactured by established hearing aid manufacturers who offer remote care for hearing aids sold by audiologists, Costco may potentially offer remote care in the future, especially if periods of sheltering at home are extended.
Remote care for hearing aids you buy online
If you buy your hearing aids online from a web-based provider rather than from an audiologist, you may also receive teleaudiology services. Most online providers sell pre-programmed hearing aids, sometimes with several settings offering varying degrees of amplification. Others offer “self-fitting” models that you set up yourself using a smartphone app. Online hearing aids are often less costly than the premium models fitted by audiologists, but lacking the in-office hearing test, initial face-to-face consultation, and REM testing, it’s more of a crap shoot.[/size]

  助听器的技术春天的到来--LE Audio
发布: sharylh - 04-09-2020, 08:23 AM - 版块: 市场动态 - 无回复

What is LE Audio and LC3, the latest in Bluetooth audio?

Bluetooth SIG announced a wave of new Bluetooth audio technologies as part of LE Audio, including an improved LC3 codec.


For audio enthusiasts, the big story of CES 2020 is clearly Bluetooth SIG announcing a wave of new supported audio technologies. Built into the core Bluetooth Low Energy (LE) standard, these new features fall under the LE Audio name. Next-gen Bluetooth audio gear gains a lot of very useful features that should be much more widely supported than third party equivalents.





Headline-grabbing features of the new LE Audio standard include the new LC3 Bluetooth codec, which sounds superior to the current default SBC codec. There’s also now native support for true wireless earbuds and Bluetooth features for hearing aids too.



Here’s everything that you need to know about Bluetooth LE Audio and all its features.



Editor’s note: this article was updated on March 5, 2020 to include information on the difference between audio and file compression.



Bluetooth LE and LE Audio



Before diving into the audio side, a bit of Bluetooth background is required. Currently, there are two major forks of Bluetooth radio operation – Bluetooth Classic and Bluetooth LE. Low Energy caters for low power, low bandwidth data transfers between IoT-like devices like fitness trackers. It launched as part of Bluetooth 4.0 and remains under the Bluetooth 5.0 and 5.1 standards.



Bluetooth Classic, which includes older Bluetooth 1.0, 2.0, and 3.0 use cases, is still required for more power-hungry high-speed data transfers. This includes as sending audio data between your phone and headphones. All of the current Bluetooth audio codecs, whether that’s default SBC, Qualcomm’s aptX, or Sony’s LDAC, transmit data over Bluetooth Classic.



LE Audio changes the game, finally enabling audio data to transmit over the lower power and lower bandwidth Bluetooth LE radio too. That’s obviously great for both headphones and handset battery life and listening times. However, LE Audio will first be supported in version 5.2 of the Bluetooth Core Specification. Meaning you’ll need new devices to take advantage of it.



Check out the video below for more details on LE Audio and its components.

Meet the LC3 Bluetooth codec



LE Audio introduces an all-new Bluetooth audio codec called LC3 (Low Complexity Communication Codec).  A codec compresses audio for transmission over the air. If you need to brush up on what a codec is, check out our breakdown here. LC3 scales down to very low bit-rates while retaining good sounding audio quality. This ensures data correctly sends over the limited bandwidth of Bluetooth LE even in congested radio conditions.



For example, LC3 scales from 345kbps right down to 160kbps. SBC, Bluetooth Classic’s mandatory codec, ranges from 345kbps to 240kbps—ut it takes a substantial hit to audio quality as a result. aptX Adaptive runs between 279 and 420kbps, while LDAC ranges from 330 to 990kbps. LC3 is by far the most compact Bluetooth codec used in consumer audio to date. But what effect does that have on audio quality?



[图: Bluetooth-LC3-Codec-Comparison.jpg]LC3 scores higher for sound quality than SBC and also runs at lower bit-rates.



According to Bluetooth SIG, LC3 sounds much better than SBC even when running at lower bit-rates. The company presents the above graph, showing an industry-standard perception score for sound quality at different bit-rates.



You can read about the ITU-R BS.1116-3 perception test here if you would like to know more about how that score works. The key thing to note is that a score of 5.0 is imperceptible from the source. 4.0 indicates a perceptible but acceptable quality difference, and a score of 3.0 is “slightly annoying” in terms of quality degradation. As you can see, LC3 hovers around 4.5 even at its lowest quality setting, which is much better than SBC performs at much higher bit-rates.



The scalable nature of the LC3 codec matches the ideas we’ve seen from aptX Adaptive and LDAC. Quality dials back when connection quality becomes an issue, such as when listening at long distances or in congested radio environments. The move to the limited bandwidth of Bluetooth LE makes this a necessity. It will be interesting to see how regularly LC3 defaults to higher quality bit-rates.



LC3 changes Bluetooth forever



While this may all sound boring and overly in the weeds, the real-world applications of this wireless connection are going to change a lot about how people use their Bluetooth audio accessories. This includes those who use hearing aids and other devices meant to make audio accessible to those with impairments. That’s because the LC3 offers what Bluetooth has been missing for so long: the ability to have multiple synchronous connections by default.

True wireless earphones will get dramatically better



Wireless earbuds are a staple of the audio market these days, but they aren’t all the same. Qualcomm supports True Wireless stereo (left and right audio data directly to the specific earbud) with its smartphone and headphone chips from a couple of generations ago. However, default Bluetooth is stuck with the original method of transferring stereo data to one earbud and then sending a mono channel onward to the other earbud. When the new rue wireless earphones get their Bluetooth 5.2 hardware, they’ll be able to leave this issue in the dust. Additionally, by switching to LE audio, they can offer much better battery life as well.

Share your music with friends over a single source



This old method is bad for power consumption and latency. Fortunately, Audio LE supports proper true wireless earbuds using independent synchronized audio streams. Audio LE takes this further, supporting multiple-device streaming from a single source. For example, two or more listeners streaming movie audio from a laptop to their own Bluetooth headphones.



Audio Broadcast support also makes an appearance with Bluetooth Audio LE. This is a mass broadcast version that supports loads of users predominantly in public places, allowing them to tune headphones into various supported sources. Examples include TVs showing sports in bars, cinemas, or streaming TV news channels in multiple languages. For the hearing impaired, this technology integrates into hearing aids too.



Hearing aids are about to make life even easier for millions



Here’s where all this tech comes together to solve a real-world problem. While improving the lives of those who cannot hear well may not be the sexiest feature of any wireless standard, the real-life application of LC3 devices holds a lot of promise for the hard of hearing because it enables listening directly to the sources around you.



For example, there’s currently a small emitter device that looks a bit like a hockey puck demoed at CES 2020 that can enable hearing impaired users to connect their hearing aids directly to the movie they’re watching, the church sermon they’re listening to, or even sporting events. Essentially, you’re piping the live broadcast into your ear canals, instead of having the hearing aid try to record and process the ambient sound around you. Hearing aids currently suck out loud at this task because they have very glaring [url=https://www.soundguys.com/why-does-my-microphone-sound-bad-23749/]technical issues that can’t really be overcome
 in their current configuration.



Shortcomings in hearing aids is one of those more “invisible” impediments that those hard of hearing have to suffer through, but LE audio goes a long way in alleviating some of the crappier parts of going to a public event and having a tough time hearing it. While there’s no guarantee that the hardware will be available soon, Bluetooth 5.2 and LC3 seem to be extremely promising—at least from the hearing aid demo units Chris Thomas tried at CES.



When can I use Bluetooth LE Audio?



LE Audio will be bundled as part of the upcoming Bluetooth 5.2 specification. Unfortunately, we’ll have to wait for new playback sources and headphone hardware sporting Bluetooth 5.2 chips to arrive before we can test it out. But as none of this is proprietary technology, market adoption of these features will be reasonably fast.


The first hardware components supporting LE Audio will be making their way out to developers later in 2020. This suggests that the first consumer products won’t appear until very late in 2020 or early 2021. Support for Broadcast Audio may not appear in public spaces until 2022.

 2019-10-02 快速评论
人口结构的趋势性交叉将为所有消费行业带来深刻变化。这个变化已经在日本推动了食品、鞋服、化妆品、商超零售等等众多行业的适老化转型再造,让一批率先转战老年市场的企业取得丰硕成果;在中国,人口结构变化同样正在越来越明显的改变消费行业的发展趋势。

文|Ageclub
现代经济学证明,人口结构变化是影响一个经济体长期发展的最重要因素之一,体现在供给上,就是是否有足够数量和质量的劳动人口;体现在需求上,就是哪个年龄段的消费需求将主导社会经济走向。 决定未来三十年经济发展方向的中国人口结构正在发生深刻的变化——中国新婴儿潮一代人口加速老龄化与新生儿快速减少的趋势交叉! 
[图: gif]
2014-2016年,中国65岁及以上的每年净增人口数量在600万人,到了2017-2018年,每年净增800万人。1962-1975年中国新婴儿潮一代即将进入退休,每年新增老年人口将达2000万以上。 人口结构的趋势性交叉将为所有消费行业带来深刻变化。这个变化已经在日本推动了食品、鞋服、化妆品、商超零售等等众多行业的适老化转型再造,让一批率先转战老年市场的企业取得丰硕成果;
在中国,人口结构变化同样正在越来越明显的改变消费行业的发展趋势。刚刚过去的“十一”黄金周,阿里/京东/携程纷纷发布消费数据报告,中老年群体属于其中的消费亮点: 

【淘宝数据显示】
1日至3日,“爸爸秋冬外套”搜索量环比上周涨136倍,“中老年妈妈秋装上衣”搜索量比上周涨64.6倍。
去体检机构进行全面检查的中老年消费者数量比去年增长近2倍。
去医疗美容机构进行口腔护理、医美手术的中老年人也比去年增长近2倍。
45岁以上消费者是通过口碑预订功能享受最低3折错峰就餐优惠的主要人群之一,也是KTV、健身房等场所使用团购券比例最高的人群。
【京东数据显示】
用户搜索关键词前五名分别是:老人手机、足力健老人鞋、收音机、营养食品和拐杖;
在手机/电器分类中,智能手杖成为今年中老年人新宠,销量火爆,同比增长达到5倍多;
在老人日常用品中,老花镜、老年代步车、按摩椅(器)、老人定位手表的销量增长最高;从下单金额来看,按摩椅成为今年最火爆的产品,这类商品动辄数千甚至数万元。
【携程数据显示】
老年人是高频次旅行用户,65%的受访老年出游用户每年出行3次以上,且越来越多老年人能够独立完成在线预订;
7成以上的老人出游表示会考虑KOL推荐,且旅行频次越高,参与意愿越高;
超5成的老年旅游用户选择独自或和朋友出游,远超夫妻结伴出游以及和子女同游。
 中国的消费品市场虽然整体尚未开始大规模向老年市场转型,但已在诸多细分领域显现出爆发增长的趋势。 我们选取了几个品类深入分析他们的市场竞争格局,产品创新路径,为后面的不断涌现的新产品提供发展方向! 
1、比如成人纸尿裤,市场规模、消费量年复合增长率远高于女性卫生用品和婴儿纸尿布。
  [图: gif]
2012 年以来,我国成人失禁用品的消费量增长同样非常迅速,从 2012 年的 13.0 亿片增加至 2017 年的 44.9 亿片,年复合增长率达到 28.1%。而这个数据,均远高于女性卫生用品和婴儿纸尿布。
2、比如奶粉,贝因美等主打婴幼儿奶粉的企业亏损连连,雀巢、伊利布局中老年获得初步成果 根据公开资料,贝因美连续三年营收下降,从2016年的27.64亿元降至2018年的24.91亿元,扣非净利润更是大亏; 而雀巢、伊利股份等一线品牌已布局中老年奶粉市场多年,年销售额可能达数十亿元之巨。而且产品线不断丰富完善,从最基础的高钙奶粉到针对心脑血管的鱼油配方奶粉,针对肠胃消化问题的膳食纤维配方奶粉,针对阿兹海默症的专门配方奶粉等一应俱全。
3、比如轮椅,3000-5000元电动轮椅取代500元手推轮椅成为主流 从AgeClub近期统计的轮椅电商销售数据看,手推轮椅在销量上占比61%,电动轮椅占比为39%。 但从销售额统计则形势反转,电动轮椅占比69%,手推轮椅占比31%。很显然,电动轮椅已经成为电商平台轮椅品类的主导力量,或许也将很快改变线下市场以手推轮椅为主的格局。 [图: gif]
||中老年消费品市场分类:竞争同质化市场、强技术型市场、产品升级型市场
中老年消费品市场处在爆发增长阶段,机会大于风险,但同时这个市场也是个异常复杂的市场,企业必须清楚认知自身的资源、优势和战略,才能真正在中老年市场里找到机会。
1.竞争同质化市场:新旧品牌快速更迭,创造新品类是核心能力
竞争同质化市场的特点是不同品牌的产品本身的区分度很低,一个新品类、新产品出现后马上会引来一大堆模仿者,新旧品牌快速更迭,寻找、打造、塑造创新品类的能力是优秀品牌引领市场的关键。
比如在老人鞋市场上,目前市面上的中老年健步鞋分为类似足力健的新创老年鞋品牌和开发新品类进入健步鞋的传统鞋企两大类。
我们选取了5个老年健步鞋品牌进行了对比,这些品牌既有近几年新创立的老人鞋品牌,也有知名品牌的子品牌,如骆驼集团旗下的健足乐。  
[图: gif]
从相似的外观、产品特点到请知名老艺术家做代言人、大打电视广告、强推代理加盟,众多健步鞋品牌选择的打法十分雷同,将市场变成又一个一哄而上迅速做到行业大面积亏损的消费品营销案例。 这种情况在过去的中老年服装行业同样重复上演。
业内人士告诉AgeClub,淘宝上的中老年服装品牌从2010年前后就开始兴起,其中不乏年销售过亿甚至数亿的品牌,但基本上每一两年都会换一拨,很少有长期保持优势的品牌。
2.强技术型市场:跨国巨头稳居中高端,国产品牌激烈价格战
与产品同质化严重、品牌更迭频繁的鞋服等消费品相反,另一类市场则是技术优势决定市场格局。 最明显的例子是助听器,中高端市场多年来一直被国外品牌牢牢掌握,中国企业通过性价比路线也占据了不少市场份额,但新品牌层出不穷,市场排位每几年都会变化一次。
助听器市场潜在空间很大,据统计全国患有不同程度听力障碍的人群数量2.19亿人,但目前中国助听器佩戴率仅为5%,而美国为24.6%,中间有4倍以上的提升空间。
但这个市场面临国外品牌占据中高端、国产品牌在中低端同质化竞争激烈的处境。 在AgeClub对助听器电商销售数据的分析中发现,国外品牌西门子牢牢占据第一的位置,除此之外,TOP20品牌中的大部分都是国产品牌。但这些品牌之所以销售额靠前,主要靠的还是价格优势。
我们将销售额前五名的品牌作销售额与价格段的分析,可以看出中高价格段仍然被西门子等国外品牌占据,国产品牌价格段主要在300元甚至150元以下。  
[图: gif]
而国产品牌与西门子销售额差距不大的主要原因是因为,西门子的渠道重点放在线下,不重视线上市场,才给国产通过电商做大提供了机会。
但国产品牌不少是加工贴牌,比如电商平台上常见的助听器品牌一秒、雄鹿、宝尔通、邦力健等,生产厂家都是“中山市小榄镇森蓝电子厂”,但该厂没有任何助听器相关的专利。 不难发现,西门子等国外品牌技术专利优势巨大,专利数最多的前五个品牌有四个是国外品牌。
唯一一家中国品牌是福建太尔集团,其专利有32项,专注于骨传导助听器的研发生产。 
  [图: gif]
3.升级型市场:技术升级带来产品体验、场景革新,跨界创新搅动原有格局
产品的核心技术发生变化,由技术带来的产品体验显著提升,带来产品形态的升级换代和市场容量的急剧提升。
推动市场变革的,很多时候恰恰是怀揣某种核心技术优势的跨界创新者。 以轮椅为例,市场正在从手推轮椅向电动轮椅切换,而电动轮椅背后的推动力量,除了传统的医疗康复产品厂商,如鱼跃、互邦、可孚等,还有一家此前与医疗康复业务毫无关系的上市公司英洛华,却在电商平台轮椅品类中占据了第二的位置。
  [图: gif]
英洛华2016年借壳上市,旗下赣州东磁稀土有限公司主要经营范围为稀土永磁材料及其应用产品;永磁材料是生产微电机(尤其是无刷电机)的主要原材料之一,而微电机正是电动轮椅的核心组织部件。 分析专利发现,英洛华从专利总数来看,是国内轮椅品牌中最多的,为93个。
  [图: gif]
而且英洛华在电机相关方面的技术优势非常突出,其中,轮毂减震驱动装置、电机等主题的专利数量最多,分别为25项和24项。  英洛将自身在永磁、电机方面的技术优势应用到另一个原本毫不相干的轮椅市场,迅速占据了市场头部位置。
||中老年消费品市场创新实践:4大产品创新路径
中老年消费品市场的盛宴在人口结构趋势交叉的背景下才刚刚开始,不管是国外品牌还是国产品牌,不管是大企业还是小企业,未来都是机会多于风险。
而抓住机会的关键前提是充分理解中老年人群的生活场景,挖掘引导中老年人群未被满足的潜在需求,打造差异化产品,乃至塑造新的产品品类。
1、产品创新路径(一):场景拓展—电动轮椅 仔细研究中老年人的生活场景和生活需求,其实可以发现很多打造创新产品品类的机会。从中老年人的不同生活场景出发,都出现了创新产品。
  [图: gif]
一般在家中室内使用的场景,有品牌推出专门的轮椅产品,其轮毂直径较小,能够在短距离内转动方向,甚至360度转弯,能够轻松进出房间。 上下楼梯是很多住多层楼房的老人的难事,有品牌开发出背部设计有履带或底部有轮组的爬楼梯机,方便老人出门享受户外空间。 对喜欢探索大自然的中老人人群来说,普通电动轮椅已经无法满足他们的需求,越野型电动轮椅也诞生出来,配备加宽、粗纹理轮胎和较高的底盘,可以载着老人跨越崎岖路面、沼泽、雪地等复杂地况。
2、产品创新路径(二):需求挖掘——老年鞋 主流消费品市场的关注重心主要在年轻人身上,中老年人的很多细分需求其实是被漠视了。
老人鞋成功的背后是对中老年人脚部变形买不到合适的鞋的需求痛点,但中老年群体对鞋的需求还有很多很细分、差异化很大的穿鞋需求,在那些不为人注意的角落,可能正隐藏着类似健步鞋这样的大机会。
在AgeClub关于老人鞋的文章中曾提到,奥康和红蜻蜓在鞋相关的专利方面积累深厚,除了比较常见的防滑、减震、抗菌除臭等专利外,还有部分专利是特别符合中老年群体的差异化需求的,比如向发热鞋这种非常适合没有暖气的南方的产品。
3、产品创新路径(三):功效升级—蛋白粉 健康永远是中老年人群最大的需求,但健康产品同时也是同质化竞争最为激烈的市场之一。
目前市面上的蛋白粉品牌非常之多,既有进口品牌和国产大品牌,也有许多不知名杂牌充斥其中。 但仔细梳理市场上的蛋白粉产品,发现除了传统的植物蛋白粉、乳清蛋白粉和复合蛋白粉外,市场上还出现了一些新型蛋白粉,在产品的功效上大幅升级,从普通的营养补充升级到促进消化、美容养颜、提高乳铁蛋白等更具购买动力的功效上。 
[图: gif]
从消费者人群而言,由最初的成人、体质虚弱者向更加细分的人群转变,如中老年女性等。 伴随着蛋白粉产品升级的是价格大幅升级。以90克为单位来衡量,乳铁蛋白粉为996元,是普通蛋白粉的近百倍,显现出功效升级所带来的巨大产品创新价值。
4、产品创新路径(四):技术突破—助听器 在国外品牌已经占据垄断地位的市场里,比如上文分析的血压计和助听器,国产品牌如果要突破,需要在主流技术路线之外开辟一条新路。
以助听器为例,虽然国外品牌专利储备遥遥领先中国企业,但在近几年我国也出现了另辟蹊径的产品创新——比如骨传导助听器。
上文分析助听器品牌专利情况时提到的福建太尔集团,便是专门研究骨传导技术的公司。根据官网,在骨传导技术与声学领域取得了令人瞩目的成就,拥有近百项技术专利。 

目前福建太尔集团旗下的助听器品牌Vlike在天猫上有售,价格从5200元到8980元,比普通国产品牌的空气传导型助听器昂贵许多,销量也相差甚远。
显然,技术突破是比其他方式难得多的产品创新路径,但如果成功,很有可能成为一个细分领域的领跑者!

  2011年中国听力产业发展预测-比较客观

2011年中国听力产业发展预测

2011-03-08 11:36:15 作者: 来源: 中国医药报

在我国医疗卫生事业高速发展的现今时代,众多专家、业内人士对2011年中国听力产业的发展方向和重要事件做出了一些预想。




国产设备
专业技师资本介入
数字助听器国产化项目正在紧锣密鼓地进行。美国助听器专家John Moulton博士解释说,与模拟助听器不同,数字助听器的核心技术是助听器的算法程序。它就像控制计算机运行的软件程序。没有软件,再好的计算机芯片也无法工作。
中国听力学网总编汉东声说,研制具有我国自主知识产权的数字助听器一直是国人的梦想,但是,这种数字助听器的“大脑”(即算法)不能购买,而只能创造。
据悉,基于先进的0.13微米工艺的数字芯片的国产助听器已经“出炉”。参加该项技术开发的加拿大听力语音实验室首席科学家付晓毅也强调,国产助听器必须是具有自主知识产权的助听器,而不是单纯的组装产品。此次开发的助听器的算法就是在中国独立创作的,所编写的算法得到国家知识产权保护;更重要的是,该项目实现了从编程到验配、从生产到应用的系统平台,其中包括具有自主知识产权的验配软件、助听器配方公式和助听器编程适配器等一系列硬件和软件技术。该助听器能否于今年上市,成为本年度中国听力产业的一大猜想。
在过去的一年里,国产多通道人工耳蜗临床试验的启动及其远远低于进口人工耳蜗的预期销售价格,吸引了众多潜在使用者关注的目光。据了解,目前国产多通道人工耳蜗已经完成60例临床测试。然而,业内人士认为,人工耳蜗要真正实现国产化,并投入市场,可能还需要一定时间。
专业技师
中国听力学发展过程中一个巨大的障碍是人才缺乏。我国听力学专业人才培养和入门资格认定是近期才开展的。根据目前我国听力疾病患者人数,以每位患者每年做一份听力图为基数,再加上听力复查需求,我国每年至少需要测试1.32亿份听力图。这还不包括助听器验配和人工耳蜗植入等康复测试需求。如果参照每位听力师每天测试5份听力图的国际标准(按每月20个工作日计算),目前我国需要11万名听力学专业人员。
原中国残联听力语言康复中心门诊部主任、现从事助听器验配师资格认证工作的王树峰博士说,目前,在全国范围内需要通过助听器验配师职业资格培训及认定的从业人员有7万人,加上全国近10万家医疗卫生机构所需要的4万名测听技师,正好是上面提到的11万专业人士的空缺。
2007年,中国劳动和社会保障部发布的《第九批新职业目录》中首次列入助听器验配师职业。目前,已经有部分助听器验配师通过相关培训和测试,获得初步认证,这为下一步的岗位强制性认证奠定了基础。但是,一些业内人士指出,助听器验配师的职业界定仅解决了听力领域亟待规范的多种专业人才中的一种,更关键的是,必须尽快建立听力技师等专门职业,以便从根本上解决我国听力康复和学科教育面临的核心问题。
资本介入
2010年即将结束之际,国务院和国家发改委相继发布了关于开放国内医疗市场投资的一些重要政策。
2011年初,美国全球分析公司发表的报告预测,到2015年,全球听力器械市场将达到220亿美元,其中增长最快的是亚太地区——这里的听障人群占全球一半以上,但是助听器和人工耳蜗使用率却极低,该地区至少将保持9%的复合增长率,中国、俄罗斯、巴西、印度等将成为主要增长国家。
听力康复产业一直受到境外资本的密切关注。2006年,瑞士峰力集团大举并购当时国内代理优利康和峰力产品的两个公司,并在苏州建厂。随后,其他助听器厂家也纷纷在中国建厂。然而,虽然国内助听器连锁经营行业初具规模,“丽声”、“自然之声”、“惠耳”等一直受到资本青睐,但是由于行业整体规模仍偏小,投资者非常谨慎。
随着我国经济快速发展,尤其是听力康复产品相继得到政府财政补贴和资助,在一些地区,助听器可获得部分甚至完全报销,因此销量会随之剧增。预计2011年,国外助听器公司或部分股权投资者可能在具有一定市场份额和规模的助听器连锁店进行资本介入。
