PROJECT SUMMARY This proposal responds to RFA–DC-16-002, in which the NIDCD is seeking to support the development of acoustic signal processing tools that have the potential to accelerate research studies and to facilitate the translation of novel algorithms for hearing aids. Approximately 15% of American adults report some degree of hearing trouble, and 12.7% of Americans aged 12 and over experience bilateral hearing loss (HL). The 2008 hearing aid industry survey MarkeTrack VIII reports that less than 1 in 10 people with mild hearing loss uses amplification, while only 4 in 10 people with moderate-to-severe hearing loss use amplification, leaving still a large swath of the hearing impaired population without rehabilitation. While the reasons for poor hearing aid adoption are diverse and complex, out-of-pocket costs rank high as an issue to be addressed. And in fact, the Senate Report Language for FY2013 appropriations “strongly urges NIDCD to support research grants that could lead to less expensive hearing aids, so such aids could become accessible and affordable to more people." As the lead federal agency promoting the nation’s hearing healthcare, NIDCD is actively seeking to address accessibility from the public health perspective. Aside from cost, one of the primary barriers to hearing aid adoption remains sound quality, and the sense that hearing aids are still not quite able to meet all the needs of hearing impaired consumers. Creare and its collaborators at Boys Town National Research Hospital (BTNRH) plan to develop and disseminate an open-source audio processing platform to spur innovation in Hearing Aid (HA) research. The result of this effort will be a user-friendly, portable, upgradable and wearable “master hearing aid” (MHA) that will allow collaborative development and the open exchange of new processing algorithms within the broader hearing research community, including both academia and industry. The hardware used in the MHA has an open, published design architecture, using components currently available on the electronics market. We envision three levels of users: (1) “expert” users implement and test new algorithms directly in firmware through an interface that gives them access to the basic features of the hardware (audio input and output, power management, housekeeping, etc.); (2) “developers” users interact at the software application programming interface (API) level to modify parameters of the algorithms already implemented in firmware and evaluate their performance in a variety of conditions; and (3) “professional” users have access to “pre-programmed” algorithms with some degree of parameter control through a simple user interface, to test the relative benefits of amplification variants available with the wearable master hearing aid.

项目摘要 该提案对RFA – DC-16-002的响应，NIDCD试图支持开发 声学信号处理工具有可能加速研究并促进 助听器新算法的翻译。大约15％的美国成年人报告了一定程度的 听力障碍，12.7％的12.7％的12岁及以上经历双边听力损失（HL）。 2008年 助听器行业调查Marktrack VIII报告说，有10人中有不到1人有轻度听力损失的用途 放大，而中度到重度听力损失使用的10人中只有4个 听力障碍的大部分损害了人口而没有康复。助听器不良的原因 收养是潜水员和复杂的，自付费用排名很高，因此要解决的问题。实际上， 参议院报告2013财年拨款的语言“强烈敦促NIDCD支持研究赠款 可能会导致较便宜的助听器，因此此类辅助工具可能会变得更加可及 人们。 从公共卫生的角度解决可及性。除了成本外， 采用助听器仍然是合理的质量，并且助听器仍然无法满足所有人的感觉 听力障碍的消费者需求。 Creare及其在男孩镇国家研究医院（BTNRH）的合作者计划开发和 传播一个开源音频处理平台，以刺激助听器研究（HA）研究。这 这项工作的结果将是一种用户友好，便携式，可升级和可穿戴的“主助听器”（MHA）（MHA） 将允许合作开发和开放式新处理算法的开放交流 听力研究社区，包括学术界和行业。 MHA中使用的硬件具有 开放，已发布的设计架构，使用当前在电子市场上可用的组件。我们 设想三个级别的用户：（1）“专家”用户直接在固件中实现和测试新算法 通过一个接口，使他们可以访问硬件的基本功能（音频输入和输出， 电力管理，家政服务等）； （2）“开发人员”用户在软件应用程序上进行交互 编程接口（API）级别以修改固件和 评估他们在各种条件下的表现； （3）“专业”用户可以访问 通过简单的用户界面具有一定程度的参数控制的“预编程”算法，以测试 可穿戴大师助听器可用的放大变体的相对好处。
