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.

该提案是对 RFA-DC-16-002 的回应，其中 NIDCD 寻求支持 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% 的美国成年人表示存在一定程度的障碍。 2008 年，12.7% 的 12 岁及以上美国人患有双侧听力损失 (HL)。 助听器行业调查 MarkeTrack VIII 报告称，只有不到十分之一的轻度听力损失人士使用助听器 扩音器，而中度至重度听力损失的十分之四的人使用扩音器，因此仍然存在 大片听障人群得不到康复而助听器效果不佳的原因。 采用多种多样且复杂，自付费用是一个需要解决的问题。 参议院关于 2013 财年拨款的报告语言“强烈敦促 NIDCD 支持以下研究拨款： 可能会带来更便宜的助听器，因此更多人可以使用和负担得起此类助听器 作为促进国家听力保健的主要联邦机构，NIDCD 正在积极寻求 除了成本之外，从公共卫生角度解决可及性问题也是主要障碍之一。 助听器的采用仍然是音质，助听器仍然不能完全满足所有需求 听障消费者的需求。 Creare 及其在男孩城国家研究医院 (BTNRH) 的合作者计划开发和 传播开源音频处理平台，以促进助听器 (HA) 研究的创新。 这项努力的成果将是一款用户友好、便携、可升级和可穿戴的“主助听器”（MHA）， 将允许在更广泛的范围内协作开发和开放交换新的处理算法 听力研究界，包括学术界和工业界 MHA 使用的硬件有一个。 开放、发布的设计架构，使用电子市场上现有的组件。 设想三个级别的用户：(1)“专家”用户直接在固件中实施和测试新算法 通过一个接口，使他们能够访问硬件的基本功能（音频输入和输出， (2)“开发者”用户在软件应用程序上进行交互 编程接口（API）级别修改已在固件中实现的算法的参数和 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进行某种程度的参数控制的“预编程”算法，以测试 可穿戴主助听器可用的放大变体的相对优势。
