 DESCRIPTION (provided by applicant): Koronis Biomedical Technologies (KBT) proposes to develop a novel omnidirectional, low power, miniaturized hearing aid telecoil replacement module (TCRM) based on tunneling magnetoresistance (TMR) technology. It has been reported that 31.5 million Americans have hearing loss: Hearing loss affects 1 in 10 Americans and 1 in 4 households. Modern telecoils assist the hearing-impaired with telephone handsets as well as increasingly ubiquitous public address systems (hearing loops) by receiving magnetic audio signals using large, expensive wound-coils in the hearing aid. While the received magnetic audio is often superior to audio generated by acoustic microphones, wound-coils are bulky, highly directional, and subject to noise. TMR technology delivers improvements in magnetic sensor size, sensitivity, and noise rejection that represent an opportunity to significantly enhance the performance of hearing aid telecoils. KBT will design, fabricate, and test an optimized TMR sensor, adapting this technology for this use. A TMR-based omnidirectional hearing aid TCRM will be developed, tested, and integrated within a commercially available hearing aid enclosure.

 描述（申请人提供）：Koronis Biomedical Technologies (KBT) 提议开发一种基于隧道磁阻 (TMR) 技术的新型全向、低功耗、小型化助听器遥感线圈替换模块 (TCRM) 据报道，已有 3150 万美国人拥有该模块。听力损失：十分之一的美国人患有听力损失，四分之一的家庭也使用电话听筒来帮助听力受损的人。随着越来越普遍的公共广播系统（助听器）通过在助听器中使用大型、昂贵的绕线线圈接收磁性音频信号，虽然接收到的磁性音频通常优于声学麦克风产生的音频，但绕线线圈体积庞大且方向性强。 ，并且 TMR 技术在磁传感器尺寸、灵敏度和噪声抑制方面有所改进，这代表着显着提高助听器拾音线圈性能的机会，KBT 将设计、制造和测试优化的 TMR 传感器，将开发、测试基于 TMR 的全向助听器 TCRM，并将其集成到商用助听器外壳中。
