DESCRIPTION (provided by applicant): TOPIC - Tooth Phone(R) Auditory Device - TPAD ABSTRACT The Tooth Phone(R) Auditory Device - TPAD is new alternative device to the only direct bone conduction hearing aid currently accepted by the Food and Drug Administration (FDA) for the treatment of certain specific types of hearing loss. Unlike the precedent FDA approved device that uses an osseointegrated implant as the site for skull stimulation, the TPAD uses a natural tooth. Compared to the precedent device, the TPAD has many important advantages such as cost, safety, longevity, fidelity, and cosmetics. In the TPAD system, ambient speech and sound is picked-up by a microphone and radio transmitted to a removable orthodontic-like retainer worn on the palate. An audio processor and novel transducer (actuator) embedded in the retainer then transmits the speech vibrations via the bone conduction pathway to the cochlea. Numerous prior studies have been performed on the TPAD during development of a related voice communication device for the US military. The objective of Phase 1 is to show that the teeth are equivalently sensitive to sound input when compared to a dental implant within the same subject. To help demonstrate this objective, a new methodology is proposed in which a novel accelerometer (sensor) is attached to the teeth. The sensor records skull vibrations from different input devices and skull stimulation sites. This methodology can provide valuable insights into the bio-physics of bone conduction transmission. Through frequency analysis of skull vibrations, the sensor can demonstrate the nature of skull harmonic overtones, and potentially help solve the question of how and why individuals with single- sided deafness can localize sound. The objective of Phase 2 is to build and test an auditory device that can pass FDA 510-K equivalence requirements. PUBLIC HEALTH RELEVANCE: This project will provide an auditory device alternative to the widely accepted Bone Anchored Hearing Aid or Baha(R) . It also introduces a novel tooth sensor instrument that can be used for the direct measurement of within-subject bone vibratory patterns and frequency responses.

描述（由申请人提供）：主题 - 牙齿手机（R）听觉设备 - TPAD摘要牙齿电话（R）听觉设备 - TPAD是食品药品监督管理局（FDA）目前唯一接受某些特定类型的听力损失的新替代设备。与使用骨整合植入物作为头骨刺激的位点的先例FDA批准的设备不同，TPAD使用天然牙齿。与先例设备相比，TPAD具有许多重要的优势，例如成本，安全性，寿命，保真度和化妆品。在TPAD系统中，麦克风和无线电传输到戴在味觉上的可移动正畸样固定器的无线电拾取环境语音和声音。然后，嵌入在固定器中的音频处理器和新型换能器（执行器），然后通过骨传导途径传输语音振动到耳蜗。在为美国军方开发相关的语音通信设备时，已经对TPAD进行了许多先前的研究。第1阶段的目的是表明，与同一受试者中的牙齿植入物相比，牙齿对声音输入等效。为了帮助证明这一目标，提出了一种新的方法，其中新型加速度计（传感器）附着在牙齿上。传感器记录了来自不同输入设备和颅骨刺激位点的头骨振动。该方法可以为骨传导传播的生物物理学提供宝贵的见解。通过对颅骨振动的频率分析，传感器可以证明颅骨谐波色彩的性质，并可能有助于解决一个问题以及为什么单面耳聋的人可以定位声音的问题。第2阶段的目的是构建和测试可以通过FDA 510-K等效要求的听觉设备。公共卫生相关性：该项目将为广泛接受的骨骼锚固助听器或巴哈（R）提供一种听觉设备。它还引入了一种新型的牙齿传感器仪器，可用于直接测量受试者内部骨振动模式和频率响应。
