DESCRIPTION (provided by applicant): This proposal responds to the NIDCD special solicitation RFA-DC-12-004 for improving access to hearing healthcare. In particular, the NIDCD is seeking solutions to lower the cost of hearing healthcare and improve access for underserved populations (such as the disabled and communities with limited resource access). Technologies that achieve the initiative objectives include telehealth technologies for remote evaluation and monitoring, devices for in-home monitoring, mobile and portable assessment systems, and devices that do not require special training and can operate in low-resource environments. Distortion product otoacoustic emissions (DPOAEs) offer many advantages over other forms of hearing assessment: they are a sensitive objective screening tool with good test-retest reliability for screening; they can be used with children and adults of all ages; and they are a fast, efficien computerized screening method. However, DPOAE measurement systems tend to be significantly more expensive than screening audiometers (5 to 10 times as much) and they are susceptible to noise caused by the instrument (either from the person holding the system if it is handheld, or from the cord rubbing on the patient), as well as biological noise. Creare proposes to develop a low-cost (<$1000), mobile, user-friendly otoacoustic emissions (OAE) probe with adaptive noise rejection and noise reduction for hearing screening. Adaptive noise rejection and noise reduction algorithms improve the SNR by at least 10 dB even in noisy conditions. Our proposed innovation will increase access to hearing health services by allowing low-cost hearing screening for children as well as adults with intellectual disabilities, and it will enablethe monitoring of noise induced cochlear damage for noise exposed patients who may not have easy access to such screening technology, in particular, miners, farmers, and other noise exposed workers who live in remote locations. Finally, a mobile-based OAE probe will find wide applications in low resource countries leveraging the cellular network with a battery-powered instrument to conduct infant and childhood screenings.

描述（由申请人提供）：本提案响应了NIDCD特别征集RFA-DC-12-004，旨在改善获得听力保健的机会。特别是，NIDCD正在寻求解决方案，以降低听力保健的成本，并改善服务不足的人群（如残疾人和资源有限的社区）的获得。实现该倡议目标的技术包括用于远程评价和监测的远程保健技术、家庭监测设备、移动的和便携式评估系统，以及不需要特别培训并可在资源匮乏环境中运行的设备。畸变产物耳声发射（DPOAEs）与其他形式的听力评估相比具有许多优点：它是一种敏感的客观筛查工具，具有良好的重测信度 用于筛查;它们可以用于所有年龄的儿童和成人;并且它们是一种快速，高效的计算机化筛查方法。然而，DPOAE测量系统往往比筛查听力计昂贵得多（5至10倍），并且它们容易受到仪器引起的噪声（如果是手持的，则来自手持系统的人，或者来自在患者上摩擦的绳索）以及生物噪声的影响。Creare建议开发一种低成本（<1000美元），移动的，用户友好的耳声发射（OAE）探头，具有自适应噪声抑制和降噪功能，用于听力筛查。自适应噪声抑制和降噪算法可将SNR提高至少10 dB，即使在噪声条件下也是如此。我们提出的创新将通过为儿童和智障成年人提供低成本的听力筛查来增加听力健康服务的可及性，并将使那些可能难以获得此类筛查技术的噪声暴露患者，特别是矿工，农民和其他居住在偏远地区的噪声暴露工人，能够监测噪声引起的耳蜗损伤。最后，基于移动的OAE探测器将在资源匮乏的国家得到广泛应用，利用电池供电的仪器利用蜂窝网络进行婴儿和儿童筛查。
