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）：该提案对NIDCD特别招标RFA-DC-12-004做出响应，以改善获得听力医疗保健的访问。特别是，NIDCD正在寻求解决方案，以降低听力医疗保健的成本并改善服务不足人群（例如残疾人和资源有限的社区）的访问权限。实现主动目标的技术包括用于远程评估和监视的远程医疗技术，用于家庭监控的设备，移动和便携式评估系统以及不需要特殊培训并且可以在低资源环境中运行的设备。失真产品耳声排放（DPOAE）比其他形式的听力评估具有许多优势：它们是一种敏感的客观筛选工具，具有良好的重测可靠性 进行筛选；它们可以与各个年龄段的儿童和成年人一起使用；它们是一种快速，有效的计算机化筛选方法。但是，DPOAE测量系统往往比筛选听力计（5至10倍）要昂贵得多，并且它们容易受到仪器引起的噪声（如果手持式系统，则来自持有系统的人，或者来自患者的绳索摩擦）以及生物学噪声。 Creare建议开发低成本（<$ 1000），移动，用户友好的耳声排放（OAE）探针，并具有自适应噪声排斥和降低噪音以进行听力筛选。即使在嘈杂的条件下，自适应噪声排斥和降低算法也将SNR提高至少10 dB。我们提出的创新将通过允许对儿童以及智障成年人的低成本听力筛查来增加获得听力健康服务的机会，并能够监视噪声引起的噪音引起的对噪声暴露的患者的耳蜗损害，这些患者可能不容易获得此类筛查技术，尤其是矿工，农民，农民和其他噪音曝光的工人，他们居住在偏远地区。最后，基于移动的OAE探测器将在低资源国家找到广泛的应用程序，利用电池供电的仪器来进行婴儿和儿童期筛查。
