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关于改善获得听力保健的特别征集RFA-DC-12-004。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(如残疾人和资源获取有限的社区)的机会。实现倡议目标的技术包括用于远程评估和监测的远程保健技术、用于家庭监测的设备、移动和便携式评估系统，以及不需要特殊培训且可以在低资源环境中运行的设备。失真产物耳声发射(DPOAEs)与其他形式的听力评估相比具有许多优点：它们是一种敏感的客观筛查工具，具有良好的重测可靠性 用于筛查；它们可用于所有年龄的儿童和成人；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贵得多(5到10倍)，而且它们容易受到仪器(如果是手持设备，则来自手持系统的人，或来自患者身上的脐带摩擦)以及生物噪声造成的噪声的影响。Creare建议开发一种低成本(1000英镑)、移动、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即使在噪声条件下也能使信噪比提高至少10dB。我们拟议的创新将通过允许为智障儿童和成人进行低成本听力筛查来增加获得听力健康服务的机会，并将使噪声暴露患者能够监测噪声导致的耳蜗损伤，这些患者可能无法轻松获得此类筛查技术，特别是居住在偏远地区的矿工、农民和其他噪声暴露工人。最后，基于移动的OAE探头将在低资源国家得到广泛应用，利用蜂窝网络和电池供电的仪器进行婴儿和儿童筛查。
