DESCRIPTION (provided by applicant) Every year millions of hearing tests are conducted in the U.S. for a variety of reasons, including diagnosis of ear disease, evaluation of communicative function, monitoring effects of noise and ototoxic medications. prospective research studies, and fitting of hearing aids. Although there is a "standard" hearing test method, the rules are vaguely defined and loosely followed. This project is designed to develop an automated method for testing hearing sensitivity. It is designed to achieve similar test results to those obtained by expert audiologists while standardizing the method, eliminating errors, increasing efficiency, and decreasing cost. The method preserves the salient features of routine audiometry while applying well-accepted principles of auditory psychophysics. Contralateral masking is presented to the non-test ear whenever the test signal may be audible in that ear. In addition to automating the sequence and timing of stimuli, the method provides quality indicators that alert the audiologist to potential errors due to patient factors or inappropriate masker levels. In this Phase I project, a testable prototype will be developed, preliminary testing will be conducted on normal-hearing and hearing-impaired adult subjects, and modifications to the prototype will be made based on the preliminary evaluation. PROPOSED COMMERCIAL APPLICATION: Hearing tests conducted by audiologists in the U.S. number in the millions per year. The automated method that will be developed in this project has advantages of standardization, increased efficiency, greater accuracy, and reduced cost. The method is expected to be a software add-on to new audiometers and a retrofit to existing audiometers. There are about 1200 audiometers sold annually in the U.S. an additional 800 outside the U.S. Because the method will add a small increment (about 10%) to the cost of audiometers, the takeup rate is expected to be high.

描述（由申请人提供）每年数百万的听力测试是 出于多种原因在美国进行，包括诊断耳朵 疾病，沟通功能的评估，噪声的监测影响和 耳毒性药物。前瞻性研究和听力的拟合 艾滋病。尽管有一种“标准”听力测试方法，但规则模糊不清 定义并松散地遵循。该项目旨在开发自动化 测试听力灵敏度的方法。它旨在实现类似的测试 结果是由专家听力学家获得的结果，同时使 方法，消除错误，提高效率和成本降低。这 方法在应用时保留例行听觉的显着特征 听觉心理物理学的经过良好接受的原则。对侧掩蔽是 每当测试信号听到时，都会呈现给非测试耳朵 耳朵。除了自动化刺激的序列和时机外，该方法还 提供质量指标，使听力学家警告可能发生的潜在错误 患者因素或不适当的掩蔽水平。在这个阶段的项目中，一个 将开发可测试的原型，将对 正常听力和听力受损的成人受试者以及对 原型将根据初步评估制作。 拟议的商业应用： 听力学家在美国的听力测试每年数百万。该项目将开发的自动化方法具有标准化的优势，提高效率，更高的准确性和降低的成本。该方法有望成为新的听力计的软件附加组件，并且对现有听力计的改造。美国每年大约有1200张听众仪，美国以外的800次有800张，因为该方法将使听力计的成本增加少量增量（约10％），预计使用率将很高。
