DESCRIPTION (provided by applicant): This project will develop a speech-recognition test in noise (SRTn) for use as a screening test for hearing disability, suitable for delivery over the telephone. Successful development and implementation of such a test has the potential to greatly increase awareness of hearing disorders and the numbers of persons with hearing impairment who seek services. The test will be based on the National Hearing Test that has been used for the past four years in the Netherlands. The scientists who developed that test, and who subsequently consulted with UK scientists in developing an English version (also now in use), have agreed to participate in the development of a version of the test with speech materials spoken in a Middle American dialect. The test employs spoken sequences of three single-syllable digits, presented in a background noise with a speech-shaped spectrum. The threshold is determined by an adaptive tracking procedure. This test, administered by home telephone, has been shown to be strongly correlated with average pure-tone thresholds and even more strongly with sentence recognition in noise. The sensitivity and selectivity of the three-digit telephone test as a measure of clinically significant hearing disability were 0.91 and 0.93, respectively, for disability defined by performance on sentence recognition in noise. In the first year of its availability in the Netherlands over 100,000 people elected to take this test. This represented a large increase in the total proportion of hearing-impaired persons who have had a hearing test (historically, only one in five in the US). The US version of the test will be developed, using three-digit sequences recorded by a native speaker of Middle American English. Thresholds will then be determined by telephone, for a set of approximately 50 hearing impaired and 20 normal hearing persons, using an adaptive tracking procedure. Pure-tone thresholds and standardized speech discrimination tests administered to these same listeners will be used to determine whether the high correlations between the telephone test and measures obtained in the clinic, as found in the Netherlands, can also be achieved with a US version of this test. Sensitivity and selectivity values for the test will be determined for the identification of persons with clinically significant pure-tone loss and for those with reduced speech discrimination in noise. An estimated 28 million US citizens have impaired hearing, and approximately half of them are under age 50 (NIDCD, 1996). Successful implementation of such a test in the US could greatly increase both the awareness of hearing disorders and the numbers of persons benefitting from hearing aids and other treatments. PUBLIC HEALTH RELEVANCE: The goal of this project is to develop and validate a telephone-based screening test for impaired hearing, modeled after the highly successful National Hearing Tests currently in use in the Netherlands and the United Kingdom. It is estimated that roughly 80% of the 28 million hearing-impaired persons in the US who could benefit from hearing aids have never had their hearing tested. An inexpensive, reliable, and extremely convenient test is likely to be taken by many people who suspect that they have impaired hearing but have hesitated to visit a hearing professional for testing.

描述（由申请人提供）：本计划将发展一套噪音下的语音识别测试（SRTn），作为听力残疾人士的筛选测试，适合透过电话传送。成功开发和实施这种测试有可能大大提高人们对听力障碍的认识，并增加寻求服务的听障人士的人数。该测试将以过去四年在荷兰使用的国家听力测试为基础。开发该测试的科学家，随后与英国科学家协商开发英文版（现在也在使用中），已经同意参与开发一个使用中美洲方言语音材料的测试版本。该测试使用由三个单音节数字组成的语音序列，在具有语音形状频谱的背景噪声中呈现。阈值由自适应跟踪过程确定。这项测试是通过家庭电话进行的，结果表明，测试结果与平均纯音阈值有很强的相关性，而与在噪音中识别句子的相关性更强。三位数电话测试作为临床显著性听力障碍的衡量标准，在噪声中句子识别能力定义的残疾中，灵敏度和选择性分别为0.91和0.93。在荷兰，第一年就有超过10万人选择参加这项测试。这表明接受听力测试的听障人士的总比例大幅增加（历史上，在美国只有五分之一）。美国版的测试将被开发出来，使用由母语为中美洲英语的人记录的三位数序列。然后，使用自适应跟踪程序，对大约50名听力受损者和20名听力正常者通过电话确定阈值。对这些听众进行的纯音阈值和标准化的言语辨别测试将用于确定电话测试和在诊所中获得的测量结果之间的高度相关性，如在荷兰发现的那样，是否也可以通过美国版本的该测试来实现。该测试的灵敏度和选择性值将用于识别临床上明显的纯音丧失患者和噪音中言语辨别能力下降的患者。据估计，2800万美国公民有听力障碍，其中大约一半的人年龄在50岁以下（美国国家听力与疾病研究所，1996年）。在美国成功实施这种测试可以极大地提高人们对听力障碍的认识，并使受益于助听器和其他治疗的人数增加。与公共卫生的关系：该项目的目标是仿效荷兰和联合王国目前使用的非常成功的全国听力测试，开发和验证一种基于电话的听力受损筛查测试。据估计，在美国2800万可以从助听器中受益的听障人士中，约有80%从未接受过听力测试。许多怀疑自己听力受损但犹豫是否去找听力专家进行测试的人可能会采用一种廉价、可靠、极其方便的测试方法。
