项目摘要

The World Health Organization reports that nearly a half billion people suffer from a disabling hearing loss worldwide. Hearing loss is typically measured in the standard audiometric frequency range, 250 to 8,000 Hz. However, the young, healthy human frequency range of hearing extends to about 20,000 Hz. Extended high- frequency hearing loss (>8,000 Hz) is rarely assessed in the clinic but is a widespread, natural, age-related condition that begins as early as young adulthood. It is unknown to what extent extended high-frequency hearing loss affects daily functioning. This proposal assesses the ecological value of extended high-frequency hearing for speech perception and spatial awareness in realistic settings, which will include spatially separated talkers having different head orientations in reverberant conditions. There are three specific aims. Aim 1 will generate a high-fidelity multi-directional anechoic speech database with a representative cohort of adult native speakers of American English. This database is designed to be used for speech perception experiments and will be made publicly available. Speech spectral energy across the full range of human hearing will be examined, as well as the nature of speech radiation toward different directions around the talkers. Aim 2 will test the effect of simulated loss of extended high frequencies on speech perception and spatial awareness for listeners with normal hearing out to 16 kHz. These experiments are based on our recent observation that extended high frequencies in speech provide a benefit for speech-in-speech recognition. We will determine the magnitude of this benefit in realistic settings and the factors responsible for it. Aim 3 will test the effect of natural loss of extended high frequencies on speech perception and spatial awareness. Forms of natural loss that will be studied include hearing loss at extended high frequencies and the wearing of face coverings (masks) by talkers. The proposed studies will establish the ecological utility of extended high frequencies for speech communication. Valuable insight will be gained as to how extended high-frequency hearing loss impacts daily living for otherwise normal-hearing listeners. It is expected that results of the proposed studies will aid in ongoing efforts to (1) improve clinical measures of hearing loss and (2) improve hearing-aid processing techniques.

世界卫生组织报告称，近 5 亿人患有致残性听力损失全世界。听力损失通常在标准听力频率范围（250 至 8,000 Hz）内测量。然而，年轻、健康的人类听觉频率范围延伸至约20,000赫兹。扩展高频率听力损失（>8,000 Hz）很少在临床上进行评估，但它是一种广泛的、自然的、与年龄相关的听力损失早在成年早期就开始出现这种情况。尚不清楚高频延伸到什么程度听力损失影响日常功能。该提案评估了扩展高频的生态价值现实环境中的言语感知和空间意识的听力，其中包括空间分离说话者在混响条件下具有不同的头部方向。具体目标有三个。目标1将生成一个高保真多向消声语音数据库，其中包含具有代表性的成年母语群体说美式英语的人。该数据库旨在用于语音感知实验和将被公开。整个人类听觉范围内的语音频谱能量将是检查，以及讲话者周围不同方向的语音辐射的性质。目标2将测试扩展高频的模拟损失对语音感知和空间意识的影响听力正常的听众可达 16 kHz。这些实验基于我们最近的观察语音中扩展的高频为语音中的语音识别提供了好处。我们将确定在现实环境中这种好处的大小以及造成这种好处的因素。目标3将测试效果语音感知和空间意识中扩展高频的自然损失。自然损失的形式将研究的内容包括高频下的听力损失和面罩的佩戴（面具）由谈话者。拟议的研究将确定扩展高频的生态效用言语沟通。将获得关于高频听力损失如何扩展的宝贵见解影响听力正常的听众的日常生活。预计拟议研究的结果将有助于持续努力 (1) 改善听力损失的临床测量和 (2) 改善助听器加工技术。
