Guidelines for estimating damage to hearing from exposure to noise have been promulgated by, among others, the National Institute of Occupational Safety and Health, the Environmental Protection Agency, and the International Organization for Standardization (ISO). The most recent guidelines are to be found in ISO Standard 1999.2, dated 1989. These documents have implications for the setting of tolerable limits for exposure to industrial noise that differ significantly from one to the other. However, there are reasons to believe that certain significant errors were present in analyses of some of the data that served as the basis for ISO 1999.2. One objective of this project is to identify and clarify any experimental errors and methodological problems in the studies used in the development of these guidelines. Predicting from pure-tone hearing levels a person's ability to understand speech in real life is of critical importance to the definition of what constitutes a significant degree of noise-induced hearing loss and, in turn, the setting of limits of exposure to noise. The relation between pure-tone thresholds and speech intelligibility tests, and between these measures and the ability of persons to satisfactorily understand speech in everyday life, are matters of controversy. The U.S. Public Health Service (USPHS) administered pure-tone threshold, sentence intelligibility, and hearing-ability rating data constitute a rich source of information on these matters that is not yet fully analyzed. The speech-test and hearing-ability rating data constitute a rich source of information on these matters. A second objective of the proposed project is, through analyses of the USPHS data, to further develop procedures for estimating, from pure-tone hearing levels, the ability of persons with hearing loss to understand sentence tests and to understand speech in real life.

估计暴露于噪音对听力造成的损害的指南 由国家职业研究所等机构颁布 安全与健康、环境保护局和 国际标准化组织 (ISO)。 最新的 指南可在 1989 年的 ISO 标准 1999.2 中找到。这些 文件对设定可容忍限度具有影响 暴露在不同环境下的工业噪声中存在显着差异 其他。 然而，有理由相信某些重要的 部分数据分析存在错误 ISO 1999.2 的基础。该项目的目标之一是确定并 澄清任何实验错误和方法问题 用于制定这些指南的研究。 从纯音听力水平预测一个人的理解能力 现实生活中的言语对于定义什么至关重要 构成严重程度的噪音引起的听力损失，并且 反过来，设置噪音暴露限度。 之间的关系 纯音阈值和语音清晰度测试，以及这些之间 人们令人满意地理解言语的措施和能力 在日常生活中，都是有争议的事情。 美国公共卫生 服务 (USPHS) 管理纯音阈值、句子 可懂度和听力评级数据构成了丰富的来源 有关这些事项的信息尚未得到充分分析。 这 言语测试和听力评级数据构成了丰富的信息来源 有关这些事项的信息。 拟议项目的第二个目标 是通过对 USPHS 数据的分析，进一步制定程序 根据纯音听力水平来估计患有以下疾病的人的能力 听力损失无法理解句子测试和理解言语 现实生活。
