Abstract

Work has been completed at the Environmental Acoustics Laboratory during the past year on developing an industrially feasible Loudness Discrimination Index (LDI) Test. Data obtained on experimental subjects who had been exposed to brief, high-level sound showed that the maximum Loudness Discrimination Index Shift (LDIS-Max.) is a valid and reliable indicator of temporary, noise-induced, hearing change. This test is better suited to industrial usage than the traditional TTS test. Suggestions for the implementation of LDI testing in the industrial setting are discussed.

摘要

过去一年里，环境声学实验室已完成了一项工作，即开发一种在工业上可行的响度辨别指数（LDI）测试。在接触过短暂高强度声音的实验对象身上获取的数据表明，最大响度辨别指数变化（LDIS-Max.）是暂时性噪声诱发听力变化的有效且可靠指标。该测试比传统的暂时性阈移（TTS）测试更适合工业应用。文中还讨论了在工业环境中实施LDI测试的建议。
