Abstract
Hearing was studied using speech, audiometer MA-31 and rise and fall of loudness in 365 workers exposed to industrial noise only and 86 workers exposed to noise and dust containing lead. Identification of the front of growing loudness was impaired more in persons exposed to lead-containing dust; therefore they have more serious central hearing defects.
摘要
采用言语、MA - 31听力计以及响度的升降对365名仅暴露于工业噪声的工人和86名暴露于含铅噪声和粉尘的工人进行听力研究。在暴露于含铅粉尘的人群中，对响度逐渐增强前端的辨别能力受损更严重；因此，他们存在更严重的中枢性听力缺陷。
