为了探讨噪声对听力损害的规律,验证“工业噪声卫生标准”和制定噪声性耳聋诊断标准提供科学根据。我们对接触80～105dB(A)稳态噪声工人进行调查研究,选择资料完整的2583例进行临床听力分析。从本组资料来看,噪声作业工人听力损失的特点首先是高频受损,然后又累及中、低频部分,其听力曲
In order to explore the law of noise damage to hearing, to verify the “industrial noise health standards” and to develop noise-based deafness diagnostic criteria to provide a scientific basis. We conducted a survey on steady-state noise workers exposed to 80-105 dB (A), and selected 2583 patients with complete data to conduct clinical hearing analysis. From this group of data, noise workers hearing loss is characterized by the first high-frequency damage, and then affected the middle and low frequency part of the audiometry
