本文对织布车间接触稳态工业噪声[95～105dB(A)]引起耳聋工人151耳和正常青年人的52耳作对照,采用MadsenZS77-MB型声阻抗测试仪进行测试,并用Damplex AS-72型听力计进行纯音测听,根据Jerger(1977年)预估听闻的公式:
In this paper, we compared the steady state industrial noise (95 ~ 105dB (A)] in weaving workshop with 151 ears of deaf workers and 52 ears of normal young people. The samples were tested with Madsen ZS77-MB acoustic impedance tester and Damplex AS-72 Audiometry pure tone audiometry, according to Jerger (1977) estimated hearing formula:
