243 workers occupationally exposed to noise have been examined by pure tone audiometry and impedance audiometry. Hearing disturbance have been diagnosed in 145 cases (62%). Impedance audiometry was performed in 74 subjects. In 47 cases (70%) hearing thresholds were found consistent in both methods whereas the other 21 cases (30%) showed different hearing thresholds. Thirteen individuals of that group exhibited hearing impairment in the cochlea. Hearing loss has been simulated in two cases. The Lüscher-Zawisłocki test revealed 1-1.5 dB in all cases. Objective verification of loudness recruitment phenomenon allowed to state cochlear hearing localization in 31 cases.
对243名职业性接触噪声的工人进行了纯音听力测定和声阻抗测听检查。145例(62%)被诊断有听力障碍。对74名受试者进行了声阻抗测听。47例(70%)两种方法测得的听力阈值一致,而另外21例(30%)的听力阈值不同。该组中有13人存在耳蜗听力损伤。2例模拟了听力损失。吕舍尔-扎维斯洛茨基试验在所有病例中均显示为1 - 1.5分贝。响度重振现象的客观验证使得31例能够确定为耳蜗性听力定位。
