The typological features of short-term acoustic adaptation (STAA) and its applicability for evaluating the hearing resistance to noise effects were investigated in those working in a noisy environment. The experiments were carried out on 29 subjects with normal hearing and 46 patients with neurosensory hypoacusis, including 25 patients with occupational hypoacusis. The STAA magnitude was evaluated as the difference between the hearing threshold of the 20 msec signal paired with a preceding adapting signal or without it. The duration of the adapting signal was in the range 20-1000 msec and its intensity was 40 dB over the hearing threshold. The signals were applied at 50 msec intervals. The STAA value was 5-25 dB in 90% normal subjects. In the patients with occupational hypoacusis, the hearing degradation increased as STAA declined. The patients with common neurosensory hypoacusis did not show such a relationship. It is recommended to use STAA as a measure of man's hearing resistance to noise effects.
对在噪声环境中工作的人员，研究了短期听觉适应（STAA）的类型学特征及其在评估听力对噪声影响的抗性方面的适用性。对29名听力正常的受试者和46名神经感觉性听力减退患者进行了实验，其中包括25名职业性听力减退患者。STAA幅度被评估为与先前适应信号或无先前适应信号配对的20毫秒信号的听力阈值之间的差异。适应信号的持续时间在20 - 1000毫秒范围内，其强度比听力阈值高40分贝。信号以50毫秒的间隔施加。90%的正常受试者的STAA值为5 - 25分贝。在职业性听力减退患者中，随着STAA下降，听力退化加剧。普通神经感觉性听力减退患者未显示出这种关系。建议使用STAA作为衡量人类听力对噪声影响抗性的指标。
