Abstract

The effects of impulsive noise exposure upon hearing sensitivity from 8000 to 20000 Hz were determined for a sample of 23 young military veterans. The subjects' histories consisted primarily of major incidents of weapons fire. Based on audiometric configuration, the subject sample was divided in two groups characterized by predominantly unilateral or bilateral shifts in threshold sensitivity. This division was consistent with history information. The main finding was extensive threshold shifts from 8000 to 20000 Hz which was highly individual-specific and unpredictable. High frequency audiometry frequently revealed extensive changes not evident in the 250 through 8000 Hz range.

摘要

对23名年轻退伍军人样本，测定了脉冲噪声暴露对8000至20000赫兹听力敏感度的影响。受试者的经历主要是武器射击的重大事件。根据听力测定配置，受试者样本被分为两组，其特征是阈值敏感度主要为单侧或双侧变化。这种划分与历史信息一致。主要发现是8000至20000赫兹范围内广泛的阈值变化，这是高度个体特异性且不可预测的。高频听力测定经常显示出在250至8000赫兹范围内不明显的广泛变化。
