Abstract
A system for the measurement of auditory function from 8000--20 000 Hz is described. This system introduces advances in: (a) maximum power output, (b) signal fidelity, and (c) transducer characteristics. Two case studies are presented to illustrate the clinical information gained from the measurement of high-frequency auditory sensitivity, which is not readily apparent in conventional threshold assessment.
摘要
本文描述了一种用于测量8000至20000赫兹听觉功能的系统。该系统在以下方面取得了进展：（a）最大功率输出；（b）信号保真度；（c）换能器特性。文中给出了两个案例研究，以说明通过测量高频听觉敏感度所获得的临床信息，这些信息在传统阈值评估中并不容易显现出来。
