Sweep-frequency Bekesy audiometry was used to determine the uncomfortable loudness and threshold levels for the perception of an aurally generated harmonic distortion phenomenon in normal and sensorineural hearing impaired listeners. A continuous-interrupted tone crossover uncomfortable loudness level tracking pattern is described which appears to vary with the tracked aural harmonic distortion levels. Hearing impairment was seen to elevate the intensity required to achieve overload and distortion while reducing the range from audiometric threshold to the onset of aural harmonic distortion. Consideration of these findings to suprathreshold audiometric evaluation is discussed.
采用扫频贝凯西听力测验法，测定正常听力和感音神经性听力受损受试者对听觉产生的谐波失真现象的不适响度和阈值水平。描述了一种连续-间断纯音交叉不适响度水平跟踪模式，该模式似乎随所跟踪的听觉谐波失真水平而变化。研究发现，听力损伤会提高达到过载和失真所需的强度，同时缩小从听力阈值到听觉谐波失真开始的范围。文中讨论了将这些发现应用于阈上听力测验评估的问题。
