Description:
<jats:p>Click elicited evoked responses have gained widespread clinical use as a measure of the neurological and audiological integrity of the auditory brain stem structures. Typically, the clicks are presented at various intensity levels and the elicited responses are compared interaurally as well as with established norms. This study was conducted to determine the influence of the spectrum of the transduced click on the latency and amplitude characteristics of the averaged response elicited at various intensity levels [Clicks (100-μs square waves) were presented monaurally at 50, 60, 70, and 80 dB nHL]. Spectral analysis of the transduced signals indicated that the frequency response characteristics of the earphones significantly influenced the bandwidth of the signal. Furthermore, one earphone introduced a significant amount of intermodulation distortion into the transduced signal. The influence of the transduced signal on the inter- and intrasubject characteristics of the evoked potential will be presented.</jats:p>
