  • Title: [Examination of reaction time--auditory brainstem responses--ABR in noise induced temporary and permanent threshold shift].
    Author: Janczewski G, Kochanek K, Dawidowicz J, Tanzariello A, Dobrzyński P, Bardadin J.
    Journal: Med Pr; 1991; 42(1):37-42. PubMed ID: 1921713.
    Abstract:
    This study was conducted to investigate the differences between auditory brainstem responses--ABR recorded in men with temporary or permanent threshold shifts (TTS or PTS). Behaviorally, the tested ears showed insignificant differences in the hearing thresholds at frequencies in the range 0.25-8 kHz. The latency of waves I, III, V and interwave intervals I-III, III-V, I-V were analysed as functions of stimulus intensity. The comparisons between recordings obtained in groups with TTS and PTS showed significant differences in latencies of wave V at 90 dB nHl only. The latencies of waves I, III and interwave intervals were unaltered.
