Normative Data For Clinical Abr Audiometry

Abstract

The use of Clinical Instrument for diagnosis purpose necessitates norms. The following paper postulates norms for ERA, TA-1000, using 2 KHz logon tone at two intensity level 80 dB and 100 dB for absolute latencies I to V, Absolute Amplitude I, III and V, Interwave latencies I-III, III-V and V-I, and relative amplitudes I/III, III/IV, and I/V, based on 20 individuals tested.
