ABSTRACT

The auditory brainstem response(ABR) typically consists of a series of five or seven positive peaks appearing within 10 msec after acoustic stimulation. It is belived to be generated primarily from major brainstem nuclei and fiber tracts along the classic auditory pathway. The purpose of this study was to assess the latency of the ABR for its use as indications of peripheral deafness and brainstem lesions. Auditory stimuli were 2KHz logon produced by signal generator delivered through headphone. The amplified data were averaged and displayed by computer, and graphically recorded on an XY pattern. The subjects were a total of 10 adult males, who had no history of ear diseases, and all had normal hearing(ISO criteria). The results were as follows. 1) The latency of all ABR waves was shortened with increasing stimulus intensity. 2) Interpeak latencies(I-III, III-V and I-V) were not statistically different with changes in stimulus intensity above 60dB HL. 3) Latencies of wave V at different intensity varied in linear fashion, that is correlated to prolongation of wave I. 4) Mean interaural latency difference of wave V with stimulus intensity of 80dB HL was 0.12msec.
