Abstract
|
|
|
Developments in computer technology have made it possible to extract extremely small signals from high levels of biological background noise. Since the early 1960s, brainstem auditory evoked potentials(BAEP)have been recorded in animal brains or
from
the scalp. Soon volume-conducted BAEP were recorded from the human scalp.
Before evluating whether a recording is abnormal or not, it is essectial to have sufficient normative data. The purpose of this paper is to examine the latencies and amplitudes of BAEP waves in normal adults, and to evaluate the importance of
these
differences. We performed BAEP in 20 normal persons (40 ears), who had no history of ear disease, and had normal hearing.
@ES The results were as follows.
@EN 1) There was a significant sex effect on the absolute latency of wave V in 90dB nHL and 70dB nHL(normal hearing level).
2) There was a significant sex effect on the interpeak latencies of wave I-V and I-V and III-V in 90dB nHL and 70dB nHL.
3) There were a no significant differencies of the ratio of amplitude in wave I and wave V increasing stimulus intensity.
4) The latencies of all BAEP waves were shortened with increasing stimulus intensity.
5) There was the prolongation of latency of contralateral wave V comparing of wave V.
