한국어 초록
The main objective of this study was to determine the effect of stimulus rate and gender on auditory brainstemresponse (ABR) latency and amplitude in Korean young adults. A total of thirty young adults consisting of fifteenmales and fifteen females participated in the study. We performed this study by analyzing the latencies andamplitudes of ABR wave I, Ⅲ, and V as a function of low stimulus rate and gender. The stimulus repetition ratewas changed in five steps: 8, 16, 21, 32, and 64/s. Experimental results showed that when stimulus rates increased,significant differences in the latency and amplitude of wave I, Ⅲ, and V were observed while a gender effect wasfound on the latency of wave Ⅲ and the amplitudes of wave I and Ⅲ. As stimulus rates increased, the latencies ofwave I, Ⅲ, and V consistently and progressively increased, whereas the amplitudes of ABR waves inconsistentlychanged. The latency shift became longer in wave V than wave I and Ⅲ. The amplitude of wave I, Ⅲ, and Vwas greatest at a stimulus rate of 21/s and least at a stimulus rate of 32/s, compared to those of other stimulusrates. This study will provide beneficial information in developing proper strategies that optimize and enhance theABR wave latencies and amplitudes in different gender groups, saving the ABR test time in clinical applications,and establishing a quantitatively normative database for clinical purposes.영어 초록
The main objective of this study was to determine the effect of stimulus rate and gender on auditory brainstemresponse (ABR) latency and amplitude in Korean young adults. A total of thirty young adults consisting of fifteen
males and fifteen females participated in the study. We performed this study by analyzing the latencies and
amplitudes of ABR wave I, Ⅲ, and V as a function of low stimulus rate and gender. The stimulus repetition rate
was changed in five steps: 8, 16, 21, 32, and 64/s. Experimental results showed that when stimulus rates increased,
significant differences in the latency and amplitude of wave I, Ⅲ, and V were observed while a gender effect was
found on the latency of wave Ⅲ and the amplitudes of wave I and Ⅲ. As stimulus rates increased, the latencies of
wave I, Ⅲ, and V consistently and progressively increased, whereas the amplitudes of ABR waves inconsistently
changed. The latency shift became longer in wave V than wave I and Ⅲ. The amplitude of wave I, Ⅲ, and V
was greatest at a stimulus rate of 21/s and least at a stimulus rate of 32/s, compared to those of other stimulus
rates. This study will provide beneficial information in developing proper strategies that optimize and enhance the
ABR wave latencies and amplitudes in different gender groups, saving the ABR test time in clinical applications,
and establishing a quantitatively normative database for clinical purposes.
