Variables Affecting Speech Evoked Auditory Brainstem Responses
摘要
Abstract
Objective To study variables affecting speech evoked auditory brainstem response (s-ABR) and report its electrophysiological characteristics. Methods Effects of stimulus rates (11.1/s and 20.0/s) and stimulus intensities (80 dB SPL and 60 dB SPL) on s-ABRs were studied in 24 healthy adults (24 ears), using a 2 × 2 × 6 factorial experimental design. s-ABR waveform scores, latencies and amplitudes of the feature peaks were analyzed. Results Stimulus rate had no effects on waveform scores of all s-ABRs and latencies of feature peaks (p>0.05), or amplitudes (except for peak V). Stimulus inten⁃sity seemed to affect latencies of feature peaks (except for peak A, F and O) (p<0.05), but not amplitudes of feature peaks (ex⁃cept for peak V and O). Different stimulus rate and intensity combinations had little effects on s-ABR waveform scores, laten⁃cies or amplitudes of feature peaks. Conclusion The characteristics of s-ABR are maintained across a range of stimulus rates and intensities, and not affected by different combinations of stimulus rate and intensity. A relatively wide range of stimulus intensities and rates can be selected based on needs in s-ABR testing.关键词
