【摘要】：目的:探讨正常成人言语声诱发的听性脑干反应(s-ABR)各波的电生理特性,分析其与受试者噪声下言语识别能力及性别的关系。方法:以40ms时程的复合语音/da/为刺激声,诱发40例母语为汉语的健听成人的s-ABR,分析s-ABR各波的引出率,潜伏期、V/A斜率(V-A峰峰值与V-A波间期之比)与受试者性别的关系,以及V/A斜率与噪声下言语识别阈间的关系。结果:s-ABR引出的7个反应波形中,女性受试者的V、A、O、F波潜伏期较男性短(均P0.05),其余各波潜伏期受性别影响小,差异无统计学意义(P0.05);噪声下言语识别阈与V/A斜率呈负相关(r=-0.478,P0.05),即V/A斜率越大,噪声下言语识别阈越低。结论:言语信息中随时间快速变化的高频辅音所诱发的神经反应受性别影响明显,随时间变化较慢的低频元音部分所诱发的神经反应受性别影响小;瞬态变化信息处理能力好的受试者,其噪声下言语识别能力也越好。
[Abstract]:Aim: to investigate the electrophysiological characteristics of auditory brainstem response (BAR) waves induced by speech sound in normal adults, and to analyze the relationship between these waves and speech recognition ability and sex of subjects under noise. Methods: s ABR was induced in 40 healthy adults whose mother tongue was Chinese. The relation between gender and the ratio of V / A peak and V / A peak to V / A peak in the latent period and V / A slope were analyzed. And the relationship between V / A slope and speech recognition threshold under noise. Results among the 7 response waveforms induced by the ratio s-ABR, the latency of the VAO OF wave in the female subjects was shorter than that in the male (all P 0.05), and the other latencies were less affected by sex. There was no significant difference between speech recognition threshold and V / A slope under noise, i.e., the larger the V / A slope, the lower the speech recognition threshold under noise. Conclusion: the nerve response induced by high frequency consonant in speech information is obviously affected by sex, and the nerve response induced by low frequency vowel which changes slowly with time is less affected by sex. The better the transient change information processing ability, the better the speech recognition ability under noise.
