听性稳态反应(ASSR)测试已被证实为小儿频率特异性听力评估的客观的可靠手段。ASSR通常采用调幅声作为刺激声,这种刺激声的频谱有三个成分,即载波和两个边频带成分。两个边频带与载波之间的距离为调制频率,当调制频率为70~100 Hz时,基底膜上受刺激的区域相当狭窄,因此诱发的反 The Auditory Steady-State Response (ASSR) test has been shown to be an objective and reliable measure of frequency-specific hearing assessment in children. ASSR usually uses the amplitude modulation sound as the stimulus sound. The spectrum of the stimulus sound has three components, namely the carrier wave and the two sideband components. The distance between the two sidebands and the carrier is the modulation frequency. When the modulation frequency is 70 to 100 Hz, the stimulated area on the basement membrane is rather narrow, so the induced anti
