Frequency characteristics of neuromagnetic auditory steady-state response to sinusoidally amplitude modulated sweep tones

摘要：

　　Auditory steady-state response(ASSR)is an electrical component of neuronal activity encoding information of periodic modulations of a sound.The ASSR is specifically characterized by its sensitivity to carrier frequencies(fc),providing a useful measure with respect to evaluating the perceptual hearing characteristics per fc,particularly at threshold levels.However,the frequency characteristics of the ASSR at the supra-threshold levels remain limited or unclear,despite its possible application,for instance,to adjust the hearing aids objectively and automatically.Thus,this study aimed to capture precisely the frequency characteristics of the ASSR for wider fc at finer resolution.The relationship with loudness was also examined.
