The amplitude-modulation-following response as an audiometric tool
The amplitude-modulation-following response (AMFR) is a sinusoidal auditory-evoked potential recorded to continuous, sinusoidally amplitude-modulated tones. Kuwada, et al. (1986) defined the AMFR and argued its audiometric utility. The current study consisted of four experiments designed to demonstrate the utility of the AMFR. The experiments were: (1) demonstration of the cochlear site-specificity of the AMFR in high-pass and low-pass masking paradigms and comparison of behavioral and AMFR thresholds using spectral analysis; (2) valuation of the influence of sleep on the AMFR; (3) examination of the effects of modulation frequency on the AMFR; and (4) assessment of the effect of sensorineural hearing loss on the AMFR. Subjects in this study were six normal-hearing and three hearing-impaired adults.
