Frequency difference beyond behavioral limen reflected by frequency following response of human auditory Brainstem

Frequency difference beyond behavioral limen reflected by frequency following response of human auditory Brainstem

BACKGROUND The present study investigated whether the frequency-following response (FFR) of the auditory brainstem can represent individual frequency-discrimination ability. METHOD We measured behavioral frequency-difference limens (FDLs) in normal hearing young adults. Then FFRs were evoked by two pure tones, whose frequency difference was no larger than behavioral FDL. Discrimination of FFR...

Temporal integration reflected by frequency following response in auditory brainstem.

Auditory temporal integration (ATI) has been widely described in psychoacoustic studies, especially for loudness perception. Loudness increases with increasing sound duration for durations up to a time constant about 100 ~ 200 ms, and then loudness becomes saturated with more duration increase. However, the electrophysiological mechanism underlying the ATI phenomenon has not been well understoo...

Frequency modulation and the difference limen for frequency.

Difference limen for formant frequency discrimination at high fundamental frequencies

In previous studies of formant frequency discrimination, variation in the stimuli has mainly concerned the formant frequencies while other factors which may affect formant frequency discrimination have largely been ignored. In most studies, fundamental frequencies typical of adult male speakers have been used. In the study presented here, formant frequency discrimination as a function of fundam...
