Abstract
Behavioral and objective estimates of cochlear response times CRTs and traveling-wave TW
velocity were compared for three normal-hearing listeners. Differences between frequency-specific
CRTs were estimated via lateralization of pulsed tones that were interaurally mismatched in
frequency, similar to a paradigm proposed by Zerlin 1969. J. Acoust. Soc. Am. 46, 1011–1015.
In addition, derived-band auditory brainstem responses were obtained as a function of derived-band
center frequency. The latencies extracted from these responses served as objective estimates of
CRTs. Estimates of TW velocity were calculated from the obtained CRTs. The correspondence
between behavioral and objective estimates of CRT and TW velocity was examined. For frequencies
up to 1.5 kHz, the behavioral method yielded reproducible results, which were consistent with the
objective estimates. For higher frequencies, CRT differences could not be estimated with the
behavioral method due to limitations of the lateralization paradigm. The method might be useful for
studying the spatiotemporal cochlear response pattern in human listeners.
