High-resolution measurements of distortion product otoacoustic emissions (DPOAEs) from
three different experimental paradigms are shown to be in agreement with the implications …

Human auditory steady-state responses were recorded to four stimuli, with carrier
frequencies (fc) of 750, 1500, 3000 and 6000 Hz, presented simultaneously at 60 dB SPL …

Background How does the cochlea analyse sound into its component frequencies? In the
1850s Helmholtz thought it occurred by resonance, whereas a century later Békésy's work …

Distortion-product otoacoustic emissions (DPOAEs) elicited with stimulus frequencies less
than or equal to 8 kHz have been used in hearing clinics to assess whether the middle ear …

Derived-band auditory brainstem responses (ABRs) were obtained in 43 normal-hearing
and 80 cochlear hearing-impaired individuals using clicks and high-pass noise masking …

Outer hair cells (OHC) are key to the mammalian cochlear amplifier, powered by the lateral
membrane protein Prestin. In this study, we explored age-related OHC changes and how the …

Transduction of sound in mammalian ears is mediated by basilar-membrane waves
exhibiting delays that increase systematically with distance from the cochlear base. Most …

This study examined gender differences in f1-and f2-sweep distortion product otoacoustic
emission (DPOAE) phase delay measures in 60 normal-hearing human adults. Phase delay …

To date, objective measurements and psychophysical experiments have been used to
measure frequency dependent basilar membrane (BM) delays in humans; however, in vivo …

Distortion-product-otoacoustic-emission (DPOAE) phase-versus-frequency functions and
corresponding phase-gradient delays have received considerable attention because of their …
