Perhaps the most striking evidence for active processes operating within the inner ears of
mammals and non-mammals alike is their ability to spontaneously produce sound. Predicted …

Frequency analysis of sound by the cochlea is the most fundamental property of the auditory
system. Despite its importance, the resolution of this frequency analysis in humans remains …

Abstract When David Kemp discovered “spontaneous ear noise” in 1978, it opened up a
whole new perspective on how the cochlea works. The continuous tonal sound emerging …

Frequency tuning within the auditory papilla of most non-mammalian species is electrical,
deriving from ion-channel resonance within their sensory hair cells. In contrast, tuning within …

Frequency selectivity is a key functional property of the inner ear and since hearing research
began, the frequency resolution of the human ear has been a central question. In contrast to …

The present study objectively quantified the efferent-induced changes in the sharpness of
cochlear tuning estimates and compared these alterations in cochlear tuning between adults …

Lizard auditory papillae have proven to be an attractive object for modelling the production
of spontaneous otoacoustic emissions (SOAE). Here we use an established model (Vilfan …

Quasiperiodic fluctuations with frequency are observed in a variety of responses that either
originate from or strongly depend on the cochlea's active mechanics. These spectral …

Spontaneous otoacoustic emissions (SOAEs) are weak sounds that emanate from the ears
of tetrapods in the absence of acoustic stimulation. These emissions are an epiphenomenon …

Across the wide range of land vertebrate species, spontaneous otoacoustic emissions
(SOAE) are common, but not always found. The reasons for the differences between species …
