Temporal suppression of the click-evoked otoacoustic emission level-curve

The nonlinearities in the inner ear (the cochlea) in humans are still not well understood. By using otoacoustic emissions, this paper estimates the time varying properties of this nonlinearity, in a way that has not been attempted before. The findings were incorporated in a state-of-the-art time domain cochlear model by Verhulst et al. (2012) dx.doi.org/10.1121/1.4763989, which can be used to accurately simulate peripheral auditory processing. Bianchi et al. (2013) dx.doi.org/10.1007/s10162-013-0406-z used this study to explore time varying nonlinearity and its role in the precedence effect – a perceptual phenomenon describing the dominance of directional auditory information, vital for human communication.
