Abstract
While the mechanisms underlying cochlear filtering are no doubt non-linear, a number of investigations have indicated that cochlear spectral analysis behaves surprisingly linearly. As seen by individual fibres of the cochlear nerve, with due allowances for transducer and synaptic (no memory type) non-linearities, the filtering of broad-band and multi-component stimuli is, to a first approximation at least, well modelled by linear filters. This has been shown in discharge rate terms for broad-band noise stimuli, in the predictability of noise thresholds from pure tone thresholds (yielding measures of effective bandwidths — Evans and Wilson, 1971), and, for comb-filtered noise stimuli in terms of the predictability of response ‘contrast’ (Wilson and Evans, 1971).
