Abstract:
A method of obtaining evoked otoacoustic emission (EOAE) response data, comprising:generating a variant of a standard MLS wherein the âˆ’1s and +1s in the standard MLS are replaced by +1s and 0s respectively in the variant, using the variant MLS as stimulus signals, sensing response signals to the stimulus signals, deconvolving the stimulus and response signals in real time as the variant MLS is being generated in order to provide a deconvolved MLS waveform, detecting in the deconvolved MLS waveform non-linear temporal interaction components (NLTICs), and recording the NLTICs as slices through higher order Volterra Kernels with each Volterra Kernel representing a term in a Volterra series which models the stimulus/response system.
