Abstract
Wavelets analysis was performed to obtain time-frequency representations of otoacoustic emissions (OAEs) from normal ears. High S/N ratio emissions evoked by click stimuli at 16 different intensity levels were recorded from healthy subjects and used as test material. Time-frequency representations were used to analyse the relationships between frequency components and latencies
