Transient evoked otoacoustics emissions (TEOAEs) have been widely used for testing the hearing capability. TEOAEs are also useful in diagnosing the cochlea disorders of hearing losing patients, monitoring the medicine-induced ototoxicity and identifying the hearing impairment due to some special causes. In order to investigate the time-frequency distribution of TEOAEs, this article introduced a time-frequency analysis method based on the Cone-shaped kernel distribution (CKD), and compared it with several other commonly-used quadratic time-frequency analysis methods such as pseudo Wigner distribution (PWD), running-windowed exponential distribution (ED), reduced interference distribution (RID). Our simulation showed that CKD is the most suitable for describing the time-frequency features of TEOAEs. As an application, we studied 24 series of binaural TEOAE signals recorded from 12 normal-hearing adults based on this method.
