Time-frequency analysis of transient evoked otoacoustic emissions via smoothed pseudo Wigner distribution
1Technical Audiology, Karolinska Institute, Stockholm, Sweden.
Abstract:
Transient evoked otoacoustic emissions (TEOAEs) can be processed by the smoothed pseudo Wigner distribution (SPWD). With this process, TEOAEs can be transformed into the time-frequency plane to give a three-dimensional pattern. The analyses of shape and localization of TEOAE patterns and the comparisons of pattern differences establish a method for describing otoacoustic emissions. A better understanding and interpretation of the characteristics of TEOAEs can be achieved as well. This method can be used as a powerful tool for monitoring the cochlear condition.
