A New Analysis Method for the Evaluation of Transient Evoked Otoacoustic Emissions

An analysis system with the Matlab 4.2 system with a filter bank is presented that provides graphically created 2D and 3D views of responses in the frequency, time and amplitude coordinates. Smoothed spectral and noise responses are presented. The start end and maximum TEOAE amplitude latencies are...

Zusammenfassung:An analysis system with the Matlab 4.2 system with a filter bank is presented that provides graphically created 2D and 3D views of responses in the frequency, time and amplitude coordinates. Smoothed spectral and noise responses are presented. The start end and maximum TEOAE amplitude latencies are presented graphically and calculated numerically. The fast Fourier transformation (FFT), filter bank and wavelet transforms were developed and compared for the TEOAE analysis purposes.
