Noises are artificially added to a real Transiently-Evoked Otoacoustic-Emission (TEOAE) signal to stimulate the collected TEOAEs signal. Then, the stimulated signal is denoised using traditional denoising method and wavelet transform method, and the results are analyzed. The suitable wavelet parameters for TEOAEs are found to improve the correlation ratio and the signal-to-noise ratio of the results, and to reduce the inspecting time.
