摘要：
It is introduced in this paper the principle of wavelet de-noising, wavelet base, the choice of wavelet decomposition level, the wavelet threshold selection for signal de-noising effect is analyzed. Matlab software for simulation study is made on the wavelet noise reduction; In the seabed sediment acoustics parameters test and analysis of the seabed sediment, the ultrasonic test signal wavelet noise is reduced, and the noise reduction signal is analyzed in time domain and frequency domain, it is shown that the wavelet noise reduction can retain the signal characteristic information in each frequency band, and not cause distortion in the time domain.
