摘要：
To obtain correct information, the background noise has to be removed or the sound must be purified. How to remove noise and eliminate disturbance from the measured signal, and a de-noising method based on the wavelet technique and using Morlet wavelet as the mother wavelet is therefore proposed to enable its time-frequency resolution to be adjustable it to the signal to be analyzed.
