Abstract
The extract accuracy of signal is vital to signal process, directly affects result of all next doing. To sound signal Approximate Entropy was taken as acoustics character to analyze sound signal got by experiment, and judging it´s start and stop point accurately, then extracting striking sound from original signal. It is proved by experiment result the aim of extracting striking signal is satisfied by the method and preferences.
