Abstract： |
The invention provides a method for finding the signal of sound transmitting source in sound transmission detecting technique, providing a method and special device for finding the signal of sound transmitting source. According to the reversibility of sound wave in the medium, it uses existing full-waveform sound transmitting detector and ultrasonic transmitter or full-waveform receiving-transmitting sound transmitter to inversely find the signal of sound transmitting source from the received sound transmitting signal, and it has higher accuracy as compared with the current common method for estimating sound source signal, and this has an important significance in judging the signal characteristic of sound transmitting source in sound transmission detecting technique and thus evaluating the characteristic of the sound transmitting source. |
