An acoustic vibration receiver which is sensitive to the frequency of the low-frequency air pressure generator and which is characterized in that artificial sound waves easy to penetrate the layer of earth can be generated in a chamber formed by water leakage after that a water-air compound with certain frequency waves is filled into the chamber is provided on the ground of the water pipe to be tested. A gap degassing switch with a degassing outlet connected with a water-using valve port of a water pipe is provided in a degassing channel of the air compressor. An air compressor with a low-frequency air pressure generator is provided. The present invention discloses a method for detecting leakages on water pipes by using artificial sound waves.
