摘要
The acoustic leak detection system with environmental noise isolation provides for the acoustic detection of leaks in a pipe while minimizing interference from external or environmental noise. The acoustic leak detection system includes a hollow shell adapted for positioning about the pipe to be inspected. A pair of gaskets are circumferentially secured to the inner surface of the hollow shell so that the pair of gaskets bear against the outer surface of the pipe to form an acoustically isolated region defined between the pipe, the pair of gaskets and the inner surface of the hollow shell. An acoustic sensor, microphone or the like is mounted on the hollow shell within the acoustically isolated region for detecting any acoustic signals; i.e., the sound produced by a leak in the pipe within the acoustically isolated region. Upon detection of a leak, an alert signal is generated.
