Abstract: Leak location devices and methods of using leak location devices that can be used in conjunction with negative pressure wound therapy systems are disclosed. In some embodiments, a leak location device can include a microphone for detecting sound pressure produced by a leak. Detected sound pressure can be compared to a threshold, which can correspond to background or ambient sound pressure. Background or ambient sound pressure can correspond to sound produced by a negative pressure source. The leak detection device can include a display configured to visually depict the detected sound, and a light source which creates a visual depiction of the coverage angle of the microphone.
