Acoustic water leak detection
Listening sticks have been used for centuries as a method of water leak locating.
Acoustic water leak detection is a non-destructive and efficient method for identifying leaks in water systems. It can be used in various settings, including residential, commercial, and municipal water supply networks. By detecting and repairing leaks promptly, it helps conserve water resources, prevent property damage, and reduce costs associated with water loss.
The escaping energy (water under pressure) forces its way through the fault which aggravates the opening causing vibrations or structure borne sound and as the water impacts the surrounding materials the pipework is buried or imbedded in such as sand, gravel, limestone, clay, bricks or other services the turbulence from the pressurised water causes vibration and sound waves. This is where acoustic or listening equipment can be used by water leak detectors.
These devices use sensitive microphones to detect the sound of water leaks. They amplify and analyze the sounds to pinpoint the source of the leak. Acoustic leak detectors are often handheld and can be used for both above-ground and underground leak detection.
Acoustic water leak detector: using a Manual listening stick
Listening sticks have been used for centuries as a method of water leak locating. Very simple tool to use as the end of the rod is placed at the desired test location, with your ear resting on the ear piece while probing along the known route of the pipeline. Generally a listening stick is fabricated with a steel rod and ear piece made from either solid wood, nylon, plastic or with a diaphragm. Below pictures is a listening stick with diaphragm.
