Acoustic Leak Detection & Profiling
Acoustic leak detection is a non-invasive method used to investigate hidden water leaks by listening for the sound and vibration created when water escapes from pressurised pipework. It is particularly useful for investigating underground water mains, central heating systems and concealed water supply pipes.
At Maystone Leak Detection, our experienced engineers use specialist acoustic profiling equipment, including ground microphones and acoustic probes, to detect and analyse these sounds. By comparing readings and adjusting the equipment to filter background noise, we can help narrow down the likely location of a leak without unnecessary excavation or damage to your property.
Technology:
Acoustic Profiling
Best for: Locating hidden leaks within underground and pressurised pipework.
Invasive or Non-invasive: Non-invasive
Detects: Sounds and vibrations created by water escaping from underground pipes or central heating systems.
Used alone or with another technology? Acoustic profiling can be used alone. It can also be combined with tracer gas testing or other specialist leak detection methods when further confirmation is required.
Suitable for: Domestic & commercial properties.

How does Maystone use acoustic profiling for leak detection?
Our engineers use specialist acoustic profiling equipment to investigate the sound and vibration created by water escaping from pressurised pipework. The method selected depends on the location, accessibility and type of pipework being investigated.
Acoustic Probe Testing
Where pipework is accessible, our engineers can place a specialist acoustic probe directly onto individual pipes to listen for sounds associated with escaping water. This is particularly useful when several pipes are located together, helping us establish which pipe may be carrying leak-related noise.
Ground Microphone Testing
For underground water leaks, we use specialist ground microphones to listen through the surface above concealed pipework. By taking readings at different locations and comparing the frequency and intensity of the sounds detected, we can narrow down the area where water is most likely to be escaping.
Our equipment can be adjusted to help filter background noise and account for different pipe materials and site conditions. Where necessary, acoustic profiling is combined with other leak detection methods to further investigate the suspected leak location.
Benefits & limitations of acoustic profiling leak detection:
Non-invasive leak detection
Locates underground leaks
Identifies individual leaking pipes
Suitable for central heating systems
Specialist frequency analysis
Suitable for different pipe materials
Reduces unnecessary excavation
Works alongside other technologies
Sound can travel away from the leak
Sound and vibration can propagate through water, pipework and surrounding ground. This means the loudest reading is not always directly above the exact location of the leak.
Background noise can affect readings
Traffic, machinery, pumps and other environmental sounds can make acoustic investigations more challenging, although specialist equipment can help filter and isolate relevant frequencies.
Not every leak produces the same level of noise
The sound generated can vary depending on factors such as water pressure, pipe material, leak size and the surrounding ground conditions. Further testing may therefore be required.
When do we use acoustic leak detection?
Acoustic profiling is particularly useful when investigating leaks within pressurised water systems. At Maystone Leak Detection, we use this technology as part of several specialist services.
Water Mains Leak Detection
Investigating underground water supply pipes beneath gardens, driveways, roads and other surfaces.
Central Heating Leak Detection
Listening for sounds associated with escaping water from suitable central heating pipework, including concealed systems.
Commercial Leak Detection
Investigating leaks within commercial water supply networks and concealed pressurised pipework.
Domestic Leak Detection
Helping locate hidden leaks beneath floors, behind walls and within household water supply systems.
Why we combine technologies
At Maystone Leak Detection, we understand that every leak is different, which is why we never rely on a single detection method in isolation. While each technology has its own strengths, combining multiple techniques allows our engineers to build a clearer picture of what is happening within your property.
By comparing the results from advanced technologies such as thermal imaging, acoustic listening, moisture mapping, tracer gas testing and other specialist methods, we can accurately confirm the source of a leak before recommending any repairs.
This approach helps us provide a more accurate diagnosis, reduce unnecessary disruption and ensure the right solution is used for your specific situation.

Common Questions about acoustic profiling for leak detection:
-
Acoustic leak detection uses specialist listening equipment to detect the sound and vibration created by water escaping from pressurised pipework. By comparing readings at different locations, our engineers can narrow down the likely position of a hidden leak.
-
Yes. Our engineers can use specialist ground microphones to listen for the sound of water escaping from underground pipes. This can help narrow down the location of a leak beneath floors, driveways, paths and other surfaces without immediately excavating the area.
-
In many situations, yes. Where several accessible pipes are located together, an acoustic probe can be placed directly onto each pipe. Comparing the sound from individual pipes can help our engineers determine which one is carrying the noise associated with the leak.
-
Acoustic profiling can be extremely useful for narrowing down the location of a hidden water leak, but the results need to be interpreted by an experienced engineer. Sound can travel along pipes and through the surrounding ground, so we may combine acoustic profiling with another technology, such as tracer gas testing, to provide additional evidence to help narrow down the likely leak location before repairs are carried out.
-
Yes, acoustic leak detection can be used to investigate leaks in plastic pipework, although results can be more challenging than with some metal pipes. Sound travels differently through plastic, and factors such as pipe depth, water pressure and surrounding ground conditions can affect the strength of the signal. Our engineers assess these factors and may combine acoustic profiling with other detection methods where necessary.
