Acoustic Testing

When unexplained water loss, pressure changes or signs of a concealed leak affect a commercial or industrial site, acoustic testing can help narrow the search area. Sensitive listening equipment is used as part of leak detection acoustic testing to identify sounds associated with pressurised water escaping from pipework.

Discuss acoustic testing with a plumbing business

Pinpointing suspected leaks with less disruption

A concealed water leak can be difficult to investigate in a facility, strata building, plant room or external service area. Water may travel away from the source, while the affected pipework sits below a slab, behind a wall, under landscaping or within a service corridor. Acoustic testing is a leak detection method that listens for the vibration or noise created when pressurised water escapes from pipework.

For commercial and industrial properties, acoustic testing can help a plumbing business narrow the likely fault location before excavation, demolition or repair work is considered. The result is not a remote diagnosis; sound conditions, pipe layout and site activity all influence how an investigation is planned.

How acoustic testing leak detection works

Water escaping from a pressurised pipe can create a sound signature that travels through the pipe, nearby fittings, surrounding ground, walls or slabs. During acoustic testing, the plumbing business listens at accessible points and compares where that sound is strongest.

Depending on the site and suspected pipe route, this may involve listening at meters, valves, hydrants, hose taps, exposed pipework or fittings. Ground-surface testing may also be used over a suspected route. The investigation may focus on water mains, copper or plastic pipework, concealed runs, services beneath slabs, landscaped areas, car parks and plant rooms.

Equipment may include ground microphones, listening sticks, headphones, contact sensors, probes and amplifiers. Acoustic testing commercial sites can be more complex where traffic, pumps, plant, building vibration or general operating noise compete with the sound being investigated.

When acoustic testing may be considered

Acoustic testing may be relevant where a site has signs consistent with a possible hidden water leak, such as unexplained water consumption, meter movement, pressure loss, damp flooring, water staining, ponding, corrosion or recurring make-up water demand. A constantly running pump, hot or cold spots, or an issue around a riser, ceiling space, wall cavity, slab or underground main may also prompt further investigation.

These signs can have different causes. A plumbing business will need to consider the water supply layout, pressure zones, fixture use, pipe material, meter behaviour, previous repairs and whether the issue appears constant or intermittent.

Acoustic testing is one part of leak detection

Leak detection acoustic testing is one way to investigate suspected pressurised water loss. It may be used on its own where conditions are suitable, or alongside other methods where the site requires more evidence before repair work proceeds.

  • Correlation testing may be considered alongside acoustic methods to compare leak sound between points on a pipe route.
  • Pressure testing can form part of investigating pressure loss.
  • Hydrogen tracer gas testing may be considered as another leak detection approach.
  • Data logging and meter review can help assess water use and meter behaviour over time.
  • Cable, conduit and service locating or subsurface scanning may be relevant before excavation.

The appropriate approach depends on access, pipe material, depth, site noise, operating conditions and the available information about the suspected leak.

Information that helps a commercial investigation start well

Clear site information can help a plumbing business understand the issue and plan access. Before making contact, gather what is readily available rather than delaying an enquiry for every detail.

  1. Note the affected area and when the issue was first noticed.
  2. Identify whether hot or cold water appears to be affected, if known.
  3. Provide water bills, meter readings, photos, site plans or hydraulic drawings where available.
  4. Record meter, valve, riser and plant-room locations, along with any known pipe material or previous repairs.
  5. Explain access arrangements, operating hours, site inductions, noise sources and any suitable quiet testing period.
  6. For managed or industrial sites, identify the authorised contact and any shutdown, permit, isolation, environmental or production considerations.

Choosing a plumbing business for acoustic testing

Commercial acoustic testing often requires coordination around access, operational continuity and site conditions. When comparing plumbing businesses, describe the suspected leak area, the building or asset involved, the available site records and any restrictions that could affect an investigation.

Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia. It is backed by the Association, which has represented Western Australia’s plumbing and gasfitting industry since 1901. Choosing a Master Plumber can help customers make a more informed choice of plumbing business for their property or project.

Equipment and supply names customers may encounter

Documentation, quotations or site discussions may refer to equipment and supply-channel names such as Reece, Galvins, Tradelink, Sewerin, Gutermann, HWM, SebaKMT, Primayer, Testo, Fluke, Rothenberger, RIDGID, Milwaukee or Subtronic. These are examples customers may encounter in relation to plumbing supplies or leak detection equipment; their presence does not determine which investigation method is suitable for a particular site.

Related leak detection options

If acoustic testing is not the only investigation required, a plumbing business may consider the broader leak detection process and related methods according to site conditions. Correlators, data logging, hydrogen gas detection testing, pipe microphones, audits and cable and conduit location are related options within commercial and industrial leak detection.

Frequently asked questions

What is acoustic testing for leak detection?

Acoustic testing uses sensitive listening equipment to detect sound created by pressurised water escaping from pipework. The sound can travel through pipework, surrounding ground, walls, slabs or fittings, helping narrow the likely leak area.

Where can acoustic testing be used?

It is commonly used around water mains, copper and plastic pipework, services under slabs, landscaped areas, car parks, plant rooms and concealed commercial pipe runs.

Can background noise affect the test?

Yes. Traffic, pumps, plant rooms, building vibration and other background noise can affect the sound being investigated. A staged approach or a quieter testing period may be considered on some sites.

Will acoustic testing always identify the exact leak location?

Acoustic testing can help narrow the location by following a leak sound signature, but results can be affected by pipe material, soil, pressure, pipe depth and background noise. Further testing may be considered where needed.

What should be provided before testing begins?

Useful details include the suspected leak area, meter and valve locations, pipe material if known, water pressure issues, site plans, operating hours, access requirements, noisy equipment and previous repair history.

Can acoustic testing be used with other leak detection methods?

Yes. Depending on site conditions, it may be used with correlation, pressure testing or tracer gas testing, as well as other leak detection methods.
