It listens across an array of microphones rather than one, and calculates where each sound is coming from. The Fluke ii900 we use carries 64 microphones for this, which is what lets it overlay a colour map onto a live camera image and pinpoint the actual fitting or joint a leak is coming from, not just the general area.
More microphones give finer spatial resolution, the difference between knowing a leak is somewhere on a wall of pipework and knowing which fitting it is. A 64-microphone array is also what lets the imager work from several metres away, rather than needing a single sensor pointed directly at a suspected joint.
2 kHz to 52 kHz. Human hearing tops out around 20 kHz, so most of that range, including where a compressed air leak's turbulence is loudest, is inaudible to begin with. That gap is the entire reason acoustic imaging finds leaks a walk-through never will.
It's a genuine engineering estimate, not a lab measurement. The imaging software converts the sound level it picks up into an estimated flow rate using a model built from measuring a large number of real leaks at different flow rates and pressures. What the estimate is reliable for is consistent, repeatable prioritisation across every leak found on a site.
It needs reasonable line of sight to the source. Ideal working distance is roughly 1 to 8 metres, with useful detection extending to about 21 metres given a clear view. Strong wind and background noise reduce accuracy, since the imager is filtering for a specific sound signature and wind adds noise across those same frequencies.
Thermal imaging looks for a temperature difference and only reliably picks up larger orifices, roughly 1 mm and up. Acoustic imaging listens for the turbulence a leak generates regardless of temperature, which is why it catches the small leaks that make up most of a typical site's leak count.
Yes, but indoor, production-hours conditions are where it performs best. Wind and ambient outdoor noise sit across the same frequency bands the imager is listening on, which reduces accuracy compared with a sheltered indoor line.
The imager itself can also pick up gas and vacuum leaks, but LeakHawk's audits are scoped to compressed air. We don't run partial discharge or mechanical/bearing diagnostics. That's a different tool, the Fluke ii910, which we don't use.
Yes. No cost and no obligation. We run a limited number each month so we can do them properly.
No. The imager works during normal production. We just need safe access to the line and someone who knows it.

We complete your site induction, bring our own PPE and follow your permit requirements. Let us know what you need when you book.
You get a one-page summary. If a full audit makes sense we'll say so and send a proposal. If it doesn't, we'll tell you that too.
There's no published flat rate. Every site's scope (size, number of lines, access) is different, so we quote after an initial conversation about your site.
If the leaks found on the day don't add up to more in estimated annual cost than the audit fee itself, the audit is free. It's assessed against the audit fee, not against any repair costs.
No. The report and the repair quote are yours regardless of what you decide next. Some sites use their own maintenance team, some use another contractor, some use LeakHawk. All three are fine.
No. The scan happens live, while the line runs at full production. There's no isolating equipment or shutdown required for the audit itself.
South East Queensland and Northern NSW, including Brisbane, the Gold Coast, the Sunshine Coast, Ipswich and Toowoomba.
Yes. Public liability cover and standard site inductions are sorted before we arrive. Audits are scoped and run against ISO 11011 leak survey guidance.
It depends on current bookings and how big the site is. We'll confirm a realistic timeframe once we've scoped your site, rather than quote a generic promise upfront that may not hold as booking volume changes.
Every leak found, logged individually with its location, a photograph from the acoustic imager, an estimated flow rate, and an estimated annual dollar cost, ranked so the highest-cost leaks are easy to prioritise first.
Yes. A full sample report is available to download. The site, leak locations and figures in it are a representative example, not a real client's results.
It's a genuine engineering estimate built from the measured sound level and distance to each leak, not a lab-grade flow measurement, but it's consistent and repeatable enough to prioritise a repair budget on.
You do. There's no obligation to use LeakHawk for anything after the report is delivered.
A recurring re-survey service on a set cadence, so you can track whether leak load is actually falling over time and confirm that what was flagged last time actually got fixed.
No. It's a new service line we're still proving out commercially. Registering interest just starts a conversation about whether a cadence makes sense for your site.
New leaks start the moment the last batch are fixed. Vibration and thermal cycling don't take a year off, so a single audit is a snapshot of one day, not a permanent state.
Yes. No cost, no obligation, no login for any of them.
No. They're straight downloads from the Free Resources page.
A printable kit, instructions, a log sheet and 48 tags, so your own team can tag the leaks they can hear before booking a scan for the rest. LeakHawk supplies the kit; your team does the physical tagging.
No. It's a two-minute self-assessment based on what you already know about your site. The hot-zone scan and full audit are what actually measure your leaks.
