Both use sound but very differently. Here's when to use each.
| Factor | Leak.ca | Acoustic Listening Devices |
|---|---|---|
| How it works | Two sensors, time-delay calculation, mathematical position | Single ground microphone, operator hears leak sound |
| Accuracy | Within 30cm mathematically | Within 1-2m depending on operator experience |
| Best for | Long pipe runs, pressurized mains, confirmation | Short pipe runs, quick checks, confirmation |
| Operator skill | Requires training but produces objective data | Relies heavily on operator hearing and experience |
