Everything is relative. You know how the drip, drip, drip from the leaky faucet in the bathroom sink will seem as loud as a bass drum, keeping you up all night? In the daytime you never heard or noticed it. But now, in the middle of the night, when the house is quiet and free of distracting noises, it’s loud and clear.
That’s why, in years gone by, professionals used to locate leaky pipes by using the quiet time in the middle of the night to isolate the sound of escaping water. While this technique can be effective in a residential setting, it has limitations in facilities that run 24/7. Fortunately, professionals now have a second option: Magnifying the sound of the leak so that it’s much louder than the background noise. Again, everything is relative.
