I’m not scared of things going bump in the night. At least, I’m not scared when I’m in my own house with my wife and her highly trained attack cat poised to pounce. Things might be different if I were to find myself all alone in a derelict and deserted building like a hospital or factory in the wee hours of the morning.

What I do fear is waking up to things that go “drip… drip… drip…” in the middle of the night. Even worse than hearing a “drip… drip… drip…” is the fear of a pinhole lurking leak that’s not yet made its presence felt. I speak from experience. We had such a leak behind the fridge-freezer in our kitchen a few years ago. We only realized we had a problem when the wooden floors started to buckle. We were forced to move out of the house for three weeks while everything was being fixed.

I rent my office in a big building along with many other companies. There’s a plumber in the office next to mine. A few weeks ago, he showed me a super sensitive acoustic sensor he uses to detect leaks. The sensor plugs into a high gain amplifier that feeds a set of headphones. The volume is capped to stop your head exploding if someone sneezes. This sensor is so sensitive that it can be used to pin down the location of the smallest leak behind a wall.

I love learning and sharing things like this, which is why our mission here at DENA is to keep you informed about the latest and greatest technologies and tools.
