Hand-held "Sound Camera" Shows You the Source of Noises

Zothecula writes "If you work with machinery, engines or appliances of any type, then you've likely experienced the frustration of hearing a troublesome noise coming from somewhere, but not being able to pinpoint where. If only you could just grab a camera, and take a picture that showed you the noise's location. Well, soon you should be able to do so, as that's just what the SeeSV-S205 sound camera does."

Ping vs Knock

[CanHasDIY]

Knowing where the sound comes from is quite handy, but often that's only half the battle - knowing what kind of sound it is is equally important.

A 'ping' coming from your engine block has an entirely different mechanical connotation than a knock or whine from the same region.

Still cool, can't wait to see what lies ahead.

You can augment that by stuffing the end of the screwdriver into a length of rubber hose; you get the same effect, without having to stick your face 4 inches from the reciprocating assembly.

Or you can use a long screwdriver.

That's what real mechanics do.

There's only one reason to get one of these...

Somebody down below mention the other solution of using a longer screwdriver (which works very well :>) ), but your solution works and is also called a stethoscope [wikipedia.org]! I'm just not sure I'd want to have rubber tubing near a running car engine, as a hot part could melt the rubber and fuse the tube to that hot part, or a dangling loop of rubber could get caught up in some moving part or a fan-belt.

I personally think that the longer screwdriver approach is safer ! ! !
