An energy-saving lightbulb in my living room started blinking. (You know the ones with the swirly spiral?)
Before replacing it I recorded the electronic noise it makes using a Maplin TP-101 Telephone Pick-Up connected to my Zoom H1.
This is the first recording. The light was always on and I simply brought attached the pickup coil to the lampshade. The lightbulb would go through periods of staying on normally (no blinking) where it was mostly silent(or slight buzz). And then would go into this very irritating random flickering, when the pick-up coil would get all this electronic noise.
If you think the noise is irritating, the light flickering is actually much worse! You could not stay in the room for more than a couple of minutes without going mentally insane.
Note that when flickering the lightbulb produces no audible noise. The noise is only electronic and cannot be recorded with a normal microphone. A telephone pickup or some other type of coil must be used to record it.
