Or even a television. You frequency is very close to the line frequency.

Computer monitors tend to be higher.

I've got a number of recent recordings with a significant signal at 
16KHz (or 15,792 Hz perhaps)?

Is there some well known source for noise of this frequency? Or 
electrical effect (power transmission lines interacting with  MD 
recorders?) known to cause it?

The noise appears in MD recordings from 2 different recorders, with 2 
different microphones, with both soundcard digitization of analog 
playback from the MDs and with digital transfer of PCM data. And I see 
it in spectrograms computed with several different programs.

Any hints would be appreciated!
