Other cases I've faced are:

4. Power line hum getting into the recording system.
5. Acoustic hum from florescent lights.
6. Noise from photocopier drum warming getting into
   the power circuit with chirps every 12.6 seconds.

I think Fons is onto something, find the cases for noise
reduction, study the noise content, and devise or apply a
suitable noise algorithm.

For my above cases Audacity's noise reduction is useful.
I'm not in a high fidelity situation.

Cheerio....
