This can also be cause by a worn pressure reducing valve. This valve reduces the high pressure from the city to a pressure which is approriate for your house. When they get old, they sometimes get sticky, causing sudden water pressure changes ... or even slow changes resulting in what can be heard as a hum or a whine.

Locate the valve, get a friend to go flush the toilet, listen at the valve for the sound. Your next step would be to replace it if the source seems obvious. You can learn how (not a newbie task) or hire a competent handyman to do it.
