Can't figure out what this sound is. Help?

been going for two days. seems to be coming from underneath the toilet =/
it doesnt seem to be the fill valve.

Turn off the water to the toilet.
Does the tank lose water? If so, it may be a bad flapper making the fill valve work overtime.
If the tank doesn't lose water but the sound stopped, it may be a bad fill valve.

You will need to look inside the tank.

The tank does not lose water and the sound does not stop. The fill valve does not run at all (with water on or off).

edit: unless the tank needs to be filled, obviously.

I don't hear it. If you are in a house, I would have somebody slowly turn off electrical breakers. You shout if the sound goes away.

The hum doesn't sound anything like that, but more like camping in the desert in the night with an idling diesel engine a mile or so away . Besides, the hum cannot be recorded with a microphone -- been there, done that.

It does sound sorta like a cricket. It's strangely familiar... like something with an almost dead battery, or some power bricks.

My real guess is a pinhole water leak.

It sounds like a cricket to me too.

Shine a flashlight under the toilet and see if the sound stops.
