For the past three days I've been hearing/feeling this loud reverberating hum coming from the wall in my kitchen. I cannot pinpoint an actual source, and there doesn't seem to be any rhyme or reason for when it comes. Sometimes it will be once and then not again for hours, then this morning it happened 4 or 5 times in a row. I live in a townhouse, but the neighbor on the side where it's happening isn't home. Everything in the house is electric (no gas).

Here is my best attempt to capture it. It gets quiet at the end, but that's more the recording. In reality, it fades out very consistently from loud to quiet.

Any ideas of what could be causing this are very much welcome! Thanks!

That sound reminds me of a resonant water line. Could you, or your neighbor, have a leaking upstairs toilet, or an ice maker that runs intermittently? It doesn't take much flow to send a water line into resonance, a toilet valve that cracks open to refill a tank that has lost just a little bit of water could do it.

Our main floor toilet (the level we hear the sound) has been running for a few weeks. We've been turning the water off on it until my 4 year old insists on using it since she's too lazy to walk upstairs. There seems to be no rhyme or reason to this sound, though. It's not connected to us using the water or that toilet and still happens when that toilet is shut off. We do get a water hammer sometimes when we turn off the water or take a shower. Someone else in my neighborhood suggested an issue with the water pressure regulator.

I'm going to call a plumber tomorrow! But I'm glad to have a few ideas other than a possible poltergeist. Thanks for the response!
