Low-frequency Hum in my house.
- Thread starter CBM
- Start date
I think you have narrowed down that you have a mechanical vibration from the ground exciting your house creating audible noise and vibration. I suggest finding a civil engineer with some experience in structural vibration control and damping to come out and suggest remedies for damping your house structure at those frequencies. I imagine there are remediation methods where you can damp your structure based on the vibration frequency and lengths of certain walls and beams in your house that resonate at that frequency.

Thank you. I will download it now and try a recording tonight when it seems louder.
You say you stuck your ear to the wall/floor and it got louder?
Do the same with the mic.Stethoscope styles. Record with an app that’s not voice focused, which could be possibly drowning out non-telephone band noise as mentioned above.

I made some measurements last night using my UMIK-1 and Audacity. When I imported them into REW I see the there is a lot of variability below 300 Hz which surprised me. I expected the curves to be uniform at low frequencies. I was also disappointed that I have to get very close to my subwoofer to hear the sound, but it's there. In real life it is much louder. Anyway, I've attached some of the files taken in 2 rooms where it seems to be loudest. Tonight I will take some measurements against the walls and floor and maybe outside on the sidewalk. I'm not sure how the mic will work when it's touching a surface, but I will give it a try. Thanks to everyone who is trying to help us figure this out. It's maddening and costing us sleep.

I guess I hear what you are refering to in Bath 3.

To finding the source of the hum you can use a long screwdriver and hold it on waterpipes/walls/streetlights and the handle direct onto your ear (hint for bearing check). Go through the house/outside/neighborhood to find the loudest spot.

It's very similar but our noise seems to be lower frequency. You can almost feel it. What is this sound?

I like that idea. The neighbors already think we're crazy. lol

Yes. When I listen on my stereo I have to turn it up so high that I hear a lot of hiss from the mains but if I get close to the subs I can hear it.
