- Help me solve a way to not hear 80 hz waves inside my home.
My neighbor has two AC condensers are driving me insane.
I took measurements of the units, and they were between 33.5db - 47.9db at 80HZ.
About 3 feet away is a cinderblock privacy fence between us. It is about 10 feet tall. His home is on an elevation about 4 feet higher than mine (so the fence on his side is 6 feet). And then about 8 feet away is my home.
Inside my bedroom, I was finding 31.5db at 80 HZ when ambient is 11.7db, and this spike is causing a lot of disturbance whenever their ACs kick in and is on.
After complaining, they put noise absorption blankets on the units as well as filled in part of the cinderblock wall with concrete.
Sadly, this made things worse everywhere except a decrease right above the wall (49.6dB to 35.1dB) and right next to the wall (35.5dB to 13.3dB) - both of which are outside and I don't care about. Inside the bedroom, things went from up by 2-4dB at the 80 HZ. What's worse are the things that wasn't such a big deal before such as my bathroom (18.1dB to 24.6dB) and my closet which was no noise before to where I didn't measure to now being 24dB at 80HZ as well as other parts of the house where there was no issue before. I also took a measure from the far corner of my backyard and since adding the concrete, the measurement went from 25.4 to 29.1dB at the 80 HZ.
So now we know that filling in part of the cinderblock wall made it worse.
What can we do to make it better and eliminate the noise?
I've been told that soundproofing my own home won't work due to the low frequency of the noise so I'm stuck.
Please help get rid of this rumble.
