Short buzzing sound coming into bedroom
« on: September 25, 2013, 07:22:28 PM »
I live in a condo above a coffee shop. At certain times during the day a buzz/hum at around 120 - 250 Hz can be heard for five second intervals.

I have hardwood floors and the ceiling below are panels that can be pushed up and moved. I'm not sure what kind of insulation is above them. The source of the noise isn't directly below my bedroom either.

Any suggestions? I'd rather not rip up the hardwood because I think it is continuous with the rest of the condo, so I think changing the height would be a problem.

the best thing you can do is locate the source and have it decoupled from the structure otherwise you might spend a lot of money and not reduce the problem enough or at all. When you find out the source let us know and we can help with a solution to the problem.

Thanks for the reply. I'm not sure that I can work with the noise source since it is a coffee shop that I don't have access to. I did have some success reducing the noise and wonder if there's more that I can do.

The noise source is not directly below my bedroom. It's below a closet next to my bedroom. I think that the buzzing is traveling from the hardwood in the closet to the hardwood in my bedroom. I put a rubber exercise mat on half of the hardwood in the closet and weighted it down. This has reduced the sound considerably. Is there a better material to use for this? I'm planing on putting an area rug in the closet.

Sure, you can try our mass loaded vinyl w/ closed cell foam , this is our best underlayment and I would advise doing wall to wall for best results.
