Noise below through walls
« on: October 01, 2013, 03:15:26 PM »
There is a hum coming from below but I can tell that it is not just coming in through the floor, but the walls as well. How would you go about stopping sound from below going up into the walls and out to the room?

It looks like I posted this in the wrong place. I actually own this condo so I can do extensive work if needed.

I believe it is his refrigerator. I can also hear other appliances like a garbage disposal and blender.

I know that there is about 1.5 feet of open space (no insulation) between his ceiling and my floor. Would filling that with R19 or something else help at all?

Insulating the cavity is helpful for airborne noise and the standing wave in the cavity but it will not change the problem of the disposal, blender and refrigerator. The refrigerator and blender can put on vibration pads.

as far as the disposal, not going to happen...you need to decouple from the structure in order to see a noise reduction..anything that is connected to the frame of the building is structural vibration and is far harder to reduce than airborne sound.

So even if I were to use MLV on the floors and green glue, sound clips and MLV in the wall, that would not quiet a coupled vibration?

sure it would quiet it down, it is a very expensive approach. if you could get your neighbor to assist in the solution you could save 99% of the cost. with of course the disposal noise but that is not constant.
dont get me wrong, the system is a kick butt system and is what we do for recording studios and high noise environments..I just look at it from a cost vs reduction stand point...$1,000 's of dollars vs. $100 with better results.

Feel free to give me a call direct and we can discuss it :)
