Blocking sound for common wall w/o using panels?
« on: February 02, 2009, 12:27:57 AM »
I share a common wall in a rental apartment with a neighbor that has an annoying hacking cough.  It is probably due to some medical issues but it is annoying for me to have to hear it every 5-10 minutes.  I've been researching soundproofing a common wall and most of the recommendations I've come across involve using 4 X 8 drywall panels glued to the existing wall in combination with something like green glue or mass loaded vinyl panels.  The problem is, I live on the 6th floor of the building and there is no way for me to transport 4 x 8 panels to my unit.   First, my landlord will probably ask what I was doing transporting sheetrock to my unit and second, I don't have a car/truck to do this.  Also, I don't want to do anything involving permanently altering the existing wall (i.e. gluing a drywall panel to the existing wall).

Is there some way to create modular soundproof panels that  can be hanged on the walls much like a picture frame?  The common wall is only about 9' X 7'.  I've thought about creating 3 3' wide by 7' high soundproofing panels than can be designed as artwork to be hanged on the walls.    Would something like this be effective and can it be done for under $200??

Sorry to say, but just hanging some panels on the wall will not work. Sound is just like water it will go where there is the least amount of resistance. If you dont address the entire wall you will not get a reduction. I would say since you cant do any construction to improve the STC rating of the wall then you can try using headsets. Here is the link.

Randy,

Thanks for the speedy reply.  Is it necessary that the soundproofing panel be adhered to the existing wall?   Would there be any significant sound reduction if soundproofing panels can be constructed to cover the entire surface area of the wall but could not be adhered to the wall (maybe hang the panels on a furring strip of some sort).  The panels would be butting up against each other so it wouldn't be a continuous seamless unit.   I am not looking to completely soundproof the wall, just something that would reduce the sound level of normal conversation from the neighboring unit to a barely audible on my side. 

What I'm thinking is to create a panel by putting MLV on one side of 5/8" sheetrock and placing that on the existing wall.  There would be no dead space between the existing wall and the panel.  I thought about using two sheets of sheetrock with MLV in between but it would probably be too heavy.  I slight variation would be to create dead space between the existing wall and panel but I don't know if this would reduce sound transmission any more than without the dead space between.

Would be curious of your opinions.

Thanks.

you can use sound absorbing panels for walls, class c sound absorbers for common areas of flats

This is a quite common problem, Normally to address this type of problem we would recommend MLV barrier with green glue and new layer of 5/8" drywall to increase the STC rating of the wall...to help BLOCK sound. MASS is what you need to reduce what your hearing, NOT absorption!
So here's the problem, in order to get a reduction you need to be able to completely seal(air tight) the perimeter of MLV at the shared wall.
