Low frequency/bass reverberations
« on: March 15, 2010, 05:14:02 PM »
I would LOVE some help with this issue....I have a new neighbour (shared common/living room wall in townhouse) and he is addicted to his entertainment system.  He was very responsive as far as turning teh volume down.  The problem is that the lower frequency and/or reverberations still come through!!  I have looked into contacting local contractors in my area to install soundproofing, but I am unclear as to whether or not soundproofing will help at all in this matter.   

Any insight available at all please?  I have long since realized that if its a choice bewteen peace of mind or money, I'll spend the money for the ability to relax in my home.

Thanks all....

There are somethings you can do with the shared wall, however you WILL always have the "Flanking Noise" from the ceiling and the floor since you continue to share direct connections in these areas.
You should use cotton fiber in the cavity, staple and seal MLV, decouple the wall with clips and channel, add your double 5/8" drywall with Green Glue sandwiched between.
You can evaluate your "Flanking Noise" and if need be address those areas as well. You might still hear the "Thump" from the low bass. Make sure your neighbors speakers are OFF the ground.

Thank you for the response.  I have a contractor proposing to do the following:

**wall:Install Blow-in R-13 value cellulose insulation 110sq ft.  Install new frame 2"x 4" stud,R-13 insulation,sound barrier boards,blueboards and plaster 110sq ft.**


I am doing as much internet research as I can but still dont understand everything I'm reading.  Will this proposed work address the problem as much as applied/installed insulation can?   Or do you see little to no value added from this work?

Blown in cellulos is a waste of time and money, the new wall is in the right direction make sure it does not touch existing wall and use isolation padding tape where the new wall meets existing structure and on the stud face before you hang blue board. Use the cotton fiber insulation R19, no sound board, double blue board with green glue and make sure you leave a perimeter gap filled with caulk this way the "Flank" doesnt end up back on your new wall.

Feel free to contact me direct my info is below.

Thank you, I will be in contact soon.  Are there any installers/experts you could recommend in the Boston (Middlesex) area?
