reducing noise transmission in an open concept house
« on: February 05, 2011, 04:44:11 AM »
We've moved into a 2-storey house; the basement and 1st floor are open concept. Ventilation and heating needs preclude walls between the 2 levels.
The basement contains the washer, dryer, and a TV area. We have 2 problems: The TV's sound invades the 1st floor, and when turned up overwhelms it.
How can I reduce sound transmission? Could I build a folding screen for the washer&dryer? If so, should I use glass-wool insulation (6pcf)? Could I make the screen out of 1/2-in plywood and MLV?
To reduce transmission btwn floors, could I use moveable panels or a curtain around the three open sides at the bottom of the stairs? The panels could be on wheels, or I could put a hospital-curtain type of track on the ceiling. If I made curtains, would I use MLV & sound-absorbing batting on 1 or both sides? (but nothing attractive to dust mites)

You could do a band-aid approach like you mention, which would deliver minimal results or you can control and contain the noise issue to achieve a greater reduction.
Portable panels and/or curtains only do so much because you still have free path or air in motion. Hard lid ceiling and solid doors to create and airtight room will deliver the best bang for buck!

That, alas, is the problem. Until and unless we can solve the heating and ventilation problems that would result from filling in the walls and building a door at the bottom of the basement stairs, we can try only to _reduce_ the noise transmission. If I can reduce the noise from the washer & dryer, husband won't turn the TV way up. If I can decrease transmission between floors, or reverberation on each floor, his TV and my radio or stereo are less likely to interfere with each other (I hope).

if you are to try something like that than you would need to have 4 sides and a top for the washer and dryer...if you just do a curtain or a 4 sided noise panel you will focus all the sound up into the floor ceiling system and if you have open joist than you might not see much of a change.

What is on your floor upstairs? carpet or wood floor?

for the free path up the stairs the portable panels would work well... floor to ceiling for the height.
