(Video) Soundproofing - June 2nd 2015
What is the proper method to sound proof over a gyproc wall to reduce noise from the neighbours TV?
In order to soundproof walls you must add a sound barrier to the inside of your walls. You must be prepared to lose some floor space on the walls.
1. Add 1/2" sound board or donna conna board to inside wall.
2. Install acoustical channel from ceiling to floor spacing 16" apart, screwing into the studs.
3. Screw 1/2" drywall to acoustical channel. This method will add 1 1/2" to inside of wall. If there is a severe sound problem between rooms (ie: music rooms, etc.) you should consider adding another 2 x 4 wall on the inside full of R-14 sound insulation such as Roxul Safe & Sound insulation. This should be installed 1/2" away from existing wall then complete with steps 1 thru 3 the overall wall thickness requires 5 1/2"
Note: A Product made by Dryco, called Quiet Rock, is available across Canada. This is a drywall that can be installed right over the existing and will reduce the sound transfer by roughly 75%.

1. Block off all forced air heating ducts (stuff with fibreglass batts in plastic bags) into basement suite and install convection heaters in the suite.
2. Install R20 Batt insulation up tight against the upper sub floor plywood (install around electrical wiring).
3. Apply Donna conna board or sound board to the bottom of the floor joists.
4. Apply Sound Bar (Resilient Channel 16” centres over Donna conna).
5. Apply 5/8” drywall to sound bar, tape and fill.
NOTE: If your home is forced air heat, it is advisable to use an alternate heating source for the basement to stop transfer of sound up through the duct system. This is done by terminating your ducts into the basement area.
It’s just that easy!
