Title: Isolation tape on alternating studs?
Post by: benstephen on September 02, 2015, 06:39:45 PM
Hi.  I have read the following and am wondering if there will be any noticeable reduction in a room used for loud band practice.  If this method of isolating the two sides of a wall will make a difference, then I will go buy some camping mats from Walmart and glue strips of them on the studs before I hang the drywall.

"How to “Stagger-Stud” and soundproof existing stud walls using Sound Isolation Padding Tape: Assuming the wallboard has been removed and the studs are exposed- Apply 2 layers of the green 1/8″X1-7/16″ tape to every other stud. This will build out the stud by about a 1/4″. The tape has a peel-off backing and may be cut with scissors. Place your wall panels over the studs and fasten them only to the studs which have the tape. If the other wall is open do this to it also, alternating the studs, that is, do not apply tape to studs which have tape on them already on the other side. This system breaks the sound path through the studding and is very effective and inexpensive for reducing sound transfer through the wall. If you don’t do anything else, do this! It can improve the sound reduction of your wall, especially at speech frequencies. "

Thanks, Ben

Some more info:  The mats I was going to buy to use for these isolation strips are closed cell foam.  Is that the right material if I go ahead with this plan?  The outside of the walls will have a layer of 3/4 OSB and the inside will be two layers of 5/8" x rated dry wall.  studs are 2x4 24" OC with R13 batts.  Thanks again.

That is known as "The poor mans soundproofing"  which is fine in certain situations. However for band practice is not one of them...It would be better to either use clips and hat channel or build the room in a room (ie double wall construction).
After you have made that decision you are most likely going to have to add more mass to the wall...

Minimum starting point for these systems are 8 lbs sqft and I have done some as high as 25 lbs sqft...

Decoupling system is to break the path of vibration (low frequency) but you still have to increase the weight...

What are you expecting for results?? this is kind of the starting point.. 100 db inside and 70 db outside? or do you need it quieter?

Thanks Randy.

100db to 70db would be pretty good.  I don't care if the neighbors can tell the band is practicing, but currently it is just unbearably loud out at the street.  It's a 3 car garage and we are enclosing the 3rd garage space, including building a wall in front of the roll up garage door.

Ok add a second layer of either 5/8" sheet rock or 1/2" cement board in between the studs against the OSB with 1/4" notch trowl and construction adhesive...minimum screws.
Seal perimeter of all inserts and seams with acoustical caulking to increase the outer mass..

Insulate cavity completely the add a layer of 1/8" mass loaded vinyl tape and caulk air tight.

Chose your decoupling method.

Finish with double 5/8" with green glue in between.

Make sure you handle the room supply and return so you guys can breathe..

Feel free to call me direct

Will doing all of this get me just down to 70db?  This is a budget buster :(

Yes or quieter!
