drywall

Hey guys, first timer here, great website. I have a small room with half inch drywall, no inso. My idea is to blow inso into wall via a hole in the top of wall between studs, then apply another layer of 5/8 drywall. Would this make a big difference in the way the room sounds now?? Or maybe go with this fiber stuff sound board i saw at home depot then drwall over that? Also, 8) should I glue the drwall and not use nails ?? Thanks a bunch

We will probably need more info from you. If your object is to make it quieter inside to record vocals and soft acoustic sources, then yes , putting insulation in the walls and a second sheet of 5/8ths will help with sound transmission some. but if you are asking if it will do anything for supressing the sound transmission of a guitar amp through the wall or the sound of a lawnmower outside migrating through the wall, then I say it won't help very much. As for your question as to whether it will make a big difference in the way the room sounds... no it wont. To change the "sound of a room, you need to be looking into sound absorption ideas . Beefing up the walls basically serves to "Sound Proof" your room , meaning it will deal with the sound trying to get in and out of the room. The acoustics of the room sound are dealt with by wall design and sound absorption. Let us know more of what your goals are for the room. Tom

Wow, thanks for the quick reply, OK, room is 11 x 17. It's mainly for drums. I record guitars and bass direct to avoid bleed through on drum mics. I DO want to suppress the sound sound and make it more energy friendly at the same time. During summer here in AZ. it gets hot. So I guess as far as room accoutics, I will have to address that afterwards. Big thing now is over all keeping the nieghbors happy and a more energy efficient. Thank a bunch.

In addition to following the forum guidelines linked by Keith, a correction - Tom, actually changing your walls WILL change the room sound - single 1/2" wallboard on studs acts as a panel bass absorber. Either adding more mass to its surface OR filling with blown in insulation will CHANGE that panel absorber - the insulation will widen the "Q" of the trap as well as lessen the effect, and additional mass on the studs will lower the effective trap frequency...

I thought it would make a pretty big impact on the way it sounds now. I'm going to do both, blow in inso and a layer of 5/8's, also take out the door and put in a nice slider. That would help alot for sound transmission and accoustics inside. I mix and record in the same room.

I stand corrected! Thanks Steve, I had not thought of that. Tom

While I agree that crap hollow doors are, uh, crap, I disagree that a dual pane glass sliding door is superior to two solid and heavy doors with excellent seals, one on each leaf. Study up more on what constitutes a leaf. 8) --Keith :mrgreen:

you might be right, but, the room I have will be better off not having doors open up into it. Also I have seen both types of doors in big studios. peace.
