soundproofing basement ceiling above music room
Hey all - I've got a band practice room in my basement. It's all digital stuff, run through a PA so we don't have booming bass or acoutstic drums. Effectively, it's exactly like just playing a CD through a very loud PA.
The basement is finished with a drywall ceiling.
The first floor right above it is carpeted. You can definitely hear the sound up there - but it's actually not too bad.
Go up to the second floor where all our bedrooms are - and the sound becomes more faint. You can't sing along with the song - and really can only hear some occasional lows/thumps and the beat. It's definitely not enough to wake somebody up - but is just barely enough to make it annoying.
The ceiling above the band space is not insulated since it's interior. So I'm wondering if I could cut some holes in the ceiling drywall and have insulation blasted in. It's also a tray ceiling with soffets for the HVAC. Somehow it would seem to make sense to blast that full as well.
However - I know there is a void there. And I thought voids did a good job deadening sound as well. Maybe insulation really wouldn't make a difference.
I want to avoid using the foam acoustic tiles on the outside for asthetic reasons.
You can try roxul insulation.
If it is lows (bass) you will never eliminate those frequents without a complete gut and sound isolation room. If it was me I would just buy green glue and add a 2nd layer of drywall, or if you have money to burn Green glue then a layer of quiet rock
