The Most Effective Way to Block Incoming--Or Outgoing--Noise L
SONEX Decibel Drop added to wallboard stops 10 times as much noise as wallboard alone.
Most American buildings have gypsum board (drywall) walls and
ceilings. Drywall is inexpensive and easy to work with, but it
tends to broadcast noise from room to room because it is stiff
and vibrates easily.
Many people deal with this problem
by adding another layer of drywall.
But this new layer vibrates, too--
resulting in little or no noise
reduction.
But if you install the same
sheet of drywall with SONEX Decibel
Drop Compound, you will wind up
with ten times the noise reduction. The reason? Decibel drop floats and
deadens your new layer of drywall,
sharply reducing noise transfer.
SONEX's tests show that if you merely add a new layer of drywall
to an existing wall, you will only get an extra 2 decibels of noise
reduction. But the same new layer of drywall, floating on our
Decibel Drop Compound, will stop 12 decibels more noise. 12 decibels is over 90% of the acoustical energy coming through the wall! 1
Anyone can use decibel drop in a weekend soundproofing
project. Simply apply 2-3 tubes to the back of a standard sheet
of drywall, press the drywall in place, and anchor it with a
few screws. You're done!.
