Acoustic
Sciences introduces the IsoDeck System, a non-rubber answer to deck
isolation. While rubber has long been regarded as an excellent isolator,
its density under load actually transmits sound. At ASC, the industry
leader in small room audio acoustics, our goal is to improve your
room acoustics. We engineered our IsoDeck with a technical woven
high density felt, the only isolator that won’t transmit sound.
Plus, we don’t stop with just floating the deck on felt. We
add WallDamp, a visco-elastic damping material that stops vibration
cold. What you get with the ASC IsoDeck is superior isolation plus
vibrational damping.
How it Works
The natural process of sound vibration creates
friction and unwanted energy buildup through the bending and slipping
of adjacent surfaces. This in turn causes the floor to add unwanted
acoustic coloration to your room. The IsoDeck isolates the floor,
using a unique high density 1” felt strip called a slot loaded
spring, inserted into the bottom of every joist to float the deck.
The felt is lightly glued into a 3/4” x 3/16” rabbeted
groove. Joists can be 2 x 2, 2 x 4 or 2 x 6.
The
top of each joist is covered with strips of damping polymer called
WallDamp. Two layers of subfloor rest on the joists, separated by
squares of WallDamp. With this system, even high power sub-bass
energy is isolated and rapidly dissipated. You get real sound isolation,
reduced floor resonance, and damping even when there’s thunderous
sound.
Why not Use Rubber Supports?
Consider
your room as a giant guitar body. It resonates at certain sound
frequencies, noticeable only when the volume is turned up. The floor
helps to propagate the room resonance, so we want to isolate it
with a deck. Rubber feet transmit sound, causing the deck to bounce
which in turn causes acoustic problems in your studio or home theater.
Conversely, the ASC IsoDeck floats on technical felt which doesn’t
transmit sound, there is no resonance. This in turn actually improves
room acoustics while effectively isolating sound.
True isolation is critical to getting an accurate
mix. Engineers wishing to avoid trouble down the road should seriously
consider an ASC IsoDeck in their control room.
