|| Sound Deadening Board
What is sound deadening board (AKA “soundboard”)?
“Sound-deadening board,” sometimes referred to as “soundboard,”
is a building material often used as an additional layer in the
construction of soundproof walls, ceilings, and floors to reduce
the transmission of sound.
Soundboard can be used in conjunction with soundproof drywall (also
known as “sound engineered drywall” and “soundproof
sheetrock”) or in conjunction with regular drywall to achieve
a soundproofing effect.
How does sound-deadening board block sound?
Sound-deadening board blocks sounds in the following three ways:
by increasing the space between the sound’s origin and the
other side of the wall, ceiling, or floor; by adding mass to the
conducting surface and by dampening or “absorbing” the
Adding mass, space, and dampening are the three ways sound can
be blocked. The principle of adding space is relatively easy to
understand – the further one is from a sound, the less likely
one is to hear it. The principle of mass is also simple –
add layers through which the sound wave must travel before reaching
the other side of a wall, ceiling, or floor, and more of the sound
waves will be absorbed before they have a chance to become audible
outside of the room from which the sound originated. Finally, the
principle of dampening involves reducing a sound wave’s ability
to vibrate, thereby reducing its ability to become audible. Dampening
a wall (or floor or ceiling) is also known s achieved by disconnecting
the wall, which is achieved by adding layers that obstruct the path
of the sound wave. Sound deadening board employs all of these principles
in blocking sound.
How is sound-deadening board used?
Sound-deadening board is often applied between sheets of drywall
to form a sandwich. A special type of glue must be used to connect
the sound deadening board to the drywall; however, there are some
new materials on the market today that are very similar to sound
deadening board but do not require the use of glue. Overall, using
sound deadening board to soundproof a room is a cost-effective way
to reduce noise.
