A Constrained Layer Damping
natural process of sound vibration creates friction and unwanted
energy build-up through the bending and slipping of adjacent
surfaces. WallDamp is a thin sheet of material designed as
a damping interface between joined surfaces undergoing vibration.
As a result, when it's placed between the bordering surfaces
there is maximum damping action on vibration. WallDamp uses
an energy absorbing polymer to convert the sliding action
into a shear stress whose energy is rapidly dissipated. This
increases the sound isolation, reduces wall /stud resonance,
and dampens tympanic wall thunder. For advanced sound and
vibration control projects, nothing works better than our
Iso-Wall constrained layer damping system.
Vibrations - Vibrational energy is stored for a long
period of time and can be retransmitted through other mechanisms.
Example: an undamped room wall can vibrate perceptibly for
more than one second when excited by sudden sonic impacts.
This vibration then becomes a secondary source of sound emitted
back into the room, creating a source of unwanted lingering
noise. This is highly contrary to the desired acoustics of
a well-developed sound room.
Damped Vibrations - Vibrational
energy is removed quickly, usually through frictional losses,
and is no longer available to be transmitted. Example: a damped
room wall will vibrate for an imperceptible length of time
after being excited by sudden sonic impacts. This means that
there is no secondary radiation of unwanted noise. This is
the desirable situation for preferred sound room acoustics.
The Iso-Wall system is being offered as an integrated
package -complete with pre-damped resilient channels, damping
gasket, bearing felt and acoustical sealant.
