Sheet Metal Noise Damping

Because the stiff materials keep the damping material constrained in the face of vibrational energy cld reduces impact noise.

Sheet metal noise damping.

This vibration damping material will dramatically reduce vibration energy that would normally be stored in the walls of the cabinet. Road noise includes the sound of your tires on the pavement and potholes or uneven surfaces which cause vibrations. Noise control products we design and manufacture bespoke noise control elements to solve specific noise problems. Our noiseless steel is a sandwiched steel panel consisting of two sheets of metal with a visco elastic inner layer that results in a metal plastic metal mpm panel.

Vibrating metal is a common noise problem in industrial and commercial environments and one that companies must often take into consideration. Sound deadening reduces sheet metal vibrations and road noise. You can reduce interior noise levels 3 10 db by applying vibration damping material to the door panels firewall floor pan trunk lid or any interior sheet metal panel. Quiet equates to quality in any application and pmi s acoustically designed panels help reduce noise and vibration by damping structure borne noise insulating against air borne sounds and damping inherent vibrations.

Like extensional damping cld converts vibration to heat but this type of damping utilizes a layered construction with a viscoelastic polymer sandwiched between two sheets of a stiff material such as a metal. Thin metal parts and structures can transmit noise when impacted or by natural resonance when excited by acoustical energy. Provides a cost effective sound proofing solution. The most common culprits of sound inside of vehicles are road noise and vibrating sheet metal.
