How to Install Super Soundproofing Anti-Vibration Isolation Pads
Many types of machinery may require super soundproofing anti-vibration isolation pads. Sound produced by machinery falls into two categories: Vibration sound and airborne sound. Isolating vibration is one means of soundproofing many types of machinery. This is accomplished by using a commercially available product which consists of a neoprene pad of high quality which has a ribbed elastomeric outer layer. This layer has a special compound which resists aging, water, oil and compression set. The pads are constructed using cross ribbing with alternating rib heights and utilising a cork center to provide extra sound isolation. The rated maximum load capacity of each of the cork center pads is 50 pounds / sq in. The pads may also be stacked to increase the capacity and isolation. For example a two inch pad will support 200 pounds.
Step 1 – Using On Drywalls
Choose the size of pad according to the bearing weight, not for the footing size. The best pads for sills of 2 X 4 used for wall studding are the 3 inch pads. They should be placed under the studs or placed approximately two to three feet apart underneath the sill depending on the wall load. The two inch by three eighths inch neoprene pads without the cork may be used to support the edges of the drywall panels. All of the cork center pads are about seven eighths of an inch thick. The pads are available in a variety of sizes to suit most applications.
Step 2 – Using On Machinery
When isolating walking, vibrating, lively machinery, for instance washing machines, use rubber furniture cups stuck to the pads with household adhesive. The pads are placed under the four corners of the machine. If the machine produces a lot of noise, or the floor is not absorbing the vibration, a Mass Loaded Vinyl mat may be deployed under the machine, protruding a foot or so around the machine. This may be used in addition to the anti-vibration isolating pads. For a treadmill, the pads should be placed under each corner of the machine. The isolation pads may be cut into appropriate sizes for the machine being soundproofed. They may also be doubled up for use on very heavy machines. To counter uneven wear on the pads, they may be repositioned or rotated underneath the machinery.
Step 3 – Other Appliances
Dimple pads are available to absorb the vibrations created by running and exercise machines. They are specially designed to cut down the sound and the vibration of a machine preventing them from being transmitted through the floor and into the ceiling of the room below them. Speaker enclosures and TV sets placed on the isolation pads do not transmit a lot of vibrations into the floor of a room. The isolation pads have been used successfully to dampen the vibrations from a roof mounted air conditioning unit by placing a pad under each corner of the unit.
