Industrial facilities include a wide range of applications like manufacturing, processing plants, construction sites and more. The typical sound problem in most industrial applications is the need to lower the overall level of sound or lower the decibel level of specific machinery. Machinery can include punch presses, printing equipment, crushers, grinders, air tools, drills, jack hammers, pumps, etc. The noise generated by these machines not only fatigue operators but may not meet OSHA safety requirements or other local noise ordinances.

To lower the sound level of these machines, the best course of action is to create a sound proof enclosure around the source of the noise. This will eliminate noise and prevent sound from permeating into the rest of the facility or neighboring areas. There are many ways to accomplish this, however, most methods will require some type of massive and/or dense material and possibly the addition of a fluffy absorptive material.

To create sound proof enclosures, you may wish to consider using a combination of the following materials:

BlockAid Sound Barrieris amass loaded vinylused in composite structures to add mass and aid to increase the STC (Sound Transmission Loss) of a system. This material weighs one pound per square foot, ships on rolls and can be easily cut with a utility knife.

Alternatively, like in the image at the top of the page, a machine or enclosure can be lined with acomposite foam. This material has a layer of thevinyl sound barrierfloating between two layers ofacoustical foam. This material combines a layer of massive/dense material (vinyl sound barrier) to block sound with two layers of absorptiveacoustical foam. Suspending thebarrieras a limp mass between the two layers ofacoustical foamdecouple it from the existing surface of the enclosure, improving its effectiveness.

In addition,StratiQuilt Blanketscan be installed on-site around machinery to reduce the mechanical noises. Thesequilted fiberglass blanketscan be manufactured with or without abarrier septumand available with grommets for hanging. Optional outdoor coverings can be quoted when the material requires UV protection.
