The Way to Reduce the Noise of Air Compressor

With the noise of an air compressor significantly reduced or nearly eliminated during each operation, a lot more work can generally be accomplished, especially if other people are involved in a given project. In a workshop setting, for instance, the reduced noise levels allow you to hear your work colleagues as each application is applied with the tools that connect to the machine. If someone has a question that pertains to the work at hand, the answer can be given as you demonstrate, the compressor won’t have to be shut off in order for you and your coworkers to hear one another.

While the use of a soundproof enclosure is the most effective way to eliminate compressor noise, the roaring decibels can still be adequately reduced with the use of sound blankets, which muffle volume by absorbing the high and mid–range frequencies. When draped across walls within an area that contains a compressor or other loud piece of machinery, the frequencies are comfortably reduced for those on the outside. As such, sound blankets have become a popular anti–noise aid in home recording studios and band rehearsal spaces, where amplification is absorbed by the blanket fibers and thus blocked from other parts of the house and — more importantly — the ears of neighbors.

With dental air compressor, sound blankets can be used in several different ways to absorb noise, especially from the noisiest part of the machine: the piston cylinder. One way to use sound blankets is by placing them on the inside of a two–sided enclosure that consists of two walls hinged together at a 45° angle. Place the compressor in the far–back corner of your garage, and seal the area off with the blanket–buffered enclosure. This should reduce sound to a level that will barely register with anyone in your living, or for that matter people in other houses nearby. The two–sided enclosure method is good for both portable and stationary compressors.

Another way to seal off compressor noise with sound blankets is by placing the machine inside a large cabinet or box, and then draping the blanket over the outside. For example, a small horizontal compressor could be sat down inside a box or even a chest with the blanket placed down over the top and sides like a tablecloth. Within a sizable cabinet, a portable compressor could be placed in side with the blanket draped over the closed door.

The most effective way to minimize the noise of a smaller, home-use air compressor is to place it inside a soundproof enclosure during times of operation. When cut to the right measurements, an enclosure can be made by hand with the right boards and foaming material. For example, a horizontal portable compressor could be placed inside a handmade box constructed of 12 mm medium density fiberboard. For maximum effect, the walls should be double–plated for a total board thickness of 24 mm, in addition to a layer of inner–padding consisting of convoluted foam board.
