Not only do screw air compressors
power important manufacturing elements and power applications, but the heat generated by the compressed air process can also be used as a by-product to offset other energy costs, such as heat recovery. However, there is another form of energy that results from the compression of air - sound.
The sound we hear and the volume we hear depends on the proximity to the source of the sound, as well as other variables in a particular environment. When indoors, these variables can include the size of the room, the things in the room, and the ability of the various surfaces in the room to absorb or reflect sound. When a sound wave comes into contact with a surface, a portion of the sound wave is absorbed by the surface and another portion is reflected back. How well a surface absorbs sound depends on its material - think, for example, how different a room with carpet might sound than a room with tile or hardwood floors!
The benefits of reducing compressor sound levels.
Do you know the volume of the various sounds you hear every day? Sound levels are measured in decibels. Here are some common noises we hear every day and typical associated decibel levels:
Compressor sound levels range from 40-92 decibels, and any noise above 85 decibels is considered harmful. This means reducing the noise from screw compressors and compressed air systems not only makes the workplace more pleasant, but also healthier and safer for workers!
The size of the compressor room, the location of the compressor in the room, and the associated materials of the compressor room are all important variables in generating (and reducing) compressor noise. Vibration transmission through compressed air ductwork also affects sound transmission throughout the facility. That's why installing proper vibration and sound insulation in compressors and ductwork, or even partially enclosing ducts with sound absorbing materials, helps keep noise to a minimum. Many stationary screw air compressors are also equipped with integrated noise reduction devices.Air compressor manufacturers
