ENVIRONMENTAL CONSIDERATIONS — dB(A)
Acoustic Material
Consider the following when selecting acoustic material:
1.DO NOT use fiberglass as an acoustic material. Fiberglass is a poor selection of acoustic material because of its low density, poor flame retardant, and poor cleanability.
2.Foam is least likely to deteriorate due to abrasion and has good aesthetics. However, foam is difficult to clean and not all foams are fire retardant.
3.A concrete block enclosure is an excellent barrier in regards to noise reduction. The blocks may be filled with sand to make the wall more dense. However, concrete housing tends to become hot and superior cooling methods will be required for proper engine performance.
