Generator air intake and exhaust noise reduction

When sound waves are produced they are naturally reflected when they hit a hard surface. Installing an absorption surface over hard surfaces in most generators can reduce some of the reflected sound. In a room with hard surfaces, soft materials such as absorbent ceiling panels, floor rugs or carpeting, and blinds or. . The most common device used to muffle noise from generators is acoustical enclosures. Typical sound attenuated generator enclosures. . When there is no specific decibel level to be met at a given distance then it is common to provide a performance specification; that is to specify only the amount of attenuation required by the enclosure itself. Most. . The most overlooked aspect of choosing a sound attenuation enclosure system is that the as the amount of sound attenuation increases, ie the quitter the unit becomes, the larger the generator. [pdf]
