6 FAQs about [Generator fresh wind attenuator]

How does sound attenuation affect a generator?

Any amount of sound attenuation applied to a generator set will alter the noise produced by the engine and yield a more tolerable deadened sound characterized by a rush of air rather than a mechanical or fan noise of a high-speed diesel or gas engine.

Will a sound attenuated enclosure work with multiple generator sets?

When sizing multiple enclosures for more than one generator set, whether it is a sound attenuated or weatherproof enclosure, it is advisable to make a decision based upon the worst case data so that the sound attenuated enclosures will work with all generator sets considered for the project.

How does a sound attenuation system work?

The most commonly used attenuation systems rely on isolating the generator from workers and the public alike with a sound-attenuated canopy or enclosure - a housing which allows the generator to get the air it needs to run and to carry off its filtered exhaust, but which also deadens the vast majority of the sound the machine makes in operation.

How do I choose a sound attenuation enclosure system?

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 enclosure will be. The effect is most directly correlated with kW rating and air flow needed for the generator.

How do attenuation housings work?

In addition to simple sound muffling, many attenuation housings also use active and reactive silencing systems to further eliminate harmful or unpleasant levels of noise that the genset may produce. One important thing to understand is that each generator engine produces a unique sound profile.

How do generator set manufacturers design sound-attenuating enclosures?

Generator set manufactures use these concepts when designing sound-attenuating enclosures: Acoustic Barrier – Enclosures constructed of steel panels. Electrical, fuel pipes and any other auxiliary entries must be sealed. Acoustic Insulation – Sound absorbing insulation in/on interior panels.
