Generator silencer container

The key to soundproofing your generator box is to add layers of free space that dissipate the sound. Ideally, you should add at least two layers of soundproofing material as an effective way on how to quiet a generator. To make your generator box soundproof, the first layer you should add is a Mass Loaded Vinyl (MLV).

Ideally, you should add at least two layers of soundproofing material as an effective way on how to quiet a generator. To make your generator box soundproof, the first layer you should add is a Mass Loaded Vinyl (MLV). This material acts as a sound barrier. It is made from vinyl and is supposed to block the sound generated by any device or machine.

In theory, you could use vehicle sound deadening mats instead. They're made from butyl which is a type of Vinyl. It's quite a dense material and so can add mass to the structure. But I'd probably steer clear of them for a generator quiet box in most situations.

You can enclose a generator to make it quieter, providing you use soundproofing materials. In short, you'll want to block, dampen, and absorb sound waves before they reach your home or RV. A box by itself won't make much difference. The important things are the materials you use in it.

As for noise reduction results, there's not really a concrete answer. With the right soundproofing, you could expect a reduction of up to 20dB. I won't include the necessary quantities to build a soundproof generator box, as it depends on the size of your generator.

Anyone who has used a generator knows they can be extremely loud. If noise pollution is one of your primary concerns, shop for a soundproof enclosure. Noise-protective enclosures shield your team members from the generator's loud noise. Long-term exposure to loud noises can result in tinnitus and even permanent hearing loss.
