There is no Substitute for an Expertly Engineered Acoustic Enclosure

Over the years, many businesses have endeavoured to create a soundproof room or acoustic enclosure by soundproofing walls and attempting to carry out their noise-cancelling acoustics.

As a result of this, many myths have sprung up about soundproof rooms and plant enclosures which Flexshield – Australia’s industrial noise control specialist – would like to address immediately.

The first of these myths is if you line an enclosure or plant room with foam, it will drastically reduce noise.

Unfortunately, this is not the case, because the sound from a source within an enclosure is made up of direct (non-reflected) and reflected (reverberant) sound, lining the walls, windows and doors with foam, mineral wool, corrugated cardboard will make little difference.

It may reduce the level of reflected sound but will have little to no impact on the direct sound, and it is this that controls the sound level of the plant or machinery.

The second myth is to put a hole in the wall to let the noise out.

Some people think that if you cut or drill an opening in a plant room facing away from the generator or whatever plant you are trying to silence, this will reduce the noise in the area you want to protect.

Once again, the overall sound will be a combination of direct and reflected noise.

Yes, the reflected noise will reduce marginally. However the overall decibel levels will remain high, and of course, you will now have noise egressing from the second opening, thus defeating the purpose.

The third myth is to arrange it so that the plant room or enclosure faces out to a thick hedge or strand of trees.

It’s easy to see why people might think that, given that thick foliage does slightly attenuate sound especially when it’s windy but mostly it’s merely a case of “out of sight, out of mind.”

For trees and shrubs to work as a soundproofing method, they need to be lush and thick and tens of metres deep!

Plus if the leaves are particularly dense, flat and broad-leafed, high-frequency sound can be deflected back.

When you consider that even a small solid building may only provide around 15dB screening attenuation, what chance does a shrub have!?

Flexshield present and dispel these myths to prove to you that there is no substitute for a professionally engineered Acoustic Enclosure.

Our acoustic engineers have ensured that the sound absorption and noise reduction qualities offered by our enclosures are as high as possible.

The purpose-designed enclosures can also meet your needs for access, maintenance, lighting, ventilation, extraction and aesthetics, ideal for a host of industrial applications such as enclosures for generators, compressors, pumps, saws, presses and other heavy-duty machinery. They can be custom designed and manufactured using our patented panel “Sonic System” or pre-fabricated in-house with structural frames.
