In terms of choosing the acoustic foam finest suited for your soundproofing requirements, an important consideration is no matter if to make use of a flat, plain-faced foam or even a profiled one. As we'll see under, you can find benefits and drawbacks to each and every. Get far more info about купить акустический поролон
What frequency?
One on the major variations amongst plain-faced and profiled foams is how they treat distinct frequencies. Low-frequency waves are longer and stronger, and consequently call for a thicker, a lot more robust foam. Plain-faced foam hasn't had any of the actual foam removed, and as such their absorbing qualities are significantly greater than their profiled counterparts. Accordingly flat, plain-faced foam is much better suited to soaking up low frequencies.
Consider of acoustic foam like a sponge and sound waves like water; a larger sponge will absorb more water!
However, sound waves incident at shallow angles and mid- to high-frequency waves have a tendency to 'glance off' plain-faced foams, meaning the sound isn't absorbed but only reflected. The right placement of the acoustic foam can mitigate this impact, although a profiled foam will help to catch and trap these pesky shallow-angle and high-frequency waves.
Beware of a prevalent myth that pervades when choosing a profiled acoustic foam; there's no distinction in soundproofing efficiency in between pyramid and wedge-shaped profiles!
What room?
We've had a look at frequency of acoustic waves you wish to treat. The space you would like to soundproof will also have an effect on which sort of foam is greatest suited for your needs.
As talked about above, the correct placement of acoustic foam can help to mitigate shallow-angle waves 'glancing off' your foam and getting reflected around the room. The organic acoustics of your room need to also be thought of. In the event the organic acoustics are very great, you may need to plump for any profiled acoustic foam, using it to tighten up the treatment of mid to high frequencies and fine tune the room's acoustic response, though you can also will need a solution to deal with these lengthy, powerful bass notes.
However if the all-natural acoustics of one's room are pretty bad, a plain-faced foam will provide you with that further bit of muscle to adequately cope with the treatment and absorption of incident acoustic waves for the preferred soundproofing effect. Consider once again of the sponge; a thicker sponge absorbs more water!
So which foam?
In terms of cosmetics, some people prefer profiled foam as opposed for the blank, homogeneous plain-faced option. Nevertheless, when it comes to functionality, the most beneficial solution is likely a mix of both plain-faced and profiled acoustic foams. With advice on installation from an skilled soundproofing skilled, it is possible to fine tune your solution using a mix of flat, plain-faced and profiled foams to handle a range of frequencies for quite a few unique applications.
