In relation to choosing the acoustic foam greatest suited for your soundproofing specifications, an important consideration is no matter if to use a flat, plain-faced foam or a profiled one. As we'll see below, you will find benefits and drawbacks to every. Get extra data about купить акустический поролон
What frequency?
One of your most important differences amongst plain-faced and profiled foams is how they treat various frequencies. Low-frequency waves are longer and stronger, and because of this demand a thicker, far more robust foam. Plain-faced foam hasn't had any in the actual foam removed, and as such their absorbing qualities are significantly greater than their profiled counterparts. Accordingly flat, plain-faced foam is greater suited to soaking up low frequencies.
Believe of acoustic foam like a sponge and sound waves like water; a bigger sponge will absorb more water!
On the other hand, sound waves incident at shallow angles and mid- to high-frequency waves have a tendency to 'glance off' plain-faced foams, which means the sound isn't absorbed but only reflected. The appropriate placement of the acoustic foam can mitigate this effect, while a profiled foam will help to catch and trap these pesky shallow-angle and high-frequency waves.
Beware of a typical myth that pervades when deciding on a profiled acoustic foam; there is no difference in soundproofing performance between pyramid and wedge-shaped profiles!
What room?
We've had a look at frequency of acoustic waves you need to treat. The space you need to soundproof may also influence which kind of foam is most effective suited for your needs.
As described above, the correct placement of acoustic foam can help to mitigate shallow-angle waves 'glancing off' your foam and being reflected about the room. The all-natural acoustics on the room need to also be thought of. In the event the all-natural acoustics are fairly great, you may need to plump for a profiled acoustic foam, using it to tighten up the treatment of mid to higher frequencies and fine tune the room's acoustic response, while you can also need to have a solution to cope with those long, powerful bass notes.
However in the event the organic acoustics of the room are quite bad, a plain-faced foam will provide you with that added bit of muscle to effectively cope with the treatment and absorption of incident acoustic waves for the preferred soundproofing effect. Assume once again of your sponge; a thicker sponge absorbs extra water!
So which foam?
With regards to cosmetics, some people choose profiled foam as opposed for the blank, homogeneous plain-faced option. Even so, when it comes to overall performance, the most effective solution is possibly a mix of each plain-faced and profiled acoustic foams. With tips on installation from an seasoned soundproofing expert, you can fine tune your solution using a mix of flat, plain-faced and profiled foams to deal with a variety of frequencies for quite a few diverse applications.
