When it comes to picking out the acoustic foam ideal suited to your soundproofing specifications, an essential consideration is irrespective of whether to work with a flat, plain-faced foam or even a profiled one. As we will see beneath, you can find benefits and drawbacks to every. Get extra data about купитьнаборы акустического поролона
What frequency?
One from the most important variations involving plain-faced and profiled foams is how they treat diverse frequencies. Low-frequency waves are longer and stronger, and consequently need a thicker, much 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 superior suited to soaking up low frequencies.
Assume 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 possess a tendency to 'glance off' plain-faced foams, meaning the sound is not absorbed but only reflected. The correct 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 typical myth that pervades when deciding upon a profiled acoustic foam; there is no difference in soundproofing functionality amongst pyramid and wedge-shaped profiles!
What room?
We've had a look at frequency of acoustic waves you should treat. The space you should soundproof will also impact which type of foam is best suited to your specifications.
As described above, the proper placement of acoustic foam can help to mitigate shallow-angle waves 'glancing off' your foam and getting reflected about the room. The natural acoustics of your room need to also be deemed. When the natural acoustics are really great, you could choose to plump to get a profiled acoustic foam, using it to tighten up the treatment of mid to high frequencies and fine tune the room's acoustic response, despite the fact that you will also have to have a solution to handle those long, strong bass notes.
Alternatively in the event the organic acoustics of the room are fairly bad, a plain-faced foam will give you that additional bit of muscle to appropriately cope with the treatment and absorption of incident acoustic waves for the desired soundproofing impact. Feel 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 towards the blank, homogeneous plain-faced option. Nonetheless, when it comes to functionality, the very best solution is almost certainly a mix of each plain-faced and profiled acoustic foams. With guidance on installation from an skilled soundproofing professional, you can fine tune your solution using a mix of flat, plain-faced and profiled foams to handle a variety of frequencies for quite a few distinct applications.
