Are you looking for some sound absorbing material? Here we list and comment on the characteristics of the main boards or boards that are commercialized

sound absorption plates

Today, soundproofing and sound absorption are more of a necessity than a luxury. We live surrounded by noise and we need to reduce it. One of the main resources to do this in garages, music studios and buildings or rooms in general are the sound absorption plates.

You need to do a little bit of precision. Materials with acoustic insulating properties reflect sound, while sound-absorbing materials absorb them. This is a technical difference, which in many cases is not taken into account and the materials are used interchangeably.

It is common for installation to be carried out on a false ceiling, although this is not always the case. Sometimes it can be fixed directly to the ceiling or the wall.

Sound-absorbing plates board materials

There are different materials with which sound-absorbing plates can be made. One of them offers different benefits and results when it comes to soundproofing a wall:

  • Sound-absorbing flexible polyurethane foam. It is an inexpensive material, with many customization options, designs and textures, very easy to install (in most cases only with adhesive) and offers a good result. In most cases, when talking about sound absorption plates, this type is referred to. Although this is a bad generalization.
  • Wood and wood products like particle plates covered with melanin.
  • Gypsum plaster. This is another common feature that also helps to correct the reverb time. Its use is exclusively internal.
  • Polystyrene. It is also a plastic polymer like polyurethane. In its expanded version it is used as an acoustic insulator, although it is more sought after as a thermal insulator.
  • Rock Wool. In addition to offering excellent sound insulation, it is also not a combustible material. It is easy to maintain and is an environmentally friendly material.
  • Glass wool.

One of the criteria that many tend to ignore when choosing acoustic cards is the issue of fire. In the event of a fire, some of these acoustic insulation systems may not provide the best performance. For example, polyurethane foam offers good insulation at a good price, but its use is not recommended in areas with a “fire risk”.
