What is an acoustic board?
An acoustic board is a special kind of board made of sound absorbing materials. Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, the intensity of sound decreases when sound passes through an acoustic board. The production of heat energy balances the loss of sound energy.
They are applied in a wide variety of spaces such as halls, seminar rooms, auditoriums, libraries, courts, music production studios and so on. Placing acoustic panels on walls or ceilings is the best way to eliminate echo, reverb and reduce overall ambient noise in any room. Sound waves reflecting off walls cause most of the sound issues. Therefore strategically placing acoustical panels on your known reflection points will not only effectively clean up the sound in the room. However, the right amount will eliminate all echo and noise issues.
Room acoustics correction
Correcting the acoustics of a room has the main benefit of improving the well-being and acoustic comfort of its occupants. Acoustic panels are used when the echo or sound resonance of a room is too strong. This can be due to the materials used in the construction of the building (glass, concrete or metal) or simply because the decoration is too minimalist. Echoing sound can often give the impression that there is unpleasant background noise due to the increase in the volume of the sound. Rooms with an excessively high resonance result in a permanent loss of intelligibility. This leads to tiredness and lack of concentration for their occupants. Regardless of the space concerned, if you carry it our correctly, the acoustic treatment is effective immediately (following a correct assessment).
Materials for acoustic boards
The materials used in making acoustic boards differ, and it can influence significantly on the quality of the sound absorption. Some interesting fact about this is:
- Cheap materials such as packaging foam will absorb sound much less efficiently than professional grade acoustic wall tiles.
- If the fabric you cover your acoustic panels with is not acoustically transparent, then it will negatively impact the effectivity of your wall and ceiling panels.
- Professional-grade acoustic wall panels and ceiling panels look fantastic. They blend seamlessly with your existing decor or even add to a beautiful interior design style.
- The price of professional acoustic solutions has fallen dramatically due to improving technology. You can now acoustically treat rooms with top-end acoustic panel kits for just a tad more than a DIY project would cost in the first place.
