Acoustic foam is an insulation material that will help eliminate echoes and diminish sound frequencies. Sounds vibrate most off flat walls with no texture and off solid floors and ceilings. If a floor or room has ceramic, it will echo louder and the sound will carry heavier and further.
Acoustic Foam is used to maximize on “flattening” the sound in your room so when you record or play back music, the sounds do not echo throughout the room.
Sound frequencies are of high and low nature. Low frequencies are most deadly in squared corners so corner solutions aka bass traps are what you’ll need to stop those low frequencies from vibrating all over the place.
Why Acoustic Foam
Once the sound waves penetrate the foam, they will get caught into those small cells. Afterwards, the sound waves will spin and bounce until they can make their way out. And, during all the spinning and bouncing, they will most likely lose a significant amount of energy, which leads to them dying more quickly than usual.
Acoustic foams are usually cut in small panels with wedge or pyramid patterns. However, there are larger sheets and other patterns, too. Furthermore, having in mind that the materials used for acoustic panels have a chemical composition, you might notice a chemical odor. But, keep in mind that this odor is not harmful and will dissipate almost immediately. Hence, you can relax and focus on the benefits and the usefulness of this product.
