This sound absorbent material is often used to reduce noise pollution. Acoustic foam can be seen lining rooms or spaces such as a recording studio, broadcast studios, and even laundry rooms. Acoustic foam is just one example of soundproofing material.
Noise pollution is when any form of noise is undesirable, thus making the need for soundproofing materials. This specific foam is penetrated by sound energy and then dissipates the sound. It is typically made of urethane open-cell foam which is a soft and weak material. Gyms, bars, restaurants, halls, churches, and even airplanes implement acoustic foam into their structures.
Similar to all sound proofing materials, the greater the surface area of the foam, the greater the sound absorption can be implemented. This means acoustic foam is often designed in a pyramid or egg shape to create an uneven surface. Often times there is a film or solution that is covering it when its application could be exposed to high temperatures or moist conditions. This soundproofing method is traditionally inexpensive.
