Design - PJ Bowers offer foam design and machining capabilities in-house, making architectural designs a breeze.
We compared dozens of the leading brands in acoustic and sound proofing solutions and found that:
Just about any foam or sound proofing panel can achieve 100% sound absorption coefficient at high frequencies. Low frequencies and mid-frequencies, lower than 500 Hz are more challenging to sound proof or absorb.
True noise reducing performers will have good results in low frequencies from 100-300Hz. This is the range in which most annoying noises are heard, such as conversations, TVs, music and power tools.
Cushioned furniture and carpets can absorb about half the sound of the average acoustic foam.
The majority of acoustic foams or noise barriers are made from open cell foams, fabrics or a mass-loaded vinyl.
Most acoustic foams or sound barriers are not UV resistant, Fire retardant or suited for outdoors. Open-cell foams will attract moisture and are not washable.
