Acoustic Panels and Preventing Noise

Noise can be annoying, make it whisper®

We compared dozens of the leading brands in acoustic panels 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 panels.

The majority of acoustic panels or noise barriers are made from open cell foams, fabrics or a mass-loaded vinyl.

Most acoustic panels or sound barriers are not UV resistant, Fire retardant or suited for outdoors. Open-cell foams will attract moisture and are not washable.

Why Is Whisper Foam The Best Solution For Your Next Project?

Whisper converted to a wave shape for cinema walls

Design - PJ Bowers offer foam design and machining capabilities in-house, making architectural designs a breeze.

Whisper foam panels used on ceiling and walls of recording studio

Test data - Sound testing data proves that Whisper compares to serious top of the line studio sound proofing foam solutions.

It’s waterproof and moisture resistant - Whisper foam is closed cell, no water, air or moisture can enter, other foams can be like a sponge to water, even moisture in the air.

It’s UV resistant, suitable for outdoors for more than 50 years - in testing panels were exposed to UV, heat, water, and road salt. Even when aged encrusted with salts, Whisper® maintained similar acoustic panels to as if the material were new.

What is Electrolysis and galvanic corrosion?

Galvanic Corrosion is the corrosion that occurs when two dissimilar metals are used together in a structure and exposed to an electrolyte (salt water, chemical, petrol) and the less noble of the 2 metals will corrode. For example; aluminum sheet with steel fasteners on a boat. Some pairings of metals are more at risk of . Check a galvanic series or chart.

Electrolysis is the acceleration of the galvanic corrosion when electricity is introduced to the metals in question. Connected by an , the less metal experiences accelerated galvanic corrosion.

while both processes involve metals and electrolytes, their dependence on an external voltage source distinguishes them.
