The two most commonly-used sound absorption materials are high-quality acoustic foam, Studiofoam® and specialized acoustic fiberglass, ProPanels™ (no, not the stuff you buy at the hardware store). For brevity, at times we'll generically call acoustic foam just plain "foam," although there are very dramatic differences in cell structure and density between acoustic foam and the thousands of other types we could manufacture. (This is why you can't just run down to the local SuperMart and buy mattress pads with which to acoustically treat your studio.)
In addition to Studiofoam and ProPanels, Auralex offers a variety of absorptive products, some of which are fire-rated. Our SoniCell™ acoustic panels are a fantastic solution for budget conscious projects that do not demand designer treatments such as our fabric-covered ProPanels.
Auralex Studiofoam is well-suited to alleviate slap and flutter echo, the two most common problems in rooms not specifically designed for music recording and performance. In fact, Studiofoam can turn even the most cavernous warehouse or gymnasium into a suitable acoustic environment.
