Perfect for everything from amateur home podcasting to video game livestreaming to professional studio recording, our Harbour Housewares Foam Acoustic Panels will help you to achieve perfectly crisp, echo-free sound in every take. Each panel in this pack features a distinctive triangular wedge design, crafted from open-celled foam. These cells absorb sound waves that, through friction, are converted to heat, reducing dramatically the amount of energy available for that sound to be reflected back into the room. The result is an audio recording with far greater clarity and crispness than one created without any acoustic treatment, featuring less unwanted echo, reverb or other background noise. Our panels come vacuum packed, yet expand to their full thickness in as little as 30 minutes! A series of adhesive stickers lets you easily affix your panels to any suitable wall or surface, in whatever formation you desire; the perfect custom acoustic wall treatment for rooms and studios of all shapes and sizes! PLEASE NOTE: If creased or flattened upon arrival, we recommend to soak the item in warm water. These will subsequently return to it's full intended size.
