3D Acoustic Design: 2inch foam helps break up sound waves to provide a perfect level of moderate sound control on walls or ceilings, effectively absorbing unwanted flutter echoes
The baffle is made of environmentally friendly material, which not only has effective sound-absorbing properties, but also does not cause any harm to our body.
The foam board is compressed in a vacuum pack and air-dried by placing in a well ventilated area for about 24-48 hours or soaking the foam in water for a minute, then wringing out the water and using a hair dryer or letting it quickly return to normal size to air dry/sun dry.
Easy to use, perfect for processing live sound on the walls of your studio or office - perfect for recording studios, control rooms, office home studios, home entertainment theaters, home offices. Easy to form and cut to size, changes will not affect performance.
Acoustic foam is flame-retardant, stops fire from spreading and reduces strength for durability
