Acoustic panels prevent sound from reflecting off hard surfaces, like ceilings, floors and walls by absorbing the waves. The result is a smooth, quiet and calm environment.
This is very useful for reducing reverb. You can mount them with poster strips.
This listing is for a pack of 12 panels. Each panel is 12″ x 12″ with 1″ width.
