The purpose of an acoustic panel is to tame the unwanted acoustic characteristics of a recording or critical listening space. The operating principle is straightforward: The panel is made from a good quality sound absorbing material wrapped in a acoustically transparent fabric. When these panels are mounted panel on the walls or ceilings of a space sound striking the panels is absorbed rather than reflected. Reducing the amount of reflected sound generally improves the quality of the listening or recording experience in a space.
We make two standard size panels: a wall or ceiling mount absorber (1244mm x 644mm x 60mm) ideal for listening spaces and a large mobile absorber mounted on castors (1800 x 1000 x 100mm) which is ideal for recording spaces. We used these extensively in the studios at SAE Institute Cape Town and there are several photos on the project page here.
