Acoustics is a relatively new science to African shores. Yes every product has an Acoustic quality, some absorb, some reflect and some deflect. But absorption is what we want close to the source before it becomes reflected noise.
New materials like compressed PET, have replaced conventionally fibre materials like Rockwood and are sold as rigid sheets of around 9mm.
This material has an NRC of .85 in certain frequencies and is ideal for use in the construction of Acoustic Desk Based Screens, framed or frameless.
