Description Technical features and measures Related documentation

M.A.D.4 (short for Membrana Acústica Danosa, or 'Danosa Acoustic Membrane' in English) is a 3 mm thick high density bitumen modified membrane specifically designed to behave as an anti resonant material. It is an efficient substitute for lead sheets. Between porous absorbers materials works like a panel absorbers (most efficient at absorbing low frequencies).
