US Patent 7503428 Acoustic panel

An apparatus and method is disclosed for an improved acoustic panel comprising a sound absorbing member defined by a first and second face surface and a plurality of peripheral edges. A sound blocking member is defined by a first and second face surface and a plurality of peripheral edge. The first face surface of the sound blocking member is secured relative to the second face surface of the sound absorbing member for blocking the transmission of sound therethrough. In another embodiment, the first face surface of the sound blocking member is spaced relative to the second face surface of the sound absorbing member for decoupling the sound blocking member from the sound absorbing member.
