Effects of acoustical ceiling panel type: Vertical sound isolation

Construction Specifier

One of these is to achieve greater vertical noise isolation—the acoustic ceiling panels suspended below the concrete slab should: be made of a certain material, such as wet-felted mineral fiber; have a certain minimum weight, for example, 5 kg/m 2 (1 psf); and. earn a minimum ceiling attenuation class (CAC) rating of 35.
