Acoustic Aluminum Metal Perforated Punching Panel Garden Decoration

Aluminum panels are often manufactured into sound barriers for lightweight, excellent corrosive resistance and self-support. Aluminum sound barriers are not only used in traffic areas but also factories and workshops where machines make serious noise pollution.

As an absorptive sound barrier, aluminum panel are designed with various hole patterns such as dotted or slits. The surface is porous, where there are small cavities or holes that extend into the interior of the barrier material, a portion of the sound waves will travel inside the cavities when they reach the surface. The waves will bounce around and eventually expend all their energy. To maximize sound absorptive performance, fillings are required such as EPDM, fiber glass and aluminum foam.
