100mm thick perforated rock wool acoustic panel

Perforated rock wool acoustic panels are increasingly used in overall factory noise reduction and industrial equipment sound insulation projects. Due to their excellent performance and lower cost compared to other acoustic panels, they are widely adopted by engineering units.

In laboratory research on perforated rock wool acoustic panels, the standing wave tube and reverberation chamber test methods are commonly used, while the reverberation chamber method is more frequently applied in practical engineering. Experimental tests on perforated rock wool acoustic panels show that when single-color steel perforated panels are used as protective surfaces for porous sound-absorbing core materials, the sound absorption performance is primarily determined by the perforation rate. However, when the perforation rate exceeds 20%, this influence becomes negligible.

Rock wool sound insulation sandwich panels and perforated color steel sound insulation sandwich panels are applied in various fireproof and soundproof environments, such as office partitions, shopping malls, game halls, cinemas, karaoke bars, dance halls, airports, etc.
