摘要: Factories today are equipped with diverse mechanical equipment in response to rapid technological and industrial developments. Industrial areas located near residential neighborhoods cause massive environmental problems. In particular, noise pollution results physical psychological discomfort, is a seen as invisible inevitable problem. Thus, reduction critical urgent matter. this study, rigid polyurethane (PU) foam plates undergo perforation using tapping machine. The acoustic properties of these perforated related rate depth evaluated terms compression strength, drop-weight impact sound absorption coefficient. Experimental indicate that applying the process endows PU foaming greater load better at medium high frequencies.
