The buildup of an acoustic door combines layers of sound-absorbing materials like mineral wool, strong seals, and sturdy door frames. These elements function together to limit noise, typically achieving sound transmission class (STC) ratings of 35 or more. Such level of sound insulation is important to block out external noise or to trap internal sounds to certain areas.
