Understanding Sound Transmission Class (STC) Rating

WebbSome professionals prefer Rw because it corresponds to the decibel scale. So an Rw 50 rating means you could expect the noise you want to ‘block’ to be reduced by 50 decibels. DnTw – onsite / in situ Sound Insulation Rating. The DnTw rating describes the acoustic performance of a completed part of a building. WebbTo solve this, acoustics professionals created several single-number ratings to quickly compare and reference different partitions.
