Sound reduction index

The Sound Reduction Index (Rw) is a measure used to quantify the sound insulation performance of building elements such as walls, floors, and doors. It indicates how effective a particular building component is at reducing the transmission of sound from one side to the other. The index is expressed in decibels (dB). Key aspects of the Sound Reduction Index include: 1. **Measurement**: The Rw is determined through standardized testing procedures, usually conducted in an acoustic laboratory.
