Does Cellulose Insulation Insulate Against Sound…?
The best way to determine effectiveness of cellulose insulation as a sound control material is to conduct reliable, scientific tests. Sound Transmission Class (STC) is a laboratory measurement used to study the resistance of a wall, ceiling, or floor to the passage of sound. The higher the STC number, the more sound is deadened. The table below gives examples of STC ratings of cellulose insulation compared to fiberglass and no insulation.
