Sound Transmission

• Sound Transmission Class (STC) Rating - The Sound Transmission Class (STC) rating assesses the ability of materials or assemblies to reduce the transmission of airborne sound. This formula helps in the assessment and measurement of sound insulation performance.
• Sound Transmission Loss (TL) - The sound transmission loss (TL) is a measure of the reduction of sound energy passing through a barrier. This calculator helps find the sound transmission loss in decibels.
