What is a soundproofing barrier?

Noise barrier or sound barrier products add mass to a wall, ceiling, floor, or enclosure serving as a highly effective soundproofing solution - at an affordable price. Soundproofing barriers are typically installed on the studs or joists to reduce airborne sound transmission between the source and the target.

What is STC?

Sound Transmission Class (STC) is the weighted average of the transmission loss between the Sound Source and the Target. It is a rating assigned to a material or an assembly of materials to represent the decibel (dB) reduction across the frequencies ranging from 125 Hz to 4000 Hz. The difference between the Sound Source and Target, in decibels, is referred to as the Transmission Loss. Measurements are taken at 125, 250, 500, 1000, 2000, and 4000 Hz to arrive at the overall STC rating.
