Sound Transmission Class (STC) Rating Explained
Sound Transmission Class or STC is the rating system by which the ability of a partition to attenuate, (reduce the effect of) airborne sound is measured.
Learn what STC rating ( Sound Transmission Class ) means for walls, windows, doors, and floors. Discover how to read STC charts, meet building code requirements, boost soundproofing, and choose the best materials for acoustic privacy in your home or office.
Sound Transmission Class ( STC ) is an integer rating of how well a building partition attenuates airborne sound . In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations.
Sound transmission class ratings generally come up in places where we want to keep sound either in or out, like a sound studio, a road-facing exterior wall, or a bedroom above the garage. When people are evaluating building materials and acoustical products for sound reduction, they rely on the sound transmission class or STC rating of the product.

What Is an STC Rating ? Definition: STC ( Sound Transmission Class ) measures how well a partition blocks airborne sound between adjacent spaces. Scale: The higher the STC , the better the sound isolation performance. Purpose: Used to compare wall, door, and window assemblies in architectural and acoustic design. STC ratings help architects and engineers evaluate how effectively walls and ...
The Definition: What STC Actually Measures Sound Transmission Class ( STC ) is a single-number rating that describes how much a building assembly reduces airborne sound transmission across a standardised frequency range. A higher number means more reduction — more blocking — and less sound transmitted from one side to the other.
