Stc sound rating.

The STC rating is concerned with the travel of sound or noise (sound above a certain threshold for which it is considered unwanted) through the air. The STC measures how well an assembly of materials absorbs the transmission of airborne sound/noise. Assemblies not only include interior partition walls, ceilings/floors, and exterior walls, but ...A single-number rating system used to express the . sound transmission loss properties of a wall or roof is the sound transmission class (STC). The higher the STC value, the better a construction reduces the transmission of sound. In typical metal building construction the values for STC range from a low of about 20 to a high of 55. The STC ...It’s the measurement of how much noise is reduced as it passes through a medium. The majority of common STC ratings fall within a range of 20 to 60. An STC rating of 20 is considered very poor soundproofing quality whereas an STC rating of 60 is considered excellent soundproofing quality.

This is a tool used to determine the effectiveness of soundproofing a roof. It’s an integer rating that tells us to what degree a building partition (such as a wall or ceiling) reduces the force of airborne sound. In sum, STC tells you how much a ceiling or wall might stop sound. STC Precepts “An STC rating roughly equals the decibel (dB) reduction in noise volume a wall or partition can provide. For example, if an 80 dB sound on one side of a wall/floor/ceiling is reduced to 50 dB on the other side, that partition is said to have an STC of 30” Source : Minnesota Sustainable Housing Initiative
