SOUND TRANSMISSION CLASS RATINGS FOR CONCRETE

DETERMINING SOUND TRANSMISSION CLASS (STC) FOR CONCRETE MASONRY. Sound transmission class (STC) provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications.The STC of a wall is determined by comparing sound transmission loss (STL) values at various frequencies to a standard contour.STL is the decrease or attenuation in sound
