The Sound Transmission Class STC is the rating of airborne sound transmission. Acoustic flooring is designed to insulate impact noise preventing its transmission from your flooring into the rooms below. Sound Transmission Class is measured in a laboratory and tests a materials ability to reduce sounds like voices televisions alarm clocks and more.
A flooring materials effectiveness at preventing the transmission of impact noise is measured by its impact insulation class ICC. The sound transmission class STC rating of a floor measures only the reduction in airborne sound transmission. Ad Browse discover thousands of brands.
Sound transmission class STC is a rating of sound isolation of a building wall assembly. This rating can be 12311. Section 1207 of the 2015 IBC states that wall and floorceiling assemblies separating dwelling units must meet a Sound Transmission Class STC rating of 50 or 45 for field tested assemblies tested in accordance with ASTM.
In the US it is widely used to rate interior partitions ceilings floors doors windows and exterior wall configurations. A floor however also transmits structure-borne sound such as footsteps or a slammed door directly through the materials. There are two widely accepted tests for sound that travels.
The STC rating very roughly reflects the decibel reduction of noise that a partition can provide.
