What is an STC Rating?
What is an STC Rating?
An STC rating is a single number that indicates how well a structure or material blocks noise from transmitting through it. How STC ratings are calculated is a bit more complicated than a single number, but by simplifying to one value - we can easily compare products and assemblies relative to the soundproofing requirements for a space.
