Sound Transmission Class (STC) Testing:
Sound transmission class (STC) is a rating of sound isolation of a building wall assembly. The higher the STC rating, the better sound isolation the wall assembly is to achieve. STC is widely used to rate interior partitions, ceilings/floors, doors, and windowsas per ASTM E90 / 413 / IS:9901-III/ ISO: 140.

Noise Reduction Coefficient (NRC) Testing:
The noise reduction coefficient (NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material.An acoustic product absorbs sound and the NRC tells us just how much sound those products can soak up. NRC is measured on a scale that ranges from 0 to 1. An NRC of 0 means that the product absorbs no soundas per IS:8225 / ISO: 354 / ASTM 423C.
