Noise Rating [NR] Noise Rating curves have been the international standard for indicating acceptable sound levels within a space. NR curves were developed by the International Organization for Standardization (ISO.) Each curve depicts the acceptable dB levels across a range of frequencies between 31.5 Hz and 8,000 Hz (8 kHz).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.

STC is a rating number of a partition’s (building material or assembly) resistance to airborne sound transmission. Since the STC rating is taken at a standardized 500 Hz frequency, all 16 tested frequencies should be evaluated to fully understand the partition’s performance. The Sound Transmission Class is always reported as a whole number. STC is measured under laboratory conditions for a fully assembled partition. That means you won’t usually find STC ratings for individual components or products since STC is meant to be measured for fully constructed assemblies. The lowest STC numbers you see are around 33. May 13, 2022 · Sound Transmission Class (STC) A Guide to True NRC™ Acoustic Rating. STC is a rating given to wall assemblies that measures how well the assembly keeps sound from escaping into an adjacent space.
