Acoustical Society of America Noise Standards
The Acoustical Society of America (ASA)’s noise standards include the S12 series, which is a multi-standard series that primarily focuses on the measurement of sound level in an environment and from different sources. A popular standard listed here is ASA/ANSI S12.2, the Criteria for Evaluating Room Noise, which covers the measurement of room noise using noise criteria curves and a method for evaluating low-frequency fluctuating noise using room noise criterion (RNC) curves.
