ANSI S1.4 (Specification for Sound Level Meters)

ANSI S1.4 is a standard developed by the American National Standards Institute that specifies how sound level meters should be designed, tested, and used. It ensures that these devices measure sound accurately and consistently across different situations. This standard includes guidelines on the frequency response, response times, and calibration procedures for sound meters, which are commonly used in various fields like environmental monitoring, workplace safety, and noise control. By adhering to ANSI S1.4, manufacturers and users can rely on the sound level readings to make informed decisions regarding noise management and regulations.
