ANSI S1.4 (Specifications for Sound Level Meters)

ANSI S1.4 is a standard that provides guidelines for sound level meters, which are devices used to measure sound intensity. This specification outlines the performance requirements, testing methods, and calibration procedures for these meters, ensuring they produce accurate and reliable readings. It covers factors like frequency weighting and time response, which help in assessing different types of sounds, such as constant noise or sudden spikes. By adhering to ANSI S1.4, manufacturers and users can ensure consistency and accuracy in measuring sound in various environments, from industrial settings to environmental monitoring.
