ISO 532-1:2017 is an international standard published by the International Organization for Standardization (ISO) that outlines methods for calculating the perceived loudness of sounds. It specifically focuses on the Zwicker method, a technique for estimating loudness based on sound pressure levels and frequency bands. The standard provides guidance on how to measure and interpret these sound levels, ultimately aiming to quantify how loud a sound will be perceived by a person.
