GB/T 3785.1-2023 "Electroacoustics - Sound level meters - Part 1: Specifications" is the core specification for the performance of sound level meters. It defines the electroacoustic performance requirements for three types of instruments: time-weighted, integrating-averaging, and integrating sound level meters. According to accuracy and temperature range, sound level meters are classified into Class 1 and Class 2. The standard specifies the frequency response under free-field conditions and applies to all types of sound level meters, ranging from handheld devices to multi-component systems.
