GB/T 42553-2023 "Electroacoustics - Methods for determining the free-field response corrections of sound level meters" specifies a unified method for determining the response corrections of sound level meters under free-field conditions. It aims to provide a technical basis for sound level meter manufacturers and testing laboratories to compensate for the effects of sound level meter housing reflections, microphone acoustic diffraction, and accessories such as windshields on measurements. This ensures that the measurement of correction values at calibration check frequencies is accurate and reliable.
