GB/T 16731-2023 specifies a classification system for the sound absorption performance of building acoustic products (such as acoustic panels, sound absorbers). Based on the noise reduction coefficient (NRC) or sound absorption coefficient measured by the reverberation room method, it classifies materials into different sound absorption grades, providing a unified standard for acoustic design and product selection.
