GB/T 6881.2-2017 specifies an engineering-grade comparison method for measuring the sound power and sound energy levels of small, movable noise sources using sound pressure in a hard-walled reverberant test room. It is applied in acoustical testing environments, such as laboratories or quality control facilities, to evaluate the noise emissions of products like household appliances, office equipment, or small machinery. This standard is particularly relevant for manufacturers and testing bodies needing reliable, repeatable noise data for compliance with noise regulations or product labeling.
