Application Summary AI generated
GB/T 3767-2016 specifies engineering methods for measuring the sound power and sound energy levels of noise sources using sound pressure in an essentially free field over a reflecting plane. It is applied in industrial and product testing contexts, such as evaluating the noise emissions of machinery, equipment, or appliances in semi-anechoic rooms or large indoor spaces with a hard floor. This standard is used by manufacturers and testing laboratories to ensure consistent and comparable noise level declarations for compliance with regulations or product specifications.
