GB/T 23282-2009 Metal forming machinery—Noise measurement method of sound power levels
Abstract
This standard specifies the method of measuring sound pressure levels on the measurement surface of the sound source of forging machinery to calculate the noise power level of forging machinery. It also provides methods for calculating the sound pressure level and sound power level in acoustic environments, measurement instruments, and their use.
The methods specified in this standard are only applicable to the measurement of "steady state" and "non-steady state" forging machinery noise under specified operating conditions, and are not applicable to the measurement of forging machinery noise that radiates "pulsed" noise under specified operating conditions. It is suitable for indoor and outdoor environments that meet the specified requirements with one reflecting surface.
Note: For the classification of noise (steady state, non-steady state, quasi-steady state, pulsed, etc.), please refer to GB/T 14259.
