风扇噪声的测量

关于风扇噪声的测量，哪位有研究？
ISO有一系列关于风扇噪声测量的标准，不知为什么没有对应的国标呢？

ISO 13347-2       Industrial fans - Determination of fan sound power levels under standardized laboratory conditions - Part 2: Reverberant room method
ISO 13347-3       Industrial fans - Determination of fan sound power levels under standardized laboratory conditions - Part 3: Enveloping surface methods
ISO 13347-4       Industrial fans - Determination of fan sound power levels under standardized laboratory conditions - Part 4: Sound intensity method
ISO 5136             Acoustics - Determination of sound power radiated into a duct by fans and other air-moving devices - In-duct method
ISO 10302         Acoustics - Method for the measurement of airborne noise emitted by small air-moving devices
ISO 5135             Acoustics - Determination of sound power levels of noise from air-terminal devices, air-terminal units, dampers and valves by measurement in a reverberation room
