Fan, either centrifugal or axial, has been widely used in factory, air-condition system for air handling. However, the noise produced by fan is the main concern by the producer and the user. The main object of this research is to set up a measurement system according to the AMCA 330-86 in order to measure the sound power of an existing axial fan. Besides, the sound quality of the investigated fan was also studied. The measured result shows that the sound power of the investigated fan is extremely high, more than 97dB in design point. The main reason for this high level of noise is due to the improper design of blade by which a high level of broadband turbulent noise is induced.
