Abstract

As an essential equipment, the fan is widely used in industrial and civil fields for gas compression and gas delivery. Though the cooling fan can keep us comfortable temperature, it bring the annoying noise. Usually noise reduction will first be conducted to the cooling fan, however, the sound quality of cooling fan is also an important factor to annoy the people. In the paper, sound quality evaluation model for cooling fans will be established to evaluate the sound. It helps screen the objective parameters, including loudness, sharpness, etc. Also, it serves as the output when training the Back Propagation (BP) Neural Networks. Thus, it is important to find an appropriate method to complete the subjective evaluation experiment. In this test, various subjective evaluation methods are compared. And the best method for cooling fan sound quality evaluation is selected by analyzing the correlation coefficient between subjective and objective evaluation result.
