Abstract�� In order to get comfortable and natural wind, a method which make power spectrum of wind-s velocity conforms to 1/f�� fluctuation is mentioned. Data conforming to 1/f�� fluctuation by using 1/f�� fluctuation filter controlled the velocity of motor using a booster. By the comparison among feelings got by wind of the 1/f�� fluctuation, that of the 1/f2 fluctuation and that of the white noise fluctuation using variance analysis, a conclusion is drawn that humans- feeling of comfort is implemented efficiently by 1/f�� fluctuation controlled electric fan.
Keywords�� power spectral density   comfortableness   variance analysis   1/��f�� fluctuation   dimensional analysis
