Research on Noise Distribution Method of Intelligent Toilet Based on Cylindrical Envelope Surface Method
Based on the hemispherical envelope method,this article introduces the layout method and explores the dif-ferences and reasons for the measurement results of intelligent toilets in different usage stages such as blowing,flushing,and cleaning through the cylindrical envelope method. The measurement results are corrected by noise source distance attenuation and compared with the hemispherical envelope to reveal the influence and causes of pressure and gravity flushing devices on noise measurement results.
