摘要
本文在应用声级计、传声器和倍频程滤波器对小型离心风机噪声测试的基础上,用信号处理进行频谱分析,精确地找出小型离心风机产生嗓声的机理和特性,可为设计低噪声的小型离心风机和噪声控制提供较为可靠的数据。
The paper carried out the frequency spectrum analysis by using signal processing
on the basis of the measuring the noise from small centrifugal fan by means of sound level meter,
microphone and the octave filter. It exactly found out the mechanism and characteristics of the
noise which the small centrifugal fan produced, providing precise and reliable data for designing
lower noise small centrifugal fan and taking the measure for the noise control.
