Measureing Noise of Scroll Compressor Based on Structure Acoustic Radiation

Based on the principle structure acoustic radiation of vibration surface,a specific method that detect the noise of equipment through measuring the vibration signals is put forward,according to the correlation between vibration and noise.And a vibration—noise empirical formula of scroll compressor is obtained by the way of experiment.Then,a speedy and accurate noise detection programme of scroll compressor is carried out,after simplifying measuring points,and it can be applied in the production field.
