Noise source visualization of conveyor systems on the postal packaging sorting line
Abstract
Sound visualization tools are now used for the identification and localization of noise sources. This paper aimed to locate and quantify noise sources on a packet sorting line using an acoustic camera and then propose noise reduction measures. Localization of noise sources was performed using an acoustic camera with a microphone ring array. The result of these measurements and analyses was to sort the individual noise sources from less noisy to the noisiest, which gives a good assumption for better planning of spending on the implementation of noise reduction measures. The outputs of these measurements also give information on the character and frequency composition of the sound of individual sources, which will help out in the design of specific measures for noise reduction.
