The paper describes a specific design of the sound insulating enclosure of the vibrating sorter. Recycling aspects have also been taken into account when designing the enclosure, because recycled foam has been applied as a sound-absorbing material. Acoustic camera was used to measure, analyze, evaluate and for sound sources localization and identification. The visualization method was used to locate the critical locations of the device and then quantify them. To evaluate the effectiveness of the proposed enclosure, the measurements of the sound parameters were performed before and after the realization soundproofing measure. The measured results show the requested efficiency of the sound insulating enclosure in terms of noise reduction as well as dust in the vicinity of the sorter.
