Exposure to the noise in the frequency range 10 ÷ 40 kHz at workstations of welding machines – technical way of limitation exposure
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2016, Vol 32, Issue 2
Abstract
This article shows results of exposure to noise in the frequency range 10 ÷ 40 kHz at chosen workstations with ultrasonic welding machines. This paper presents limitation examples of ultrasonic noise emission through the use of technical ways in the cases of two workstations. Ultrasonic noise emission at workstations was reduced with casing of one welding machine and sealing case of the other welding machine. Exposure of workers to ultrasonic noise at welding workstations decreased at the same time.
