Acoustic insulation design of noise in welding plant through screens

Abstract

Noise is one of the industrial hygiene agents of greatest concern, which explains the large amount of regulations and literature that attempt to reduce it. In most industries in Peru and the world the welding process is indispensable as part of their production process, nevertheless this activity involves several risks for people, not only for those who perform the activity but also those who are adjacent to it, within these risks, exposure to high levels of noise is one of the most difficult to control because the control at the source of noise is almost, one of the great passive controls in noise reduction is the use of screens or acoustic curtains. It is for this reason that the objective of this article is to propose a design of acoustic barriers through screens, responding to the problem of noise generated in welding workshops. The stages in the process of designing acoustic screens for a welding plant are presented in chronological order.
