Interest of predictive simulation for noise level assessment at the work place.

摘要

Sound level in an industrial room depends on a large number of parameters : the sources of noise, the room geometry, the wall absorption properties, the fittings etc. It is interesting to be able to predict sound levels in a given industrial room in order to adapt the acoustic treatment in conjunction with a better fitting distribution. A numerical simulation software "RAYSCAD+" designed by National Institute for Research and Safety in occupational health has been developed in order to give a computer-based tool to people in charge of prevention of occupational risks. This paper is intended to present some results of numerical simulations from actual situations in different activities.
