The aim of the study is to measure, model and reduce the acoustic impact of the conveyor belt system planned for one of the Polish power plants. This system is at the design stage and its elements will constitute additional noise sources.The analysis includes assessment of noise sources and making an acoustic model for the current state of the conveyor system, followed by preparation of an acoustic model for the designed system for transport of biomass and calculation of the level of noise emission in the environment from the Power Plant area. The study also includes proposals for the system optimisation dedicated to minimising the acoustic impact.The analyses carried out confirm that the need to minimise the acoustic impact on the environment of belt conveyors operating in power plants directly is of an individual nature and depends on the location of the layout of these conveyors in relation to the land use of adjacent areas and the permissible noise values for them.When designing new installations, it is necessary to take into account not only the selection of the acoustic parameters of the equipment and mitigation measures, but also the possibility of using the existing infrastructure located in the path of noise transmission in shielding.The methodology used, both measurement and optimization one, using the virtual reality simulations, can be applied as a universal tool for limiting the noise emitted into the environment by conveyor belt systems operating in various conditions.
