CALCULATIONS OF IMPULSE NOISE IN THE DESIGN OF MEANS OF REDUCTION IN INDUSTRIAL BUILDINGS

Abstract

At modern industrial enterprises, equipment emitting impulse noise is widespread. Impulse noise has a more adverse effect on the body of working people. Therefore, more stringent requirements are imposed on its limitation. Performing them requires the use of constructive measures to limit the power of radiation of pulses of sound energy by equipment and building-acoustic measures to reduce noise in the ways of its propagation. In both cases, it is necessary to evaluate the acoustic efficiency of the proposed measures. This is possible if there is a calculation method that objectively evaluates the propagation of impulse noise in rooms taking into account their space-planning and acoustic characteristics. The article proposes a statistical energy method for calculating impulse noise, allowing to evaluate its spatial-temporal characteristics when solving a wide range of tasks to reduce the impact of noise on the body of workers. The possibilities of the method are shown in solving these problems.
