Abstract

This paper is focused on the measurement systems for obtaining the characteristics of the screens used in controlling industrial noise and urban traffic noise. There are two systems that could be used for a good determination of the acoustical parameters of the screens. The method and the system have tested "in situ" by the specialists of The Research Institute for Construction Equipment and Technology ICECON S.A. Bucharest and those from The Research Centre of Machines, Mechanic and Technological Equipment - MECMET.
