Urban traffic noise can be a major issue for people and (local) governments. On a local scale the use of measurements is increasing, especially when measures or changes to the local infrastructure are proposed. However, measuring (only) urban traffic noise is a challenging task. By using a model based monitoring system, consisting of a scalable...

Sound reflectivity is one of the intrinsic acoustical characteristics of noise reducing devices (NRD’s). It describes which percentage of an incident sound field is reflected back towards the opposite side of the road. The reflectivity is determined by the absorption properties of the material of the NRD as well as by the geometrical shape of...

Within the EU FP7 QUIESST project, QUIeting the Environment for a Sustainable Surface Transport, a test method is being developed for the reflectivity of noise barriers. The method needs to account for a complex shape of barriers and the use of various types of absorbing materials. The performance of a barrier is to be measured in the near field...

We present the last results obtained within WP5 "Holistic optimizations" of the QUIESST European Project dedicated to the assessment of Noise Reducing Devices' acoustical performances. A first task was a state of the art of existing methods followed by choices of best solutions for holistic optimizations of complex-shape noise barriers. Results...

This paper deals with the first stages of the development of a new test method for evaluating the reflectivity performance of noise barriers. The reflectivity performance describes the increase in sound level at a receiver due to the presence of the noise barrier. First the current test method for sound reflectivity is simulated with three...
