CONSIDERATIONS ON THE OUTDOOR NOISE BARRIERS DESIGN AND SIMULATION

Iulian LUPEA

Abstract


Abstract: The article is primarily a review of the design principles and the main factors with impact in the effectiveness of noise barriers followed by considerations on the outdoor sound field simulation with sound barriers. The sound absorption spectrum characterization is the specificity of the employed sound barriers in the simulation. A new sound spectrum associated to the new class of sound absorbing structures with double micro-perforated panels is observed and added in SoundPlan simulation library.

Keywords: noise barrier, insertion loss, transmission loss, sound absorption spectrum, barrier simulation, double micro-perforated panels.
