ANALYZE OF NOISE BARRIER INFLUENCE ON THE LINEAR SOURCES

Alin Cosmin TOT, Mariana ARGHIR

Abstract


This paper aims to quantify the influence of the theory of noise barriers mounted along linear sources. For this purpose were analyzed four types of barriers with heights of two meters at the same time, comparing the influence of sound-absorbing structures, if mounting the barrier on the surface of these structures in the vicinity of the incident wave front. Thus, the analysis of acoustic condition was achieved at frequencies of 100, 150 and 250 Hz. sound absorbing structures Coefficients are 0.2, for frequency of 100 Hz and 0.5 for the frequencies of 150 and 250Hz.
