Theoretical Study of Straight and Ragged Edge Noise Barriers
Monday, April 13, 1998 4:00 p.m. Penelope Menounou Department of Mechanical Engineering The University of Texas at Austin http://www.me.utexas.edu Experimental investigations have shown that noise barrier performance can be improved by making the top edge randomly ragged. A new method termed Directive Line Source Model is presented for predicting the sound field (pressure time waveform)…
