ATTENUATION OF SOUND AS A FUNCTION OF BARRIER ANGLE
Oblique wall noise barriers were investigated for angular dependence of attenuation. Experiments with a model at 5 kHz showed less than 1 dB difference from normal incidence to 45 degree incidence. Variations may approach 2 dB at angles near 70 degrees from normal incidence. Thus, the obliquencess of the wall may be neglected for most practical problems.
