✦ Synopsis


This paper presents experimental data on the diffraction of sound round a semi-infinite plane screen in a free field and describes a method for calculating the shielding effect of a real screen employed for the purpose of noise reduction, with the assistance of a single graph and without the aid of a computer.

This paper presents a method of estimating the excess attenuation of noise by a thick barrier. In this method, the excess attenuation of noise by a thick barrier is assumed to be composed of two parts, one being the effect of a virtual thin barrier with the same height and the other the effect of th
