The method promotes accuracy and speed by averaging rapidly what is claimed to be the equivalent of an infinite number of observations. The result is obtained with simple apparatus. Its application to the measurement of airborne sound transmission and loss of noise reduction is given as an example.

A numerical method is presented for calculating the sound pressure around a noise barrier of constant but arbitrary cross-section. To obtain the exact solution of this problem, the Helmholtz equation must be solved in the three-dimensional domain outside the barrier. It is shown in this article how
