## Abstract This paper reports on a new method for the determination of the performance qualities of a semiβanechoic chamber used for electromagnetic compatibility measurements. This approach, based on highly efficient and accurate circuital techniques, provides very good results on lowβcost deskto
The usual criterion of 10 % or less pressure reflection for lining materials of anechoic chambers is related to the real and imaginary parts of the specific acoustic impedance ratio, allowing some more direct relationship between the acoustic and physical properties of the lining material.
