✦ Synopsis

This paper gives an indication of the sound isolation that can be achieved in a single-walled free-fieM chamber based on one of the panel systems commonly used to construct noise enclosures in factories. Isolation exceeding 40 dB at frequencies of 200 Hz and above has been measured in a chamber lined with 0"4 m long absorbent wedges and having a free volume of 2"2 x 2.2 x 2.6 m between the wedge tips.

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.
