Abstract
An historical survey of the techniques of measurement and assessment of anechoic chambers is given with a view to deciding the optimum method of evaluating the new anechoic chamber at Bradford University. Experimental results taken on the chamber, using the inverse distance and frequency response tests, are presented. An attempt is made to correlate the results of these tests with predicted results obtained from steady-state measurements taken, in an interference tube, on the novel type of absorber used in the chamber. In conclusion, guidelines for the design of small anechoic chambers are given.
