The walls, floor and ceiling of the anechoic chamber are lined with flat-tipped fibreglass wedges designed for a cut-off frequency of 50 Hz. The interior (wedge tip to wedge tip) is 13 m long, 9 m wide and 8 m high. In order to create well-defined noise exposures and measurements of sound power and sound pressure in the chamber, its free-field performance must be quantified. This provides baseline estimates for errors in sound pressure measurements and a technique for error estimation as measurement configurations change. This paper describes characterization of the free field performance from 50 to 5000 Hz along the chamber axis. Implications for measurement uncertainties in the anechoic chamber are discussed}, number={3}, journal={Canadian Acoustics}, author={Keith, S.E. and Davidson, M.G. and Bly, S.H.P.}, year={1994}, month={Sep.}, pages={33–34} }
