The Application of the Norris-Andree Method of Reverberation Measurement to Measurements of Sound Absorption
View through CrossRef
Several methods of measuring sound absorption are in use but require rather large samples. The Norris-Andree method of reverberation measurement theoretically lends itself to sound absorption measurement, permitting relatively small samples to be used and necessitating no reference absorption material.
The paper outlines in detail the mechanical application of this method to sound absorption measurement and presents data collected over a year's time in making such measurements.
