Abstract
The paper reports the results of an experimental study of the Reverberation Method. The assumptions made in the Reverberation Theory are critically examined. The fundamental equation at1 = 9.2Vv log10 4Eaı̣v affords two independent means of measuring the change produced in the quantity a for a given room, using a source whose acoustic power may be varied in known ratios. Outstanding differences in the experimental results of the two methods, are reported and possible explanations therefor are discussed. Effects of size and shape of test sample, and quality of test tones on measured values of the absorption coefficients are reported. For detailed account of some of the matter reported reference may be made to Journal of the Franklin Institute for March 1929. Later work included experimental verification of a linear relation between the amplitude of vibration of the electrically driven piston source and the magnitude of the driving current.
