Specific Normal Impedance and Sound Absorption Coefficients of Materials [PDF]
The Journal of the Acoustical Society of America, 1941 This paper reports the results of comparison measurements of “reverberation coefficients” made on identical samples of materials in three reverberation chambers, having volumes ranging from 10,000 to 15,000 cubic feet. The results of these measurements indicate that, in rooms of comparable size, discrepancies in the measured values of the ...
