Effect of Painting on the Sound Absorption of Acoustic Materials [PDF]
The Journal of the Acoustical Society of America, 1940 A brief discussion is given of the properties of a material which cause it to absorb sound. Photographs are shown and the results of sound absorption measurements before and after painting are given for a number of different types of material. A brief discussion is given of the kind of paint which can be used and how it should be applied.

Acoustic Absorption of Haired and Hairless Mice [PDF]
The Journal of the Acoustical Society of America, 1955 The measurements reported here were carried out to check those calculated from the heating of mice in the field of the Penn State siren [Danner, Ackerman, and Frings, J. Acoust. Soc. Am. 26, 731–39 (1954)]. In the present experiments the mice were placed in individual containers in a white noise field within a cylindrical reverberant chamber ...
