On the sound absorption by openings in rooms (L)
The Journal of the Acoustical Society of America, 2012Sound absorption by openings has been rarely considered in room acoustics. In fact, information about small openings (such as ventilation grids) may sometimes be found, but nothing is said about larger openings, possibly as a consequence of the less likely occurrence in a design. In order to fill this gap, measurements were carried out in scale models,

Sound Absorption in Electrolytes
The Journal of the Acoustical Society of America, 1965Further ultrasonic-absorption measurements have been made at 104–108 cps in a number of electrolytes including iodides, chlorides, acetates, acetic acid, and mixtures of electrolytes. A number of these electrolytes exhibit interesting relaxation effects, which have been interpreted quantitatively in terms of specific ion-ion and ion-solvent ...

Two pelts of fiberglass are bonded together to form a sound absorption panel. One pelt is deformed to a sawtooth shape and the teeth of the sawtooth pelts are bonded into grooves in the other pelt which is essentially flat except for the grooves.

The absorption of sound in emulsions
Acoustical Physics, 2010The absorption of sound in homogeneous dilute emulsions due to the viscosity of the components of the medium is theoretically investigated. Deformation (capillary) oscillations of the emulsion droplets are taken into account. The viscous wavelength is assumed to be small compared to the droplet size, and the latter is assumed to be small compared to ...

Experimental measurements of the absorption of sound in still air exhibit a distinct deviation from the theoretical predictions based on known classical and molecular absorption losses. Absorption coefficients have been measured in humid air over the humidity range of 0% to 100% relative humidity.
