Inhomogeneous absorption and geometric acoustics
The Journal of the Acoustical Society of America, 1998 The conventional formulation of geometric acoustics in the presence of inhomogeneous (spatially varying) absorption is examined. This formulation is found to fail under conditions of multipath propagation, because interference between ray paths is not taken into account when the absorptive losses are calculated.

On acoustic absorption in tissue.
The Journal of the Acoustical Society of America, 2011This work extends the relaxation theory of sound absorption to the case of continuous distribution of relaxation times. Such an extension is needed when the absorption mechanisms are not confined to viscosity and heat conduction, but are due mainly to the excitation of a large number of internal molecular degrees of freedom.

Mechanism of Acoustic Absorption in Tissue [PDF]
The Journal of the Acoustical Society of America, 1952 A viscous mechanism for the absorption of ultrasonic energy in tissue is considered. It is shown that the viscous forces acting between a suitably chosen distribution of suspended particles or structure elements and a suspending liquid can account for the experimentally observed linear relations between acoustic absorption coefficient and ultrasonic ...

Acoustical Absorption of Porous Pavement
Transportation Research Record: Journal of the Transportation Research Board, 2008Acoustical absorption coefficients of more than 140 pavement cores were obtained by the impedance tube method with two microphones and cross-spectral analyses. The effectiveness of the impedance tube in predicting noise reduction for different mixes was evaluated by comparing the correlations between onboard sound intensity levels and absorption ...

Scattering and Absorption by an Acoustic Strip
The Journal of the Acoustical Society of America, 1951A method for treating the scattering and absorption of sound in the presence of non-uniform boundary conditions is applied to the case of an infinite strip of material (of given width) placed on an infinite, otherwise hard, wall. The strip is assumed to be characterized by a normal acoustic impedance that may possess a resistive component.
