Influence of Density on Sound Absorption Coefficient of Fibre Board
, 2017 For acoustic applications such as theaters, cinema halls, auditoriums the data on acoustic properties i.e. sound absorption coefficient and sound transmission loss are required to evaluate the acoustic behavior of panel products and to facilitate the ...

ABSORPTION COEFFICIENTS OF AIR [PDF]
, 1960 Abstract : Tables of integrated absorption coefficients were evaluated for high-temperature air by summation of the contributions from discrete and continuous transitions. The tables were computed for dry air in the temperature range from 1,000 deg K to 12,000 deg K, at equal energy increments of 0.25 ev (2,016.5 cm. to the -1 power), in the wavelength

On the effect of superfluid flows on the interaction of microwaves with He II [PDF]
, 2012 The paper proposes a possible mechanism of interaction of microwaves with superfluid helium that results in an experimentally observed narrow peak of microwave absorption on the frequencies by the order of the roton frequency.

On Iterative Algorithms for Quantitative Photoacoustic Tomography in the Radiative Transport Regime
, 2017 In this paper, we describe the numerical reconstruction method for quantitative photoacoustic tomography (QPAT) based on the radiative transfer equation (RTE), which models light propagation more accurately than diffusion approximation (DA).

Spin-hybrid-phonon resonance in anisotropic quantum dots
, 2008 We have studied the absorption of electromagnetic radiation of an anisotropic quantum dot taking into account the spin-flip processes that is associated with the interaction of the electrons with optical phonons.

Predicting theater chair absorption from reverberation chamber measurements - comment [PDF]
, 1993 The relationship between the measured acoustic absorption coefficient of an array of theater chairs and the ratio of the perimeter length to plan area of the array is considered.

, 2017 Remote sensing of chlorophyll-a concentration, [Chl-a], has been difficult in coastal waters like the Chesapeake Bay owing largely to terrestrial substances (such as minerals and humus) that are optically significant but do not covary with phytoplankton.
