Generally sound absorption coefficient is adopted as the index for evaluating the sound absorbing performances of a material. It is the ratio of the sound energy absorbed by a material (E) to the overall sound energy previously spread and reaching the surface of the material (E0), also called sound absorption coefficient (α).

Light absorption occurs when atoms or molecules take up the linear absorption coefficient the fraction of a beam of radiation absorbed per unit thickness of absorber.

In a material with a low absorption coefficient, light is only poorly absorbed, and if the material is thin enough, it will appear transparent to that wavelength. The absorption coefficient, or rate at which incident radiation decreases with depth, is about 0.1 cm -1 for snow and only 0.001 cm -1 or less for clear ice. Ice is weakly birefringent, or doubly refracting, which means that light is transmitted at different speeds in different crystallographic… ABSORPTION COEFFICIENTS www.akustik.ua FREQUENCY Hz MATERIAL THICKNESS 125 250 500 1000 2000 4000 MASONRY WALLS Rough concrete 0,02 0,03 0,03 0,03 0,04 0,07 Smooth unpainted concrete 0,01 0,01 0,02 0,02 0,02 0,05 Absorption coefficients of common building materials and finishes Floor materials 125 Hz 250 Hz 500 Hz 1 kHz 2 kHz 4 kHz Carpet 0.01 0.02 0.06 0.15 0.25 0.45 Molar absorption coefficient (ε) Synonyms: Molar extinction coefficient, Molar absorptivity "The recommended term for the absorbance for a molar concentration of a substance with a path length of l cm determined at a specific wavelength. Its value is obtained from the equation ε = A / cl The absorption coefficient is therefore described as the reciprocal of the depth of penetration of radiation into a bulk solid, i.e., it is equal to the depth at which the energy of the radiation has decreased by the factor of e-αx, or alternatively, the intensity of the incident radiation is attenuated by the solid to 1/e of its initial value at a distance from the surface boundary defined by λ /4πk.
