The sound absorption coefficient indicates how much of the sound is absorbed in the actual material.The absorption coefficient can be expressed as:α = Ia / Ii ………………….. (1)whereIa = sound intensity absorbed (W/m2)Ii = incident sound intensity (W/m2)absorption coefficient of materials varies from 0 to 1

An example of light absorption is a crystal. Crystals absorb light and then reflect the light back out resulting in the appearance of a rainbow.
Location of the Stereo, placement of the speakers, location of furniture in relation to the stereo speakers, and sound absorption materials in the room all affect the quality of sound from a stereo.
RADIO
Yes - the amount of absorption can depend on the frequency.

Save, Safety and sound
The rate of sound absorption of an object, surface or body is called the "Absorption Coefficient" which relates to the amount of sound absorbed by the surface. see this chart for details http://www.saecollege.de/reference_material/pages/Coefficient%20Chart.htm
