Material, structure or object which absorbs sound energy during collision with sound waves.
Describes material's ability to absorb sound and is measured over a number of specific frequencies. Result is expressed as a number between 0 (total reflection) and 1 (total absorption). When multiplied by 100, number represents percentage of absorbed sound.
A device which increases mechanical vibrations.
Point from which spherical waves seem to be diverging when the transducer is acting as a source.
Phenomenon reciprocal of acoustic stiffness. Also called acoustic capacita.
Interaction between the room, the loudspeaker, and the listener.
A device which passes only the sound in specific range of frequency, while rejects sound in some other range.
A series of rods of equal size arranged in a row with fixed distance which causes sounds with different wavelengths to be diffracted in different directions.
A ratio of sound-pressure amplitude to volume-velocity amplitude through the surface in the acoustic medium.
