Psychoacoustics is the quantitative science of the ear as an information receiver.

Evidence

The ability of our hearing system to receive information is determined not only by the qualitative relation between sound and impression, but also by the quantitative relation between acoustical stimuli and hearing sensations. With the advent of new digital audio techniques, the science of the hearing system as a receiver of acoustical information, i.c. the science of psychoacoustics, has gained additional import.ance. The features of the human hearing system will have to be taken into account in planning and realizing future acoustical communication systems in economically feasible projects: Each technical improvement in this area will be judged by listening and relating the result of listening t.o the cost. — Professor Dr.-Ing.
