Additional Information

Surround sound

Sound that consists of three elements:

direct sound, early reflected sound

(early reflections) and reverberative

sound (reverberation). The acoustics

where you hear the sound affect the

way these three sound elements are

heard. These sound elements are

combined in such a way that you can

actually feel the size and the type of a

concert hall.
