Additional Information
Surround sound
Sound that consists of three elements:
direct sound, early reflected sound
(early reflections) and reverberative
sound (reverberation). The acoustics

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.
