The presentation discusses the aspects of sound and how useful it is. But yeah this is not a physics presentation. It basically discusses applications of sound in video.

4. Sound Defines Picture
 Audio is dominant and it also
determines the subjective
meaning of the image.
 The same visual with
different audio can give
different meanings to the
viewer.

5. Sound Parallels Picture
 Neither oral nor visual element is dominant. They only compliment
each other.
 What you see is what you hear.

6. Picture Defines Sound
 Picture helps define
sound by calling attention
to particular actions or
images.
 The sound keeps
changing/evolving as the
picture changes/evolves to
bring the audience closer
to reality.

7. Sound and Picture
defines Effect
 The aural and visual
elements are different yet
complementary.
Together they create an
impact that neither could
do alone.
 Neither sound nor
picture is dominant, and
although they are
parallel, they are
reinforcing each other to
produce a cumulative
effect.

8. Sound Counterpoints Picture
 Both elements contain unrelated information that creates an effect or
meaning, not suggested by either elements alone.

9. Conclusion
 Sound can alter Moods.
 Sound influences how we re act to picture.
 Sound is the most basic necessity of any production.
 We can have long running successful production only with sound and no
visual, like in the case of radio, but the reverse is not possible.
