1. Sound is energy that travels in waves through
air,water,or other subtances,and can be heard
when they reach a person’s or animal’s ear.
2. There are two necessary elements for
sound production;a vibrating material as
the source of sound and a medium in
which sound can travel.An object is able to
produce sound when it is allowed to
vibrate.
3. Art of recreating everyday sound
effects.foley is unique sound effect
technique that involves creating sound .
4. The highness or lowness of sound is called
pitch .Pitch is the property of sound and
especially a musical tone that is
determined by the frequency of the waves
producing it.
5. Loudness is related to amplitude; that is,a
loud sound is expected to have big
amplitude.
6. The higher the pitch,the higher isj the
frequency.
The thinner the vibrating material,the
higher is the pitch that it can produce.
A shorter matterial that is allowed to
vibrate produces a higher pitch.
