, PARAGRAPH 1
Soundis the vibration of the air. It occurs at a sound
source,because something is vibrating.
The distance of (e.g.) the head of a drum
until the resting position, you call the diversion.
See the image (this is not a drum, but a
schematic drawing of two vibrations).
The greater the maximum deflection, the
the greater the sound intensity (how loud the sound
is). The faster the (skin) vibrates, the higher the tone
(how high or low the sound sounds).
The sound therefore comes from a sound source. The vibration
travels through a medium (the aire.g.).Then it reaches a receiver
(your ear). You then hear the sound. There is a small diagram that
goes with this:
SOURCE → MEDIUM → RECEIVER
(drum) (air) (ear)
In a vacuum cannot be sound, because there
is not a medium. The air is sucked out.
by the device to the right of it, there is then
so no more medium causing the vibration
can move. This is the proof that
sound always needs a medium.
A sound box(e.g. a guitar) is a hollow front
throw that the vibration of a sound source over-
takes and strengthens him.
How does amicrophone?
When someone sings, the sound (the vibration) goes to the
microphone. It converts it into an electrical signal and
that goes to the amplifier. He amplifies the sound, that
then to the speakers go.They put it
back into sound. And the amplified sound are heard
people who listen to it.
