3. What is sound
vibrations that travel through the air, sound can be heard when they reach a
person's or animal's ear.
4. Acoustics
Every room has different acoustics, when recording sound in a room the sound
will reflect of the objects such as sofas and tables. The harder the object the
more it will reflect. In music studios they put panels on the walls which are
made out of foam. This absorbs and breaks up the sound instead of bouncing it
around the room. Also having a smaller room helps kill the sound as the sound
has less time to bounce off surfaces.
5. Reverberation
Reverb is the time it takes for the sound to die out. For example when you
shout in a open place like a mountain, the sound you create will continue for a
while as an echo. But in a small room it will die out quicker as there is less place
for the sound to bounce around.
6. Exterior acoustics
Atmosphere is where the recording is going to be happening. It is important
that you know where your recording. For example if you wanted to record a
scene in a film on the motorway, you couldn't film that in a forest as the
background atmosphere is different
When recording with a microphone outside using a windshield is an important
method to avoid wind interruptions.
Unwanted ambience is background sounds, which should not be a certain
recording. Unwanted noise comes from the busiest environments such as bars
and main roads.
7. Simulated acoustics
Simulated acoustics are effects that people put on the sound. For example
people in music studios purposely put the panels on the walls to absorb the
sound so it is quicker, but choirs in churches like the sound so they leave the
room and have the sound how it is .
