Difference between SOUND WAVE | PITCH | TONE and NOISE
Most
of the sounds we hear are brought to our ears through the air. A moment of
object causes a disturbance of the air molecules near the object so that the
disturbance itself becomes a thing that moves through air, thus a SOUND WAVE.
When the sound wave is produced regularly
If
the sound wave is produced regular, evenly spaced, so that we hear as “PITCH”. If the moment of disturbance is regular,
fast and vibration, then the sound waves are also regular. We hear such regular
sound waves as “TONES” that sound with
particular “PITCH”.
What is "NOISE" then?
When
we hear sound that are random, disorganized and lots of wavelengths. These are
the kind of sound we call “NOISE” (Lärm).
In terms of science, noise refers to “CONTINUOUS
SOUND” (Geräusch). When the continuous sounds are too loud
and disorganized then they become noise.
Language
has a lot in common with music. The purpose of language is the whole cosmos of
human ideas and transmission of emotion by words and symbols.
