How to compare pitch of different sounds?
Pitch of Sound
This depends on the frequency of vibration of the waves. If the frequency of vibration is higher, we say that the sound is shrill and has a high pitch. On the other hand, if the sound is said to have a lower pitch then it has a lower frequency of vibration.
How do you measure Audio loudness?
The most effective way to measure loudness as it relates to mastering is with the unit LUFS or Loudness Units Full Scale. The integrated LUFS unit considers loudness over time, as it relates to various frequencies and how the human ear perceives those frequencies.
What happens to the loudness of the sound as you increase the distance away from the source?
As distance from the sound source increases, the area covered by the sound waves increases. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
