I believe it is the pitch that changes when the loudness of a note changes
It doesnt
Loudness of sound is measured in decibels (dB).
Tiny hairs inside the Cochlea (see related link)act like little 'tuning forks' which will sympathetically vibrate with different frequencies (pitches) of sound. There are nerves associated with each hair, which transmits information to the brain.
People's perceptions of sound intensity is known as loudness.
The changes of stat are physical changes because the stat is similar to the physical changes.

When the loudness of a note increases, the perceived pitch does not change. However, if the loudness of a note decreases significantly, it may start to sound quieter and could appear to lose its pitch as it becomes less audible. Nevertheless, the actual pitch of the note remains the same.
The amplitude is essentialy the volume (loudness).
When the amplitude changes we hear the loudness changing.
pitch is the tone of the note/ssong. (high or low) intensity involves speed, loudness, business and strength in a piece
Why I change to the loudness level of a speaker with my pc, the level of vibration on the speaker changes. But sometimes I find the vibration is much bigger but the decibel measured with a tablet does not change as much. So why is this?
The level of the note might give two meanings. The more probable meaning is the pitch, its frequency. It may also denote the 'loudness' of the note: technically it is called 'velocity'.
are there changes in the note when you plucked the stretch band
Volume is the intensity of loudness or softness that a musician plays a passage or a single note of music.
The loudness of notes are determined by the speed and intensity of the air being blown through the instrument. The harder and faster you blow the louder the notes will be. Just remember to blow clean and not cause a squeak or unpleasant sound.
The amplitude of a sound wave is perceived as the sound's loudness.
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".
