What is the difference tone from noise?

That would entirely depend on your definition of 'noise'. Some refer to 'noise' as Britney Spears music. Others, noise can be 'white noise' which is static or fuzz magnified on the audio feed.

Tone is best understood by clarity. Listen to a speaker playing any type of audio, put a pillow over the speaker, the difference you hear is a difference in tone. Tone is usually the contrast between treble and bass zones on the EQ equalizer.
