What do the three piano pedals do and how do they affect the sound produced by the instrument?

The three piano pedals are the soft pedal, the sostenuto pedal, and the sustain pedal. The soft pedal makes the sound quieter, the sostenuto pedal sustains specific notes, and the sustain pedal makes all notes ring out longer. These pedals affect the sound by changing the volume, sustain, and resonance of the notes played on the piano.
