synonym study for sound

1. Sound, noise, tone refer to something heard. Sound and noise are often used interchangeably for anything perceived by means of hearing. Sound, however, is more general in application, being used for anything within earshot: the sound of running water. Noise, caused by irregular vibrations, is more properly applied to a loud, discordant, or unpleasant sound: the noise of shouting. Tone is applied to a musical sound having a certain quality, resonance, and pitch.
