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.

Science definitions for sound

sound

1
[ sound ]

A type of longitudinal wave that originates as the vibration of a medium (such as a person's vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density. The loudness of a sound perceived by the ear depends on the amplitude of the sound wave and is measured in decibels, while its pitch depends on its frequency, measured in hertz.
The sensation produced in the organs of hearing by waves of this type. See Note at ultrasound.

A long, wide inlet of the ocean, often parallel to the coast. Long Island Sound, between Long Island and the coast of New England, is an example.
A long body of water, wider than a strait, that connects larger bodies of water.
