sound 1 (sound)

v. sound·ed, sound·ing, sounds

Free from disease or injury.

To probe a body cavity with a 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.
