son(o)-

Also soni‑.

Sound.

Latin sonus, sound.

Sonography is the analysis of sound into its component frequencies; it can also be a shortened form of ultrasonography, in which ultrasound is used to image an internal body structure or a developing foetus. A sonobuoy is a buoy equipped to detect underwater sounds and transmit them by radio; sonoluminescence is luminescence excited by the passage of sound waves; a biological sample is sonicated when it is subjected to ultrasonic vibration to fragment its parts. Something sonorous is capable of producing a deep or ringing sound. The usual adjective relating to sound is sonic; sonics is the study of sound waves.
