Why a sound is produced when a fluorescent tube breaks?

Why does a big  sound come when tube-light breaks?

(Question was posted by Vishwesh)

Answer: Every sound is produced by some vibrating bodies. In this case it is air surrounding the tube which vibrates.

Broken Tube LightInside the tube-light there is partial vacuum. When it breaks, the air surrounding the tube suddenly rushes into the vacuum and starts vibrating and thus produces the sound.
