What more, this phenomenon is demonstrated by a tiny critter in the ocean, Mantis Shrimp. What is Sonoluminescence? Sono means sound, while lumen means light. The word literally means creation of light from sound, which may sound impossible , as it was to me in the beginning but there is scientific explanation to it.  Technically, it is a pulse of light, which is generated when a bubble collapse over itself. This bubble is generated by the sudden outburst of sound. It is basically a conversion of acoustical or sound energy into light energy which is part of nucleation, growth and collapse of bubbles in liquid. 2) Behind the scene There is more to it, the bubble generated during this process makes the surrounding water h...

Sound has whole spectrum vibrational frequencies to propagate energy through a medium. I was in a club once and what I considered loud noise was music to others.

It’s a matter of perspective from individual to individual. Though theoretically there is not difference between sound and noise both are vibrations in the medium like air, water or wood but What I perceive as music, you may consider it as noise.
