The Sounds of Sound

I think sound is such an interesting sense. Even as I sit here typing I hear the letter keys click and create their own music. I hear the buzzing of my electronics, the whooshing air from my air vent, the turnstiles clicking and the door opening and shutting outside my window. I hear footsteps on the stairs, knocks on doors and voices talking. We are never without sound. I think to be without it would be extremely scary and nerve-wracking.
