There are noises that give you a heightened sense of awareness, for example a lighter striking (inevitably for a candle when my Master strikes it) always gets me, even if it is just someone in the pub lighting a cigarette.

All of these things are ten times as effective when used in conjunction with sensory deprivation. The sound of the door to our cellar (our 'dungeon')opening when I am bound and blindfolded down there is something that sends tingles running through me...
