　　there are four major ways sound is affecting you all the time, and i'd like to raise them in your consciousness today. first is physiological.

　　it's not just unpleasant sounds like that that do it. this is surf. (ocean waves) it has the frequency of roughly 12 cycles per minute. most people find that very soothing, and, interestingly, 12 cycles per minute is roughly the frequency of the breathing of a sleeping human. there is a deep resonance with being at rest. we also associate it with being stress-free and on holiday.
