i was in the woods, alone....it was very silent that mid-afternoon, as the insects and birds seemed to rest from their activities....the noise floor dropped and my hearing reached into the silence, becoming more focused and analytical.....new sounds, that heretofore i had been unaware of, made their presence to me....and more detailed information about the sounds....and as i listened with more conscious attention....i was frustrated as i reached the level of hashy, grainy ringing of tinnitus and the noise floor of my hearing.....it was like enlarging a digital photograph until its components become abstract.....and it is not possible to imagine the larger picture from a view of its parts.....
