Subject: [Nature Recordists] Re: Very quiet recordings


these 'silences' aren't silent. What tends to happen is the extreme quietness 
combined with the listeners attempts to perceive it lead to a situation where:

1) on a psychological level, one accepts the definition of silence
2) on a physical level, the ears attempt to adjust to the surroundings & to 1)

the combination means that 'silence' is the surface perception. There are all 
kinds of sounds present, even in the disorienting stillness of the most quiet 
places on earth (such as deep caves or deserts) but, as is the way of us 
humans, it is easier for us to apply filters to our perception of what is there.

micro / macro listening to these places or recordings of them reveals a wealth 
of sound, all be it on a sometimes very subtle level.

it's amazing to perceive stillness & amazing to hear whats there at those times.
