a new way of thinking about time and space ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ by Rob Bryanton --author and research scientist David Jay Brown says: "one of the most brilliantly-conceived and mind-stretching books that I've ever encountered". --science fiction author Greg Bear says: "a fascinating excursion into the multiverse - clear, elegant, personal and provocative"
When the brain processes input from the auditory nerve, it tends to reject any continuous noises which do not change–like, for instance, the noise of the air molecules in the room banging into each other, or the sound of an air conditioner. In other words, for our consciousness, the noises (or smells, or continuous aches and pains, and so on) which cease to change, will cease to exist because the brain stops them from being considered for processing. When we listen back to the tape recording, we are hearing what’s really in the room, without the phase reversed noise cancellation the brain uses to remove those continuous noises. Now, when the internal mechanisms of the ear are damaged, usually through exposure to excessive sound levels, we end up with an imbalance, where the brain is correcting for frequencies that are no longer coming in. This manifests itself as tinnitus, or “ringing of the ears”. It turns out that the ringing we hear is not from the ears, but from the brain itself, as it attempts to cancel out particular frequencies that are no longer coming in from the auditory nerve.
