    I hear digital voices in my head. Can you hear them too?? I'll pluck one of my ear hairs out and give it to you so you can hear what I hear. It sounds like marshmallows and fingernails on a chalkboard....in stereo!


    ....and I f*cked Keiko......

    Interesting thought, but no.

    There are no numbers (digits, 0s and 1s) being transmitted to your ears or in your head.

    You may have better luck thinking of it as an anaolgue signal.

    Any audio signal transmitted, be it digital or analog at source, will always be just a cluster of vibrations from said source to the ear of the translator.

    In an electrical sense there are no "numbers" being transmitted in any digital signal, it's simply how we choose to interpret digital signals. A digit of "1" means "on" and a digit of "0" means "off". It's not like the numbers zero and one float across the wire like a Sesame Street cartoon :D
    If you will it, dude, it is no dream.

    I think in binary. But I count in BCD.

    It's easier to think of it as analog, but the hairs in your ears don't say, "well i hear a 80hz signal" and then send 80hz information to the brain. But rather, they send an electrical signal down dendrites and axons. Eventually, ions (transmitters) will jump across the synaptic clefts in synapses and continue this process until the electrical signals reach the correct centers in the brain. Since the amount of transmitters is discrete, this means that the signal is discrete, not continuous.

    Similarly to how your eyes work. There are only X amount of rods and cones. And hence they cannot generate an infinite resolution. There is a limit.

    Although, there are probably so many specialized cells in your eyes and ears, that you may consider the images and sounds you hear to be analog for practical purposes.

    For simplicity sake, I left out A LOT of information to how cell signaling works.

    Lint,ear wax, and toe cheese are just part of your roomtreatments when doing critical listening.:)


    Do any of you think altitude could play a part in how we hear things as well? what I mean is could my rig sound completely different? say in Florida?

    But then again if it sounds different it may not be the altitude it could be the electrical grid being feed to my rig in florida.

    I would assume that some electrical grids are better in some parts of our country.

    Just thinking here...

    It's not really an electrical signal like in a wire. The electrical signals are a result of the cellular membranes depolarizing. When a neuron depolarizes neurotransmitters are released into the synapse between it and another neuron which opens chemically gated protein channels in the membrane of neuron #2 allowing for an influx of positive ions and consequently causing the second neuron to depolarize; passing along the message.

    You're right that there's no actual message being transmitted other than in an on or off fashion. Our brain sorts out the information and decides what we should feel based on the type of neuron firing, it's position in your body, the amplitude of depolarization and the frequency.

    The carbon based electrochemical mechanical things are too troublesome! They always wanted to know how things work and how they are made of. I simply tell them friction and pressure is all it takes.
    Trying out Different Audio Cables is a Religious Affair. You don't discuss it with anyone. :redface::biggrin:

    Point taken, but digital as we know it or as used in this context implies binary. In reality it would be more like the Fibonacci sequence. :D
