We have to get away from mechanical transducers. When we are able to directly stimulate the auditory nerve,

then the major problems of room / transducer interaction and distortion will vanish.

There is an insurmountable divide between live and reproducing live in the home. The hope of closing that particular gap is quite laughable.
- I don't think it's laughable. It is only a question of time and technology; do you really think that say 300 - cfb 10:57:09 07/01/12 (1)
  years from now the same crude tools used today will be all there is to record reality?

First, all natural sounds are heard via the transformations of the external, middle and inner ears and, so, bypassing them by direct auditory nerve stimulation would only require that we simulate their effects anyway.

Second, in order to stimulate the auditory nerve electrically, we would still need mechanical transducers to encode the sound into electrical signals.
- What about plasma microphones or recording the nerve impulses from a human ear at some point in the future? - cfb 11:00:27 07/01/12 (1)
  We have to go beyond a vibrating mylar or paper membrane and a coil of wire if we wish to replicate reality at some future date. We must be able to record all the neural data going into the brain and then reproduce that in another individual. Take the current crude cochlear implants or auditory brain stem implants and extrapolate a hundred years of development with nanotechnology. Instead of today's mere couple dozen electrode array, implants would have a million electrodes in the device array. Where every individual nerve cell could be stimulated.

    If the starting point is a live acoustic performance, the energy produced is mechanical. So, if your end-point is direct electrical or magnetic brain stimulation, at least one transduction step is necessary. What one does in between is moot.

Most of the noises that we hear in this world are created by mechanisms. Should crickets and frogs stop what they now doing and learn how to telepathically beam noise across open space and into our eardrums? How do we "directly stimulate the auditory nerve" without the aid of mechanical transducers?

If one can tolerate a large physical size, one can also use directivty to make he room problems largely vanish but this still leaves the problem of capture / recording and the loudspeaker not being faithful to the input signal.
- That's just the point, we must advance beyond the current electromechanical loudspeaker technologies. - cfb 11:05:59 07/01/12 (1)
  Let's say someday being able to beam the signal directly into the brain bypassing sound waves entirely.

    WE use our ears and brain to hear, they work in 3d too, all we need to do is present them with something close enough to fool you into believing it was a different acoustic environment and this can be done.
    
    The way we record and the fact that we for the most part fully ignore how sound radiates and how we hear is what is limiting what we have now and that driven by the common denominator in the market.
