We are born with mostly noise and very little signal. The most we can hope to achieve is the S-N performance of analogue soundmixers. Our 'circuitry' adds a hell of a lot of noise because it is a function of neural connections.

And don't go saying that digital systems can achieve greater S-N ratios, because they only do that by slicing up time into boxes and fooling the mind in the same way as the phenomenon of Persistence of Vision fools the relevant parts of the 36 (odd) visual projection systems in the brain that we know about.
