Hi Guys,
Just my two penn'orth so don't let it start the aggro going again, but isn't it a case of the interface between the organic and the inorganic, or between the live and the dead.
Put another way, if everyone's ears were physically and organically identical in every way, we would all hear the same sounds in the same way and report the same findings but, given that no two pairs of ears are ever identical in any way (let alone the fact that any two ears on any one person can be reliably said to be identical), we are all going to hear things differently. The sounds may measure identically on the outside of the ear but once they enter the ear canal things begin to change. So it must all be subjective and nothing else matters - the only thing that all of us are really interested in is how it sounds (or measures if you prefer) between the ears.
Pretty obvious really - why did I find the need to post it?
Cheers,
