I've often wondered this. If somebody speaks into your ear, you do not hear
the pop you often get on a microphone in the same position do you. Likewise
when listening to music in a hall with your ears and then over headphones
from a set of mikes you notice the echo on the latter but not on your ears.
People say its the way the brain processes the sound, but if that is the
case maybe now we can actually emulate this in some way for recording?
No I don't mean going back to a close miked up every single instrument and
a mixer you need to be Twizzle to operate.

Ears are pressure transducers. This means that the ear drum almost
doesn't move when sound hits. A blast of air from a pop has very
little pressure, but a lot of velocity. Any microphone that isn't omni
will respond to air velocity - it is a combination of velocity and
pressure response that sets directivity. All pressure is omni, all
velocity is figure 8. A mixture of the two is one of the many flavours
of cardioid.
