The hair cells are half-wave rectifiers and trigger on the positive
zero crossing. They can fire, at fastest, about 1000 times a second.
So, at lower frequencies, the hardware is in fact transmitting a
mostly-phase-locked response to the incoming signal. This is part of
how low-midrange frequency sounds are localized.
Above 1000Hz the firing pattern becomes more like a power integral and
phase information is ~discarded. At low frequencies, it appears that
the neural hardware only pays attention to phase in the sense of
comparing phase offset between the ears. The transition is gradual.
So the ears hear absolute phase < ~ 1000Hz but it's not clear absolute
phase is actually passed up the perception chain.

Simple t-test should do it :-)
