In a very extensive research they have done here at
the acoustics department (which I understand is one of
the three main acoustics research departments in the
world), they found a few facts. The test was done to a
large number of people, and the notes were played one
after the other, not at the same time.
The area where people can hear the most difference in
pitch is about 3,000hz. The difference is even as
small as 5 cents. From there up or down it gradually
decrease. For example, around piano middle C people
can hear only about 10 cents difference. The highest
and lowest notes obviously you need a much bigger
difference. The test also proved that it is almost
exactly the same for all people.

Even from the best players in the world I sometimes
hear out of tune notes. No one can play 100% perfect
all the time. The result she says of 2-10 cents for
the better players is very logical.
