Guys The information you've started to collate is great, I'm wondering if we could push it a bit further and see if we can build a better picture.
Questions i'd like to add (if possible?);
Has the noise got worse over time (or constant)? What tension have you got the belt at? Is the belt alignment true (as far as you can tell)?
As Chriss99 says noise is subjective, vehicles that leave the factory are found to be acceptable / within our parameters during road test.

This is a good idea can I suggest we all measure the belt tension the same way. Perhaps by putting a straight edge along the underside of the drive belt and then measure the upward deflection in the middle of the belt, by using only light finger pressure. The alternative is to measure the twist but it is more difficult to measure angles accurately.
Also can we add is it noisy all the time or only when hot, mine is not noisy until about an hour of motorway running.
