I've never heard what I consider to be a good explanation for this. However, I have noticed it in piano tuners as they get older. These are people with very extensive training in hearing out pitches. Their training is ongoing so long as they continue to tune pianos. Through the use of tuning forks, strobes, etc. these folks do get feedback as to their references for pitch but I have notices that treble end tuning tends to be shaprp by several cents and even bass end tends to be effected. Interestingly enough, I have not found the essential temprament intervals to be effected by whatever this is. On another note, I also see this in musicians. I've never seen anything to indicate why it should be sharp for some people and flat for others but sharp seems to be what I see the most. At one time several years ago I had started to investigate this and my initial findings seemed to indicate that pitch perception alteration might be more common in those most likely to have noise induced hearing loss.
