Hi, Gregor. I mentioned the cochlea shrinking because it happens to people in general (though I don't know to what extent), but is not widely known about. So it happens to tuners as well, but, like people in general, most tuners don't have "perfect" pitch, so pitch recognition is not tested, and changes are not noticed. I don't know whether there is a direct relationship between the cochlea shrinking and the perceptual acuity shrinking (sensorineural impairment). But since tuners don't use an internal compass to measure pitch, cochlear shrinkage alone probably wouldn't affect tuning much, if at all. -Mark Schecter Gregor _ wrote: > > Is it not the other way round (not the cochlea shrinking but the > perception)?
