And as we get older this thing called 'recruitment' means we're less able to recover the remaining information.Basically, "recruitment" was thought to mean that inner hair cells (part of the organ of Corti) were being recruited from around the "dead" one. This turns out to be wrong, but the name remains.
What it does mean is that sensation/loudness starts at a higher intensity (SPL) than "normal" and grows much faster to "normal" loudness.
(Loudness is internal variable, intensity external variable. Their relationship is rather more complex than a few words expresses.)
Basically, recruitment means that you can use less of the signal for understanding speech, for instance.
There is also bandwidth loss in hearing, which also eventually looses information.
It's far from a simple subject. Perhaps a thread started at the top of the page would be good if you care?
