Owls hold the key to better hearing..

Barn owls do not appear to suffer hearing loss as they get older
German researchers have discovered that barn owls, which rely heavily on their sensitivity to faint sounds in order to hunt, do not suffer any significant hearing loss even when they are elderly.

Georg Klump, professor of animal physiology and behaviour at the University of Oldenburg, said it was likely that the ancestors of humans and other mammals had once had a bird-like capacity for repairing their cochleas. This means it may be possible to switch the relevant genes back on with drugs or other treatments.
