Presbycusis (age related hearing loss) is the gradual loss of hearing that occurs as people get older. Presbycusis involves progressive sensorineural hearing loss.
Through a new multi-institutional study, researchers have discovered that Egyptian fruit bats (Rousettus aegyptiacus) experience loss of hearing as they age, just like humans.
