Abstract:A pair of properly functioning ears is of great importance for various common daily tasks. While the perception of speech is perhaps one of the most obvious examples, being notified by certain sounds like (fire-) alarms or traffic sounds can even be lifesaving. Therefore it is not surprising that hearing impairment may have a strong (social) impact. Typically, hearing problems will occur mostly with elderly people. However, due to the upcoming popularity of portable music-players, like the iPod, permanent hearing loss is currently also a problem for younger people.
