Audio guide or audio tour
A recorded message to guide a viewer through a museum exhibit. Also called audio guides are electronic devices rented from a museum, either held like a telephone to an ear, or, as shown, earphones are connected to a player carried over a shoulder. MP3 players have become increasingly common means of delivering audio tours. Podcasts are made either by the museum's staff (and such companies as Acoustiguide and Antenna Audio) or by others. Some podcasts can be downloaded from museums' Web sites.Also see design, music, and new media.
