1.Acoustic systems for visitors

Guided tours are the most popular services in museums. Scientific personnel, specially trained guides are usually responsible for guiding visitors through the institution. In addition to this personal mediation, especially museums have access to acoustic guiding systems.
There is a wide range of offers and usages of such systems. The predecessor of these systems is the Walkman, which is still used by some smaller institutions. In most institutions, however, it has been replaced in the meantime at least by its immediate successor, the portable CD player.
Compared to compact cassettes, CD devices have greater capacity, quality, reliability and flexibility in information access, which gives visitors more freedom to explore the exhibition hall.
 
 
A further step in development is the digital audio guide. This device can be integrated with other services and provides new opportunities for museum visitors. For example, GPS technology makes it possible to offer an outside tour, eliminating the need to create and maintain interpretation panels. The device provides visual support (image and video sequences) to the text and narration (audio).
