Abstract
In order to guide a person along a path, audible acoustic signals are used, which are generated by signal generators arranged in an area. The person can orient themselves in the area using these acoustic signals. As the person moves along the path towards a destination, the signal generator arranged next in line on the path generates an acoustic signal, in which direction the person can then move. A signal generator generates an acoustic signal of this type, when it receives a control command from a mobile device carried with the person or from a control device.
