Abstract
A method for guiding, controlling or warning people, particularly for controlling and guiding people to a desired route, e.g. an emergency exit, in a dangerous situation, in which method, a person is guided by means of audio sources. In the method, audio sources (1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h) arranged successively at a distance from each other are activated to produce sound, in which the audio sources successively arranged in the space guide the direction of an exit route by producing an audio signal with the audio source against the travel direction of the guided route (6).
Claims21
A method for guiding, controlling or warning people along a desired travel route leading to a specific point on the route,
- the method comprising:
- arranging first audio sources successively at a distance from each other along one or more linear travel directions in the desired travel route leading to the specific point, and
- activating each of the first audio sources to produce a directional audio signal which is communicated directly against each of the one or more of the linear travel directions of the desired travel route leading to the specific point on the route,
- the method further comprising:
- locating a second audio source adjacently to specific ones of the first audio sources located at each of the specific points on the desired travel route which requires a special action, the specific points of the route requiring the special action including an exit, a door, or a staircase, and
- causing each of the second audio sources at the specific points requiring the special action to produce a second sound signal which is directed straight downwardly from above, thereby distinguishing the second sound signal, which is directed downwardly from above, from the directional audio signal of the adjacent first audio source, which is communicated directly against each of the one or more of the linear travel directions.
A guidance, control or warning system for controlling and guiding people along desired travel routes leading to each of several exits at a site,
- the system comprising:
- first audio sources arranged successively at a distance from each other which, when activated, are arranged to guide people along one or more linear travel directions in the desired travel routes leading to the several exits,
- wherein each of the first audio sources producing a directional audio signal which is communicated directly against each of the one or more the linear travel directions of the desired travel routes,
- wherein the first audio sources are arranged successively in the desired travel routes to guide the people, to the exit nearest to each of the people.
A guidance, control or warning system for controlling and guiding people along a desired travel route leading to a specific point on the route,
- the system comprising:
- first audio sources arranged successively at a distance from each other which, when activated, are arranged to guide the people along one or more linear travel directions in the desired travel route leading to the specific point,
- wherein each of the first audio sources producing a directional audio signal which is communicated directly against each of the one or more the linear travel directions of the desired travel route,
- wherein the directional audio signals of two successive ones of the first audio sources, which are communicated directly against each of the one or more the linear travel directions of the desired travel route, are made to be distinguishable from each other by altering a frequency of at least one of the audio signals.
