With all the automatization of the production the directional sound brings into this sector great revolution in communication on production lines or manufacturing processes.

Today it is normal that most of the production is handled by automatization, but there is always human labor as well and because of this we are still trying to achieve the best possible communication between machine and human. Until now there is only the visual input, f.e. the next vehicle is approaching etc...

If the human wants to work effectively, he can't, because he attends to visual communication and at this time he can work only with restrictions. If we would use the sound information instead, the worker can steadily dedicate himself for work.
