A common problem with promotional sounds in retail, audio visual displays at exhibitions and in public spaces, museums, visitor centres, airports, etc., is that any sound spills out into areas, which are not targeted. Together with all other sounds in the area, it creates a great melanche and noise pollution.
Hypersound soves this problem. The sound beam is carefully concentrated and directed into the area to be covered, such as in front of the display. At a distance the sound is not audible. This also creates an interesting curiosity effect, since passer's may perceive sound and than not. Causing them to stop, maybe go back and this way are directed to the source of the sound and the message. A great tool at relatively low cost.
