OREANDA-NEWS Specialists from various companies have long been engaged in the development of personal sound projects, however, representatives of the University of Sussex, England, were the most quick. They used special acoustic lenses made of materials smaller than the sound wavelength to create their device. 

This technology allows a personal sound projector to broadcast audio messages to a specific person at a distance. The device will create in front of it a sphere with a diameter of 6 centimeters, transmitting a message. The novelty adapts to the person, his height, body position and movement so that the sound object is always in front of his face. 

Another success of English scientists is that they managed to create an inexpensive personal sound projector. Its acoustic lenses are printed using a 3D printer, its cost is $120. 

The developers of the device see great potential in it and note that it can be used almost everywhere: from receiving personal messages in public places to creating high-quality sound in movie theaters.
