A-Volute comes up with a revolutionary tehnology called Nahimic Directional Sound. Nahimic DS focuses the sound in one direction, so that it can be heard by a single person. Outside of this personal listening area, there is nothing to hear but silence.
To achieve this feature, we managed to confine the audio into a directional beam, by using acoustic waveguides. Our technology enables us to create an audio beam thanks to the combination of two principles: parametrical speakers and nonlinear acoustics. The ultrasound mask is taken off by the nonlinear acoustics, which turns the ultrasound [40-80kHz] into audible sound [20-20 000Hz] and only delivers the sound that is meant to be broadcasted.
Range: 25m. What makes this technolgy unique is its unequaled range. With a very limited sound attenuation the Nahimic Directional Sound technology allows to project the audio beam on surfaces placed far from the source.
