Austrian acousticians have figured out how to holographically project sound
Franz Zotter and Matthias Frank, acousticians from Austria’s Institute of Electronic Music, have nearly perfected a new technology that holographically projects sound.
A spherical array of microphones built around a musician allow the two acousticians to capture every angle of sound emanating from the instruments being played, recording the way the sound waves bounce off the walls in order to create a 3D sonic image. Once the image is captured, they then feed it into the corresponding speaker which they dub an “icosahedron,” which can project the recording with perfect accuracy into any room it’s placed in.
Those working with this new array describe the sound projection as feeling as though you’re taking place in a live concert, but without the band present. As the technology is still within its development stages, various facets of its usefulness are still being discovered. Thus far, virtual reality and gaming are emerging as the most immediate benefactors as coders continue to implement more acoustic aspects to create a fuller and more accurate painting of reality.
The Institute of Technical Acoustics in Germany have also found interest in it as well, according to Zotter. Together the two groups are looking to experiment on the production side of its use, projecting sound into different venues to better plan acoustics and to allow musicians to hear what their playing sounds like in a place they have not performed before.
