At the beginning because of my Venezuela Phone Number List and my activities, I was a composer-musician, classical jazz pianist contemporary music and I worked on sound installations. In this context, there are often problems that arise: can we broadcast different sound content in the same room to be able to design a more spatial sound experience? At the same time, around 2006, I discovered by reading scientific journals the principle of its directional sound. With these 2 elements, I became passionate about the principle of channeling the propagation of sound in space. Concretely, it is a tunnel or a beam of sound which is created and when one

leaves this bubble of sound, one does not hear anything any more. So I started to take an interest in this subject. In 2006, I am 26 years old and I am a musician. Initially, around 2008, I went to see a doctor of acoustics at MIT in Boston for a few days, to talk about these questions. The researcher had developed a first enclosure with its directional. I was able to test the product, ask questions. This first product was really impressive, first of all because I was discovering the principle in life size. I also discovered all the limits because they were the first versions, unfinished products that were chirping in the air. It was very far from optimal and the machine was large. Following this meeting, I continued my investigations in France.

Where Is The Company At Now

I showed a product that I had brought back from the United States to researchers who were doing acoustics at the Langevin Institute in Paris so that they could give me their opinion. They found the sound to be ultra low, hardly audible. Despite all these problems, I told myself that it was interesting for making adventurous installations, for creating complex sound environments with sound zones. One of the first experiences I did was a sound journey entirely in the dark where we walked through the different sound beams. When did you want to start your business? I tell myself that no one knows this technology and that as it is, it was


complicated to use because the concept was not successful. It was therefore not yet possible to develop it in the public space to create more functional installations. So there was something to do, to try. The enclosure produced since 2019 is a square and the sound emitting area a hexagon. I created the company and launched the project in 2010. Initially, I have no experience in the trade, I have to learn the basics of what a business is. I am recruiting engineers and doctors to work on the subject, there are 4 of us at the start. The beginning is not easy, we are groping because the technology is very complex. In research, we discovered

What Are The Use Cases

many problems in acoustics and electronics in particular. We made a lot of prototypes until 2017. On the finance side, we were helped by the Public Investment Bank (BPI) and we also provided a lot of services for the R&D departments of large groups on multiple subjects such as signal processing. In 2017, we believe that our prototypes are quite successful and we produced several hundred parts with companies from Île-de-France. The objective was to confront industrialization and the market. At that time, I already imagine the market for public spaces because the need is simple. When I speak of public space, we identify 3 different

places: point of sale, point of transport, point of waiting. It is an open space where we cannot broadcast sound otherwise we pollute the whole space. The consequence is that the sound of the screens is silent, there is no sound feedback. Developing a sound beam is therefore of great interest. We sold this first production in 2017 quite easily. The prototype met the need on a lot of points. The sound level was louder than the first 2 prototypes developed by the Americans, the device was 4 to 5 times smaller in size. We also identified what was wrong. At the same time, we were working a lot with the automotive sector.
