Achieving "delivering sound only to the people in that location" with super-directional technology, which is difficult with general speakers.
Conventional speakers diffuse sound over a wide area, making it difficult to deliver sound only to people in specific locations within exhibition facilities and commercial spaces. By adopting super-directional speaker (parametric speaker) technology, we have built a system that delivers sound exclusively to specific areas or individuals. Through acoustic characteristic evaluation and adjustments, we have achieved selective sound transmission to designated areas. This contributes to immersive audio experiences, such as audio guides in front of exhibits in museums and exhibition facilities, promotional sound in stores, and individual audio in hospital waiting rooms.
