Using Sound to Create a Soundscape
Venues are typically created using general construction methods, illumination techniques, and in some cases fragrances and other such means. With the development of soundscape production, Yamaha adds acoustics and sounds as a new element in venue creation.
Imagine, for example, that you are in a forest. You hear the murmuring of a small stream in the distance, and above your head you hear the twittering of birds. When the wind blows, you hear it rustle in the trees. Perhaps you feel a little shiver, even though it's still summer. These sounds are creating a soundscape.
Principles of Soundscape Production
Soundscape production is a new technique that merges sound beaming technology — where a Yamaha array speaker generates movable beams of sound — with indirect acoustics technology and with the spatial audio expertise of the Yamaha Research and Development Department. Direct and indirect beams transform the entire space into an acoustic event. The moving beams generate shimmering acoustics, produce fascinating changes in the sound image, and create a natural-sounding and intriguing ambience. By using indirect sound—reflections off the walls—the system can make the speakers seem to disappear, or else can create the uncanny illusion that the speakers are located in impossible locations behind the wall, making the room seem larger than it actually is.
Types of Soundscape Effects
There are two main types of effects: indirect and direct. The indirect effects work by bouncing sound off walls and ceilings; the direct effects work by beaming sound toward the listeners while changing acoustic parameters such as clarity and depth. The combination of these two types makes it possible to create a soundscape through the use of sound.
Numerous effects are available, as enumerated in the listing below.
The system was used at Lexus International Gallery Aoyama to produce “space widening,” “space shimmering,” and “optimal ambience” so as to create an image of the Lexus brand through sound. The space widening effect creates the feeling of a wide-open, pressure-free space that symbolizes the Lexus brand; the shimmering effect generates a natural sense of continuous refreshment; and the optimal ambience sound is directed into the zone where customers and salesmen are bargaining, creating a space where discussions can be held in comfort and clarity.

At the Shin-Marunouchi H.P FRANCE shop (in Tokyo's Shin-Marunouchi Building), we use venue production to create the sense of being in a forest. At the same time, we also create the feel of a comfortable work environment. (Music Composer: Masato Hatanaka)
