Introducing NICT's R & D results related to disaster prevention
Multiple sound spot synthesis technology
A sound field control technology that can creates different sounds at different zones
Although sound waves normally spread in all directions, this technology uses multiple loudspeakers to cancel out unwanted sound waves and make them inaudible while synthesizing a sound only to a specific area. It is also possible to synthesize different sounds to multiple areas. This technology can be applied to create "new sound spaces" in various fields such as exhibition booths, entertainment facilities, automated vehicles, and hazardous areas.
It is expected to have a wide range of applications in the field of disaster prevention in the future, such as evacuation guidance in multiple languages in the event of a disaster or delivering voice only to specific people without contact for preventing infectious diseases.
