| Outline of Final Research Achievements |
In this study, we proposed a remote sensing technique of sound field that is a strict measurement method of sound field using scale technology and laser techniques. Specifically, to realize sound pressure and the particle velocity remote sensing using a laser beam, we made the 3D sound field remote sensing system with combining the acoustic lens, reflector and photodetector. We can achieve the recording of sound field and intangible cultural heritage, and also achieve a small communication aid to get clearly the long distant sound.
