| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a preliminary study of acoustic scene analysis with sound-to-light conversion devices ``Blinky'', which we developed. A Blinky is a small battery-powered device consisting of a pair of MEMS microphones and four LEDs connected to a low-power processor. The device translates sound power recorded by the microphones into brightness of the LEDs. Several Blinkies are distributed in space and the acquisition of all their light signals is carried out at once with a video camera, allowing to monitor sound power over a large area. In this work, we describe a few preliminary experimental results of the application of Blinkies to sound scene analysis. Specifically, 1) an outdoor scene with pedestrians and vehicles and 2) an indoor scene in an office with people chatting and eating lunch are filmed with 18 Blinkies used. The Blinky signals are extracted from the video and various analysis are performed, including time-frequency analysis and scene recognition. |
