111 高速移動体の音源可視化システムの開発

概要

論文の詳細を見る
Visualizing and finding exact noise source locations on the surface of a moving vehicle is inherently difficult. A two-dimensional microphone array with high resolution was designed and synchronized with a visual sensor to acquire a picture of a moving source during a measurement. Experimental results show that a spiral array gives better resolution for moving cars and trains. Noise sources were visualized within 50 cm at 1 kHz with a microphone array 10 m away from the source.
