Abstract (in Japanese) (See Japanese page) 
(in English) Intense orange Na* emission was observed in different spatial locations from blue-white emission during multibubble sonoluminescence (MBSL) in sulfuric acid. The color change from blue-white to orange was observed along the streamer in the filamentous structure of a bubble cloud in both an ultrasonic horn and cleaners. By comparison of MBSL between an ultrasonic horn and a cleaner, the locations of Na* emission were deferent. The Na* emission, however, may occur at the location where the acoustic pressure was relatively low in both cases. In the ultrasonic horn case, the Na* emission only appeared less than 30 % ultrasonic power of full range. Therefore, the sonochemical fields by ultrasonic horns may normally utilize cavitation bubbles without Na* emission.
