Intense orange Na^* emission was observed in different spatial locations from blue emission during multibubble sonoluminescence (MBSL) in sulfuric acid. The color change from blue to orange observed along the streamer in the filamentous structure of a bubble cloud in both ultrasonic horn and cleaner. By comparison of MBSL between an ultrasonic horn and a cleaning bath, 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.
