Detection of acoustic cavitation using subharmonic spectrum analysis

In this study, the cavitation activity induced by the ultrasound irradiation on exposure parameters has been measured by subharmonic analysis. Experiments were performed in a 1 MHz field. The effect of duty cycles changes with 2.2 W/cm2 intensity and acoustic intensity changes in continuous mode on subharmonic intensity were measured. The correlation between fluorescence intensity of terephthalic acid chemical dosimetry and subharmonic intensity analysis were analyzed by Pearson correlation (p
