Abstract
The fluctuations of a response signal during acoustic cavitation in water in an ultrasonic field were studied by photometry of the transmitted laser radiation. In a broad range of frequencies, the spectral density of photocurrent fluctuations exhibits the 1/f behavior and their amplitude distribution function has a bimodal character. Coarsening of the scale of the experimental time series makes the bimodal character more pronounced and reveals the scale invariance of fluctuations.
