Experimental research into the cavitation noise spectrum in water solutions of high molecular weight polymers

The paper presents cavitation noise spectrum measurements results for water and a water solution of polyacryloamide with the 1.5 × 107 g mol−1 particle mass. Cavitation noise spectrum characteristics were shown for different ultrasound intensity, with different sonification times (at a constant ultrasound intensity) as well as characteristics which enable comparing particular sonification parameters.
