These results may out may not apply to humans. I wonder what frequencies were used in the experiment. While anything higher than 20 kHz is beyond humans hearing range and is called ultrasound, mice can hear sounds as high as 79kHz.
From the article:
Parameters for the ultrasound delivery were 0.7-MPa peak rarefactional pressure, 10-Hz pulse repetition frequency, 10% duty cycle, 1 MHz center frequency, and 6-s sonication time per spot.
