Acoustic lens generates tunable 'sound bullets' for ultrasound applications

() —Scientists have developed an acoustic lens that produces pressure pulses that are so intense they.
() —Scientists have developed an acoustic lens that produces pressure pulses that are so intense they're called "sound bullets." Although they are too high-pitched to be audible to the human ear, the sound bullets could have a variety of uses such as in medical ultrasound, underwater mapping, and other high-intensity acoustic applications.
