Although it is in very early stages of research here is one likely application:

The researchers have already used the technology to significantly improve the efficiency of an advanced nebuliser device developed at RMIT, which delivers medicine directly to the lungs.

We’re looking forward to hearing more no pun intended 😉

And this is just a cool related physics video showing the physics of sound.

This Eureka.in Physics video shows how sound travels through the various states of matter, significance of Vibrations in the traveling of sound energy and the various type of sound waves. It also discusses about the measurement of sound and the concept of echo.
