Thousands of marine species from microscopic zooplankton to the largest cetaceans rely on sound for survival and many have ...

Might it also be possible, then, to use acoustic waves to disrupt the electromechanical sensors that drones require to fly?

We can’t hear all levels of sounds. Sound waves with very high frequencies are called ultrasound and our ears can’t detect them. Ultrasound waves have multiple uses including: detecting ...

The process is very similar to ultrasound imaging. However, the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...
