Engineers created the loudest sound possible underwater

The power of sound on Earth has an upper limit — it is 194 dB in the air, 270 dB under water. The fact is that with

reaching these marks, the medium in which the sound waves propagate begins to break down and the sound cannot become louder.

That is what happened when researchers withusing an x-ray laser, they hit the water. When the water evaporated, it created a shock wave, which was then divided into zones of high and low pressure.

During the experiment, researchers found: as soon as the sound intensity exceeded a certain threshold, the water disintegrated and turned into small steam-filled bubbles, which immediately collapsed in a process called cavitation.

Previously, researchers from Harvard Schooltechnical and applied sciences for the first time used a semiconductor laser for transmitting and receiving radio signals. In the future, a hybrid electronic photonic device will create ultra-high-speed Wi-Fi.
