This process, called cavitation, is very loud — Kathy Metcalf, the president and CEO of the trade association Chamber of Shipping of America, said it accounts for most of a boat propeller's noise.

As the propeller moves away from the bubbles, the pressure increases, causing the bubbles to explode in a cacophony of pops and hisses. The amount of cavitation is related to the speed of the object.

"Cavitation has been studied since the 1800s," said Pavlos Vlachos, ... And just like the bubbles that damage boat propellers, bubbles bursting near the brain could damage its soft tissue.

The risk of cavitation can be minimized through proper design of the propeller or impeller, but there are trade-offs that can reduce overall ship performance and speed. Quiet Movement JEAN ...
