Loudest animal in the ocean

The sperm whale (Physeter macrocephalus) produces focalized clicks that reach levels up to 230 decibels underwater, which is loud enough to burst a scuba diver’s eardrums. One of the deafening clicks lasts only 100 microseconds. The whistle of the blue whale (Balaenoptera musculus), which lasts from 10 to 30 seconds, can reach up to 188 decibels and can be heard for hundreds of miles underwater. By comparison, a jackhammer reaches approximately 100 decibels, and NASA’s Saturn V rocket, which blasted the first Apollo moon astronauts into orbit, reached up to 204 decibels.
