Who has the loudest roar?

Can a sperm whale kill you with sound?
Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … “These clicks are so powerful in the water that they can blow out your eardrums easily, and they can actually vibrate a human body to death,” he said.
Are Loud sounds harmful to humans?
Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die. The hearing loss progresses as long as the exposure continues. Harmful effects might continue even after noise exposure has stopped.
Why is 194 dB the loudest sound possible?
Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. … Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.
Can 200 decibels kill a human?
Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
What animal has a loud scream?

What’s the loudest animal in the world?
blue whalesAlthough blue whales are considered by most to be the loudest animals, there are many ways to measure loudness. At pure decibels, the sperm whale is louder than the blue whale because its clicks have been recorded at 230 decibels.
How loud can a human yell?
Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears! You should also have found sound levels drop off quickly as you get farther from the source.

Has a killer whale ever eaten a human?

Has a whale ever swallowed a person?
