Can the sound of a rocket kill you?
If you were anywhere near such a loud and obnoxious sound, it wouldn’t just rupture your eardrums… the sound energy could also potentially kill you. While the rocket is still loud even with the water spray, the sound energy is greatly reduced.
What is the loudest sound in the world?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
How many decibels can kill you?
150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB.
Why is 194 dB the loudest sound possible?
A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level and 0 degrees C. Thus, the sound waves are creating vacuums between themselves, and no higher amplitude is possible.
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.
Can a sperm whale kill you with sound?

How far can humpback whale call be heard?
10,000 miles
How loud are sperm whales?
The sperm whale uses echolocation and vocalization as loud as 230 decibels (re 1 µPa m) underwater. It has the largest brain on Earth, more than five times heavier than a human’s.
How far away can you hear a blue whale’s heartbeat?
2 MILES AWAY
What is the biggest heart in the world?
The blue whale (Balaenoptera musculus) has the largest heart of any living creature.
