What animal can kill a whale?
The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”.
They have been known to work in groups to attack blue whales.
However, there are very few reports of orcas actually killing blue whales..
How many decibels does it take to kill a human?
The pain threshold for humans is 120-130 Decibels. Any sound above 85 dB can cause hearing loss, and the loss is related both to the power of the sound as well as the length of exposure.
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.
Can frequencies kill viruses?
“If the shell can be compromised [by mechanical vibrations], the virus can be inactivated.” Recent experimental evidence has shown that laser pulses tuned to the right frequency can kill certain viruses. However, locating these so-called resonant frequencies is a bit of trial and error.
Can a human survive in a whale?
You cannot be swallowed whole by any whale, as there is no whale whose throat is large enough to pass an average human into its stomach.
Has a whale ever swallowed a person?
The only whale that would likely be capable of swallowing a human would be a toothed whale, the sperm whale, which eats prey such as giant squid. A sperm whale did ram and sink the whale ship Essex in 1820, but there are no reliable reports of a sperm whale ever eating a human.
How much dB is a gunshot?
How loud is a gunshot? Decibel levels for firearms average between 140 and 165 dB.
Is 70 dB safe?
Recent statements published by government agencies indicate that 70 decibels is the only safe standard to protect hearing for the public. … And because the decibel scale is logarithmic, 85 dB is not 21% as loud as 70 dB, as might be commonly thought, but 1500% or 15 times as loud.
What is the loudest sound in the known universe?
The Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so astonishingly loud, that it’s inching up against the limits of what we mean by “sound.”
How many decibels does it take to destroy the universe?
Absent magical amulets or alliances with a powerful alien race, how could you pull it off? It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4×1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.
Can sound kill bacteria?
“Sonication is an alternative technology that uses ultrasound waves of frequency 20,000 hertz or greater to kill bacteria in food.” He said a high frequency sound wave’s energy (vibration) is capable of shaking apart bacterial cells like an opera singer shattering wine glasses.
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 is the loudest place on earth?
KrakatoaAt that very moment, the Indonesian volcanic island of Krakatoa was blowing itself to bits 2,233 miles away. Scientists think this is probably the loudest sound humans have ever accurately measured.
How loud is a supernova?
If, hypothetically, there were air filling the universe, then suddenly things would get very loud. Forget the terrifying concept of the sound of a supernova—just the dumb sun sitting there hanging out would ring in at an astounding 290 dB.
What frequency can kill you?
Sounds around 19 hz match the resonant frequency of the human eyeball, with reports of apparitions as detailed by the Coventry Telegraph newspaper. The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
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.
How many decibels is too loud?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
Can a sound be loud enough to 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. … The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you.
