What is the loudest sound on earth?
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..
Can sperm whale sound kill a human?
In air, the sperm whale would still be extremely loud, but significantly less so — 174 decibels. That’s roughly equivalent to the decibel levels measured at the closest barometer, 100 miles away from the Krakatoa eruption, and is loud enough to rupture people’s ear drums.
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.
Why do ears ring in silence?
But it can also be the result of a number of health conditions, such as noise-induced hearing loss; ear and sinus infections; diseases of the heart or blood vessels; Meniere’s disease, brain tumors, hormonal changes in women, thyroid abnormalities. “Tinnitus is sometimes the first sign of hearing loss in older people.
What sound can 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 sound levels are dangerous?
Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.
What causes sound?
Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.
Why is silence so loud?
The brain creates noise to fill the silence, and we hear this as tinnitus. Perhaps only someone with profound deafness can achieve this level of silence, so paradoxically loud.
Is white noise harmful?
The answer again, is YES. White noise machines benefit a baby by promoting sleep. However, it’s important to keep noise at a safe level for a baby and adults. If white noise machines produce sound above safe decibel levels, then they can be harmful.
How loud is 140 decibels?

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.
Why is whale vomit used in perfume?
Some sperm whales produce ambergris — a clump of squid beaks and fatty secretions that scientists believe exits through the whales’ bowels. Some high-end perfumes use ambergris for a chemical it contains called ambrien, which suspends smells in the air, and for its own unique scent.
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’s the loudest animal in the world?
Blue whalesThe blue whale is the loudest mammal of them all, with vocalizations that reach 188 decibels. Blue whales don’t have songs as complex as those of humpback whales, but their low-frequency “pulses”—some below the range of human hearing—have been recorded more than 500 miles (805 kilometers) away.
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.
What is the quietest place on Earth?
Orfield LaboratoriesThe quietest place on earth, an anechoic chamber at Orfield Laboratories in Minnesota, is so quiet that the longest anybody has been able to bear it is 45 minutes. Inside the room it’s silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA.
Can frequency 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.
