What sound frequency is harmful to humans?
Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing.
However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them..
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 soundwaves kill viruses?
Normal cells should not be affected by the virus-killing lasers or sound waves because they have resonant frequencies much lower than those of viruses, Sankey said. Moreover, it is unlikely that viruses will develop resistance to mechanical shaking, as they do to drugs.
How loud is the sun?
around 100 decibelsDeForest pegs the sun’s din on Earth at around 100 decibels, a bit quieter than the speakers at a rock concert.
What’s the loudest thing in the universe?
The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away. This is hailed as the loudest noise ever – and reported in.
What is the loudest jet in the world?
XF-84HThe XF-84H was almost certainly the loudest aircraft ever built, earning the nickname “Thunderscreech” as well as the “Mighty Ear Banger”.
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 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 loud is a lion?
The lion has the loudest roar of all the big cats. It’s so loud it can reach 114 decibels (at a distance of around one metre) and can be heard from as far away as five miles.
Can whale sound kill you?
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 infrasound kill you?
At high volumes, infrasound can directly affect the human central nervous system, causing disorientation, anxiety, panic, bowel spasms, nausea, vomiting and eventually organ rupture or even death from prolonged exposure.
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.
Can a sperm whale kill a human with sound?
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.
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.
What is the loudest animal in the world?

Has a killer whale ever eaten a human?
Killer whales (or orcas) are powerful predators capable of killing leopard seals and great white sharks. They have also been recorded preying on usually terrestrial species such as moose swimming between islands. In the wild, there have been no fatal attacks on humans.
What is the loudest shrimp?
Tiger Pistol ShrimpNative to the sunny Mediterranean, the Tiger Pistol Shrimp is among the loudest of the animal kingdom. They can produce sounds louder than a gunshot, weighing in at 200dB! When on the hunt for its prey, a Tiger Pistol Shrimp has a large claw that produces jets of water, which creates an air bubble.
What animal has a loud scream?
foxesThe loudest and most prominent sound made by foxes is the scream or contact call, typically used by vixens, or females, when they are ready to breed in the late winter and spring, Harris told LiveScience. This “blood-curdling” call “sounds a bit like somebody being murdered,” he said.
