What is the loudest word ever spoken?
No other than their teacher, who just happens to have the world’s loudest shout.
Miss Flanagan entered the record books back in 1994 with a thunderous rendition of ‘quiet!’ The shout clocked up an earth-shattering 121.7 decibels, setting a world record..
Why is 194 dB the loudest sound possible?
The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).
What sound frequency is harmful to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
What sound levels are dangerous?
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.
Is white noise harmful?
Too high a white noise level above safe decibels has the potential to cause harm, inflicting more damage on babies’ ears than if they had not been exposed at all. It’s important white noise stays at a safe volume for babies as well as adults. Keep sound levels to that of a soft shower – around 65 dB.
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.
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!
How loud is 92 decibels?
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.
How loud is an atomic bomb?
A nuclear bomb. Decibel meters set 250 feet away from test sites peaked at 210 decibels. The sound alone is enough to kill a human being, so if the bomb doesn’t kill you, the noise will.
CAN 1100 dB create a black hole?
With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn’t 2 times more powerful than 10 decibels, it’s 10 times more powerful.
How loud is a gunshot?
Firearms Are Loud A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss.
What is the loudest thing 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. It was so loud it was heard 3,000 miles (5,000 km) away.
What is the loudest thing in the universe?
As far as I’m aware, the Perseus galaxy cluster is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
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 a fart?
80 decibels“The different uses of ‘decibels’ in audio can get complicated,” Parker continues, but for simplicity’s sake, he says the average fart likely falls around 80 decibels of SPL, or sound pressure level.
