What is the loudest sound ever made by a human?

Frightening Context. The loudest sound ever created by humans, not by natural causes, was said to be the atomic bomb blasts over Nagasaki and Hiroshima. Those clocked in at around 250 decibels. NASA's highest recorded decibel reading was 204 and that was the first stage of the Saturn V rocket.

What sounds are 50 decibels?

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, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves. You can go louder than 194 dB, but that's not technically a “sound” anymore.

How loud is a rifle?

Firearms Are Loud

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.

Is 120db 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.

How loud is a nuke?

Listen to this. 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.

How loud is a black hole?

Apparently, a sound of 1,100 decibels would create so much energy, it would act as a immensely high quantity of mass. This would, in turn, create enough gravity to form an extremely large black hole! Larger, in fact, than our observable universe.

How loud is the sun?

One heliophysicist crunched the numbers and estimates the noise would be around 110 decibels, or about the same volume as speakers at a rock concert.

How loud is space?

Studies on a single space shuttle flight found temporary partial deafness in the crew. Inside the International Space Station (ISS) it is so loud that some fear for the astronauts' hearing. At its worst, the noise level in sleep stations was about the same as in a very noisy office (65 decibels).

Can sound destroy the universe?

It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4x1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.

What does a nuke smell like?

Other bombs smell like the materials which cause the explosion, e.g., napalm smells like gasoline and tnt smells like gun powder.

How loud is a supernova?

If we suppose that the same fraction of a supernova's energy is converted to sound, and a supernova releases 10⁴⁴ joules, That means that about 10⁴⁴/(840 billion) = 10³² Joules of sound energy, thirty-two orders of magnitude greater than 120 dB, or about 440 decibels.

Is Hiroshima still radioactive?

Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
