How loud would a supernova be?

A supernova would sound like 10 octillion two-megaton nuclear bombs exploding. A supernova, however, just might be the most brutal concert in the universe.

How many decibels would a supernova be?

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.

Are supernovae loud?

Sound itself can only be transmitted through a medium and so in space we cannot hear a supernova. However since a supernova is a giant explosion triggered by the final death throes of a massive star, if we could hear it, we would hear an incredibly loud blast.

How loud would the sun be if you could hear it?

The Sun is similar in that it belts out rhythmic bass thumps over its background hum when certain frequencies overlap with one another. If space were replaced with air and we could hear the Sun, it would be incredibly noisy – the output of the Sun is equivalent to 10 million keys, or notes, of a piano.

How many decibels is a nuke?

Nuclear bomb – Explosion

A nuclear bomb explosion has been reported to be 240 to 280 dB+. A sound level meter set 250 feet away from test sites peaked at 210 decibels.

What Will It Look Like When Betelgeuse Goes Supernova? (4K UHD)

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.

What is the loudest sound in the universe?

The 1883 Krakatoa volcano eruption was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can't hear them.

What is louder than a supernova?

Yes, technically a fart on earth is louder than a supernova in space.

Can supernova be silent?

There's no sound in space, so you can't hear what a supernova sounds like.

How many decibels would destroy the universe?

Converting the energy of 1,100 decibels to mass yields 1.113x1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila! No more universe.

What does 100 decibels sound like?

A 100 dB sound like that of a power tool or a car horn is 100,000 times louder than a sound that is 50 decibels like an average suburban home or a quiet room.

What a black hole sounds like?

For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.

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 170 decibels?

120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.

What is 500 dB loud?

That means 500 decibels is 10²⁹ times more powerful than a nuclear bomb from 250 feet away. Supernovae are estimated to be around 10²⁸ megatons which means if the nukes mentioned above are 100 kilotons each, 500 decibels would be like listening to a supernova 250 feet in front of your face.

Can you hear explosion in space?

Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing. Exploding bombs, crashing asteroids, supernovas, and burning planets would similarly be silent in space.

What does a dying star sound like?

"You can think of it as hearing the star scream as it gets devoured, if you like," Jon Miller, a University of Michigan astronomer, said in a statement according to Space.com. The answer is surprisingly simple: It sounds like a D-sharp played with a synthesizer about 16 octaves lower than the middle of a keyboard.

Why is there no sound in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

How quiet is space?

Space isn't completely quiet — in fact, it's rather loud. Explore the anomalies that drown out all other noise. Sound doesn't travel in space. That's the knowledge most people have, however, it's not exactly true.

What is the quietest sound?

Typically, zero decibels sound pressure level (SPL) corresponds to 0.000002 Pascals — a measure of vibration or pressure waves that we really hear. So then, zero decibels is the smallest level of sound our ears can detect!

How loud is a scream in decibels?

The average decibel level of human speech is estimated between 55 and 65 decibels. A whisper is considered the lowest decibel level of human speech. A whisper is between 20-30 dB. On the other hand, a human scream can reach decibel levels between 80 and 125 dB.

Can we create 1100 dB?

so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right. Yes, that will create a blackhole.

Is 120db loud?

120 dB is a decibel level that describes extremely loud sounds. In fact, on a decibel chart, 120 dB marks the limit from which sounds become painful and very dangerous to the human ear.

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).
