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.

Which is the loudest thing in universe?

In the "known" universe, discounting the nature of sound (in that it requires a medium to propagate), the big bang was probably the "loudest".

What is the loudest sound possible?

Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. 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).

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 in decibels?

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. 3. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.

What is the LOUDEST Sound Ever Heard?



How loud is a 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. Fun fact!

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.

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.

How noisy is the Sun?

The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun's surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

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).

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!

What can produce 194 decibels?

A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level and 0 degrees C. Thus, the sound waves are creating vacuums between themselves, and no higher amplitude is possible.

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.

Is the universe silent?

Einstein's theory of spacetime tells us that the real universe is not silent, but is actually alive with vibrating energy. Space and time carry a cacophony of vibrations with textures and timbres as rich and varied as the din of sounds in a tropical rain forest or the finale of a Wagner opera.

Can sonic waves hurt you?

Yes, it can! Sound can kill you in multiple ways. If we're talking about sounds within the human hearing frequency range (between 20 and 20,000 Hz), high-intensity sounds above 150 decibels can burst your eardrums, while sounds above 185 dB can impact your inner organs and cause death.

How loud is the moon?

However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.

Do black holes make sound?

Now, humans can hear the sound of the black hole forever. Since 2003, the Perseus Galaxy has been known to have a noise-making black hole at its centre. At the time of discovery of this black hole, scientists had observed it for 53 hours.

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 Krakatoa?

The pressure wave generated by the colossal third explosion radiated out from Krakatoa at 1,086 km/h (675 mph). The eruption is estimated to have reached 310 dB, loud enough to be heard 5,000 kilometres (3,100 mi) away.

What causes a Hypernova?

A hypernova (sometimes called a collapsar) is a very energetic supernova thought to result from an extreme core-collapse scenario. In this case, a massive star (>30 solar masses) collapses to form a rotating black hole emitting twin energetic jets and surrounded by an accretion disk.

Can you hear a star explode in space?

NASA's new project turns up the volume on space's most extreme phenomena. In space, nobody can hear you scream — or explode, or collapse, or slowly collide with a neighboring galaxy.

Why was Krakatoa so loud?

In general, sounds are caused not by the end of the world but by fluctuations in air pressure. A barometer at the Batavia gasworks (100 miles away from Krakatoa) registered the ensuing spike in pressure at over 2.5 inches of mercury. That converts to over 172 decibels of sound pressure, an unimaginably loud noise.
