How loud is a supernova?
If, hypothetically, there were air filling the universe, then suddenly things would get very loud.
Forget the terrifying concept of the sound of a supernova—just the dumb sun sitting there hanging out would ring in at an astounding 290 dB..
What does 0 decibels sound like?
86 dB is a loud sound but not dangerous—provided that exposure is brief. Remember that decibels measure a ratio. 0 dB occurs when you take the log of a ratio of 1 (log 1 = 0). So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level.
What does 1100 dB sound like?
A 1100 decibel sound would require so much air/matter and the compression would be so intense that all that mass would be compressed into a super massive black hole. Because decibels is a logarithmic scale. 100 decibels is a loud noise. 1100 db is 10 99 times more powerful than a loud noise.
What’s the loudest sound in the universe?
Going by this 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.
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.
How much is 1100 decibels?
1100 decibels is preposterous. 20 db is ten times as loud as 10 db. To the Human ear, it sounds about twice as loud.
Is there a limit to how loud a sound can be made?
Yes – there is a sound pressure limit for undistorted sound. … It depends on the environmental pressure, but there is a theoretical limit to loudness which you can find here. The limit is basically equal to the pressure.
What happens if you make a sound louder than 1100 dB?
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.
Why is 194 dB 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. … Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.
What’s 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.
What is the 3dB rule?
3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). … It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.
Is 70 dB 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.
Can you make a black hole with sound?
But physicists have also been developing ‘black holes’ for sound. They do this by coaxing a material to move faster than the speed of sound in that medium, so that sound waves travelling within it cannot keep up, like fish swimming in a fast-moving stream.
Can humans create a black hole?
“With about as much confidence as we can say anything in science, this is completely impossible.” To start with, theoretical physicist Stephen Hawking calculated all black holes should lose mass over time, giving it off as so-called Hawking radiation.
