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.
An artificial black hole produced using sound waves and a dielectric medium has been created in the lab, according to researchers with an international think tank featuring more than 30 Ph. D. research scientists from around the world.
In fact, the possibility of creating a black hole in a lab is a goal that scientists are actively pursuing—one that could allow researchers to answer many fundamental questions about quantum mechanics and the nature of gravity. A black hole typically forms when a star much more massive than our sun dies.
on edge of Black Hole. Space and time are intertwined, called space-time, and gravity has the ability to stretch space-time. Objects with a large mass will be able to stretch space-time to the point where our perception of it changes, known as time dilation.
' 'What this incredible temperature means is that mini black holes of tiny mass 'evaporate' into the far, far colder space around them almost infinitely fast. Their expected lifetime is around one octillionth of a nanosecond – so that they pop out of existence again almost as soon as they are created.

a sound greater than 1,100 decibels would unleash enough energy to act like an equivalent quantity of mass. Through Einstein's laws of relativity, this mass would create enough gravity enough to form a black hole. Shortly thereafter, everything in existence would disappear in a crush of sound.
Great Big Story visually recounted the singular natural event that caused the loudest sound in the world. This sound, measured at an incredible 310 decibels was made in 1883 by the eruption of Krakatoa, a volcano in the Sunda Strait of Indonesia.
At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.
Loud appliances such as a vacuum cleaner or power tools could exceed 80 dB. 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!
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.
The loudest fart ever recorded occurred on May 16, 1972 in Madeline, Texas by Alvin Meshits. The blast maintained a level of 194 decibels for one third of a second.” Then there's the Guiness Book of World Records……
After some calculations, he explained that the Sun would theoretically blare out a noise of around 100 decibels, almost as loud as standing next to a speaker at a rock concert or busy nightclub. That's pretty remarkable when you consider the Sun is 150 million kilometers (over 93,000,000 miles) away from us.
It turns out, not that loud at all. In decibels, it's a bit less than 120db.
Today, we can hear the Sun's movement — all of its waves, loops and eruptions — with our own ears.
The noise from the largest detonated atomic bomb, the RDS-202 Tsar Bomb, can be estimated at an incredible 224 dB.
The grenade is thrown and explodes after a roughly 1.5-second delay. The explosion of magnesium-based pyrotechnic chemicals causes a very bright flash and a loud sound (160−180 decibels), which can cause temporary blindness, temporary loss of hearing and loss of balance, as well as a sense of panic.
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.
A normal voice level is between 60-70 dB. A raised voice is between 65-75 dB. A very loud voice is between 75-85 dB. A shouting voice is above 85 dB.
Sounds above 150 dB have the potential of causing life-threatening issues. Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs.
Steve Orfield explained: “what the chamber tends to do is it tends to scare people because when you get in the chamber, everything gets tremendously quiet. You feel like there's pressure on your ears – but it's actually pressure moving away from your ears.
Wish you could sit in the quietest room just to get some peace and quiet? Be careful what you wish for; it may drive you crazy. The quietest place on earth is an anechoic chamber at Orfield Laboratories in Minnesota. The space is so quiet that the longest anybody has been able to bear it was an entire 45 minutes.
