The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.
but the loudest sound in the universe. is actually from the merger or collision. of 2 black holes. in what you're about to hear, scientists converted the gravitational waves. of 2 black holes, both 30 times the size of the sun, and converted them into sound waves.
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.
But what about the loudest sound ever heard? On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).
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……
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!
Hailey et al. 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.
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.
It's a ridiculously loud "sound". It's not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels.
No, because: 1) it's not possible to create sound beyond a 194 decibel limit. Anything louder is more accurately explosion, not sound.
Sound is measured in units called decibels. Sounds at or below 70 A-weighted decibels (dBA) are generally safe. Long or repeated exposure to sounds at or above 85 dBA can cause hearing loss.
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.
In perfect isolation, it would be impossible to hear a black hole. Hearing requires the presence of sound waves, and the presence of sound waves requires a substance to travel through. This also means that, again in perfect isolation, the process of two black holes merging releases no light and no sound.
Outer space is not completely empty; it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
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.
Today, we can hear the Sun's movement — all of its waves, loops and eruptions — with our own ears.
The viral audio, to be clear, is not a recording: it has been produced by 'sonifying' data taken from NASA's Chandra X-ray Observatory (another space telescope). The audio produced was originally 57 octaves below middle C, which meant the frequency had to be raised 'quadrillions' of times to be heard by human ears.
Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs. As for exploding heads, you can expect that from sounds above 240 dB. However, such high intensity sounds are very rare.
A one-time exposure to extreme loud sound or listening to loud sounds for a long time can cause hearing loss. Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die.
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.
Tsar Bomba (224dB)
The Hiroshima and Nagasaki bombs of 1945 destroyed cities in an instant – but the Tsar bomb was 3,300 times stronger than that and is considered the strongest sound every produced by mankind, with the most reliable figure suggesting it clocked at 224dB.
A study of noise on Airbus A321 aircraft reported levels of 60-65 decibels (dBA) before takeoff; 80-85 dBA during flight; and 75-80 dBA during landing. The outside of aircraft engines (around 140 dB at takeoff) and conditions on other aircraft may have higher or lower noise levels.
