DeForest pegs the sun's din on Earth at around 100 decibels, a bit quieter than the speakers at a rock concert. That's during the day, of course. At night, as we turn away from the sun, the roar would fade.
Interestingly, the sound of the Sun is extremely loud. The sound that reaches the Earth from the Sun has been calculated to be around 100 decibels by the time it reaches the Earth as per data from American Academy of Audiology.
Today, we can hear the Sun's movement — all of its waves, loops and eruptions — with our own ears. This sound helps scientists study what can't be observed with the naked eye.
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.
Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet. In comparison, 120 decibels is a train horn about one metre away whereas 130 decibels is physical pain.
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.
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.
By DeForest's calculations, according to Astronomy, the Sun would sound like "10,000 Earths covered in police sirens, all screaming.” After traveling 92 million miles from the Sun to Earth, he believes, the sound would fall to about 100 decibels, like a constant rock concert.
85 – 100 decibels: For example, a hair dryer, blender, power lawn mower, forklift, or subway train. 100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail.
The sun would be absolutely deafening. This is because the sun, though it may look smooth and calm from Earth, is actually a maelstrom of superheated plasma. The nuclear reactions that power a star cause massive convection cells of superheated gas to rise and fall constantly across its surface.
If sound waves could travel through space, the sun burning would be as loud as a chainsaw. It's a good thing we can't hear space activity from Earth. If sound was able to travel, we'd hear the sun burning at 100 decibels, which is about the same volume as a chainsaw, jackhammer, or noisy subway.
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 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.
A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss.
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.
The Sun does indeed generate sound, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.
It turns out, not that loud at all. In decibels, it's a bit less than 120db.
Sound waves require a medium to travel from their source to our ears, like air or water. The vastness of space is almost empty, which means that even if we had space probes travelling through the cosmos, they wouldn't be able to capture audible frequencies with standard microphones.
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.
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 2004, Guinness World Records certified the anechoic chamber at Orfield Laboratories as the quietest place on Earth, with an ambient sound level of –9.4 decibels A-weighted.
