The current shouting record has been held by Annalisa Wray since 1994. At the Citybus Challenge in Belfast, Northern Ireland, she ironically yelled the word "quiet" to a level of 121.7 dBA. That's almost as loud as a jet engine!
Miss Flanagan entered the record books back in 1994 with a thunderous rendition of 'quiet! ' The shout clocked up an earth-shattering 121.7 decibels, setting a world record.
Decibel levels:
A normal conversation – 60 dB. A noisy restaurant – 70 dB. An electric drill – 95 dB. Jill Drake, a teaching assistant who in 2000 won the Guinness World Record for the loudest individual's shout – 129 dB.
The Belfast primary school teacher bellowed her way into the world record books in 1994 with a thunderous bellow of the word (what else?) 'quiet! '. The shout clocked up an earth-shattering 121.7 decibels, setting a world record and potentially damaging the hearing of anyone within earshot.
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! You should also have found sound levels drop off quickly as you get farther from the source.
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.
Common Sources of Noise and Decibel Levels
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.
The loudest fart in the world was recorded at 118.1 decibels. It happened on May 11th, 1972 in Flint, Michigan by a man named Paul Hunn. The fart lasted for two minutes and forty-two seconds.

Quote by Stephen Hawking: “Quiet people have the loudest minds.”
The report revealed that the South Asian region which includes India, Pakistan, Bangladesh, Sri Lanka, and Nepal is the noisiest in the world with Latin America and Europe as the quietest regions.
If you've been to Japan, you're likely as astonished as I am to learn that the World Health Organization recently reported Japan to be the world's noisiest country. Chiara Terzuolo, Japan Today, writes: [T]he WHO recommends avoiding being exposed to noise over 53 decibels.
The WHO guidelines for night noise recommend less than 40 dB(A) of annual average (Lnight) outside of bedrooms to prevent adverse health effects from night noise.
The Danger Of Above 85 Decibels
Joshua Leeds, the president of BioAcoustic Research Inc., would say that anything above 85 decibels (dB) is too loud for dogs to hear as these sounds could cause hearing loss in dogs (source).
As a rule of thumb, babies should not be exposed to noise levels over 60 decibels. The noise level recommended for hospital nurseries is actually lower, at 50 dB. For reference, a quiet conversation is between 50 and 55 dB and an alarm clock is 80 dB.
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.
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.
Teacher Annalisa Flanagan from Comber has something to shout about after her sensational voice was re-entered into the Guinness Book of Records as the loudest in the world.
Bell Miners are heard more often than seen, their loud 'ping' contact calls incessantly ring out across the forest from morning to afternoon and are a characteristic sound of the Australian bush.
In general, women speak at a higher pitch—about an octave higher than men. An adult woman's average range is from 165 to 255 Hz, while a man's is 85 to 155 Hz (see sources). Men's voices are generally deeper because the surge of testosterone released during puberty causes their vocal cords to elongate and thicken.
