CAN 1100 dB create a black hole
With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that.
Decibels are a logarithmic unit.
That means 20 decibels isn’t 2 times more powerful than 10 decibels, it’s 10 times more powerful..
Is 50 dB loud for a fan
40 dBA is a normal office noise level. 50 dBA of constant noise will induce fatigue. You will be quick to notice that using more than one fan, each smaller but each running at slower speeds results in a much quieter, less-maddening experience. The faster the fan the bigger the noise.

What is an acceptable dB noise level
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
How loud can a human yell
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.

Why is 194 dB the loudest sound possible
The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).

Is 50 dB too 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.
How loud is too loud for Sound Machine
Canadian and U.S. occupational health and safety authorities have recommended a workplace limit of 85 decibels over eight hours for adults. Three of the infant sleep machines in this study had outputs greater than 85 decibels, which exceeds that recommendation.
