How loud is a bullet?

Depending on the caliber of the firearm, most gunshots will register around 150-170 dB. At these levels, hearing damage can occur quickly. It’s also worth pointing out the proximity to our ears when shooting. Shouldering up against a shotgun or rifle places these ultra-loud noises very close to our ears.

Does the sun make noise?

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.

You can’t add them. You have to add the logarithm. so if 1 atomic bomb is 250 db, 5 atomic bombs exploding simultaneously is 250 + 10*log(5) = 257 dB. so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right.

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.
