How much is 1100 dB?
1100 dB = 10^98 joules. 10^98 J of energy > 4 x 10^69 J of the universe’s energy. Due to Einstein’s law of energy and mass, 10 ^ 98 J = 1.118 x 10^80 kg of mass. With a mass of that much, the radius of the event horizon = 1.747 x 10^37 light years.
Can a sound be so loud it kills you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

How many decibels would destroy the universe?
It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4×1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.
How many dB is a nuclear bomb?
280 dB+Nuclear bomb – Explosion A nuclear bomb explosion has been reported to be 240 to 280 dB+. A sound level meter set 250 feet away from test sites peaked at 210 decibels. At the source, the level is reported to be from 240 to 280 dB+.

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).
