Why is 194 dB the loudest sound possible?

A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves. You can go louder than 194 dB, but that's not technically a “sound” anymore.

How loud is the sun?

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.

How loud is a supernova?

If we suppose that the same fraction of a supernova's energy is converted to sound, and a supernova releases 1044 joules, That means that about 1044/(840 billion) = 1032 Joules of sound energy, thirty-two orders of magnitude greater than 120 dB, or about 440 decibels.

How loud is a plane taking off?

A study of noise on Airbus A321 aircraft reported levels of 60-65 decibels (dBA) before takeoff; 80-85 dBA during flight; and 75-80 dBA during landing. The outside of aircraft engines (around 140 dB at takeoff) and conditions on other aircraft may have higher or lower noise levels.

Is the universe noisy?

Einstein's theory of spacetime tells us that the real universe is not silent, but is actually alive with vibrating energy. Space and time carry a cacophony of vibrations with textures and timbres as rich and varied as the din of sounds in a tropical rain forest or the finale of a Wagner opera.
