A Supernova Explosion is very loud?

Answer 1

Loud is a relative term used in hearing depending on what object is doing the hearing and what frequency range. For example, what is loud to dogs would be silent to humans if the sound is outside of the human hearing bandwidth 100-20,000 Hz. Loud for humans would be generally described as passing the pain threshold of hearing.

Answer 2

That depends on you and your sensitivity. 120 dB is terribly loud. People who run sound for events (other than those where attendees generally both expect and want it to be loud, such as rock concerts) find that typically they begin getting complaints about it being "too loud" somewhere in the vicinity of 90 dB.

Answer 3

A jet engine, or a rifle being fired. It depends how far you are from the sound source. Scroll down to related links and look at "Sound pressure - Wikipedia".

Answer 4

No. Sounds requires a physical material to transfer its energy (like air), since supernova explosions take place in the vacuum of space, there is no way for sound to be transmitted.

Answer 5

It is 194pb a gun shot is 144

I believe it was the eruption of Krakatoa, Indonesia in 1883, with the explosions heard over 3500km or 2200mls away in Perth, Australia.

Answer 6

False, they are entirely silent.
