SUMMARY

The discussion centers on the hypothetical sound produced by a supernova surrounded by an Earth-like atmosphere. It concludes that supernovae generate supersonic shockwaves that would create a sonic boom effect, significantly louder than typical explosions. The conversation also touches on the challenges of sound propagation over vast distances, suggesting that sound waves may lose energy before reaching an observer. Additionally, it references NASA's work in converting electromagnetic fields into sound, indicating a potential method for experiencing supernova sounds through alternative means.

PREREQUISITES
  • Understanding of sound wave propagation in different mediums
  • Basic knowledge of supernova mechanics and shockwave formation
  • Familiarity with the concept of sonic booms
  • Awareness of NASA's methods for converting electromagnetic data into sound
NEXT STEPS
  • Research the physics of sound wave propagation in various atmospheric conditions
  • Explore the mechanics of supernova explosions and their impact on surrounding environments
  • Learn about sonic boom phenomena and their characteristics
  • Investigate NASA's techniques for converting astronomical data into auditory experiences
USEFUL FOR

Astronomy enthusiasts, sound engineers, physicists, and anyone interested in the intersection of astrophysics and acoustics.

I obviously realize that sound requires a medium to go through. However, suppose that there was a supernova and it was magically surrounded by an atmosphere that has the same composition and density as Earth's atmosphere. Now, if you were far enough away so you didn't get wiped out, then what would it sound like? Would it sound like a regular explosion or something completely novel. Also, how would the sound change if the supernova formed a black hole? Thanks for your time.

I'm not sure the sound wave could actually propagate through a few dozen light years of atmosphere without losing all of its energy. You might not hear a thing.

Supernovae create supersonic shockwaves through the interstellar medium. These move much faster than the speed of sound, so they would hit you as a sonic boom on steroids.

Not exactly the same but NASA converted the electromagnetic fields of the planets into sound and it's pretty amazing () I'd imagine you could do a similar sort of thing with a supernova.
 
You don't need to do the same thing in supernovae. Supernovae are already large explosions that emit plent of pressure waves that are, by definition, sound. The only really question is how loud it would be given the low base pressures involved and where the observer is located.
