With a certain sound level in decibels, the sound turns into a shock wave, I think it's not a bad method.I'm not sure about what you say, we don't have any coefficients about shock wave attenuation after all, I'll also add another method in there as well
I'm also not sure about the method itself. A year ago, there was an explosion dozens of kilometers from the city and it was heard in the city itself. Needless to say, it wasn't a nuclear bomb?
