>>101852421Dr. Sivana is wrong in that most loud sounds run a few hundred of a few thousand decibels. The decibel system is a logarithmic scale, so the difference between 10 and 20 decibels is not the same as the difference between 20 and 30 decibels.
A running kitchen blender is somewhere around 70 decibels. Most gunshots are somewhere between 130 and 170 decibels, depending on the caliber. The Tunguska incident is estimated to have been between 300 and 315 decibels.
A million decibels...I'm not a scientist and I don't know the math to figure this out, but it would easily annihilate the planet. The sound itself probably wouldn't get far through the near-total vacuum of space, but the sheer heat it would produce would probably exceed that of any star over the same time period.
