What was the farthest-travelled airborne sound in history?

I would risk to say a "Space shuttle lauch". It could up to 106dB(A) SPL at 6 kilometres. What this means
is that any normal person will automatically cover their ears - at such a
distance!


If we agree that "detonations or explosions " don't really count because you can make them as loud as you want, given enough explosives.

No, not a launch. Are you sure we can make an explosion as loud as we want? What if we used all the explosive in the world and it still wasn't as loud as we want? (Think Heavy Metal: it's never loud enough.) But no, it's not making an explosion as loud as we want. Because this already happened.

Must be a volcanic explosion, like Krakatoa or Santorini.The greatest in recorded history was when Tambora, in modern Indonesia, erupted in 1815.The blast was heard 1,000 km away.What's that in miles? Ah yes, it's 1,000 times about 5 furlongs divided by eight =c 625 miles.

Yes, it was Krakatoa. In 1883 it ejected more than 25 cubic kilometres of rock, ash, and pumice, and generated the loudest sound historically reported. It was distinctly heard in Perth, Australia approx. 1,930 miles (3,110 km) away, and as far away as the island of Rodrigues near Mauritius approx. 3,000 miles (5,000 km) away.

It has been claimed that it was the loudest sound ever heard by human beings but that's not at all likely . First of all, that was less than 200 years ago, and already it is getting ready to blow again. And humans have been around arguably from between 2.5 million years ago to 35,000 years ago. Okay, okay, to 6,012 years ago when some believe we were usshered in.

This question was asked years ago in Trivia. Since I can't find it, I have to assume that someone deleted it.

Some time after Krakatoa exploded, sounds of distant gunfire or thunder were reported in Texas.


"...when some believe we were usshered in."


Very good, Babs! In April, I believe he said. On a Friday. In the morning.

Thanx. Didn't think anyone would notice it!

By contrast, I heard Mt. St. Helens explode in 1980 while living in Seattle about 100 miles away. Nothing to write home about -- sounded like somebody slapped the side of my house with their hand. Now if Mt. Rainier ever erupts...

I wonder how loud Yellowstone will be when it erupts? I have a feeling that Everyone in Europe and Asia will hear it, assuming, of course, that there will be people in Europe and Asia whenever it does.
