The 1883 explosive eruption of Krakatoa volcano made the loudest sound in history

The final fourth explosion of the 1883 eruption generated a sound estimated to have a volume of 310 dB [1]. If something is ten times louder than something it is 10 dB greater on the logarithmic scale. The Krakatoa explosion was so loud that it ruptured sailors' eardrums 64 km away and it could be heard clearly 5000 km away.
In comparison, a fighter jet takeoff about 25 metres away equals about 150 dB (enough to cause eardrums to rupture). A difference of 160 dB translates a difference of 16 orders of magnitude, that is a number with 16 zeros in it.

Hi Markku. Then that is loud. To rupture an eardrum it has to be loud. 64 KM away then I would hate to be closer. Nice fact.

Anything as powerful as the final fourth explosion is hard to imagine. Four times less energy was released in the detonation of the most powerful nuclear bomb ever detonated, the Tsar Bomba (50 megaton yield).

With a force like that maybe within 10 km it would probably kill you. Be brain dead and deaf anyway. Don't know what the maximum noise a human can take. There won't be any volunteers.

Very interesting quote. Once reading about atomic bombs said that the strongest bomb, the bomb of the Tsar in addition to listening to thousands of kilometers, swept the clouds with an expansive sling that went around the globe three times. Now that I say, Finland must be very close to the site of the explosion, perhaps broke the windows of the house of your grandfather friend Markku. Jaja

Too far to break my grandparent's windows. :)
But the sound may have been heard in northern Finland.

That's sick, once I downloaded a sound meter app to measure the dB because I wanted to learn to whistle higher and a friend was teaching me and the maximum that managed to reach was 87 dB, the app classified it as equivalent to loud music, of course I tested with the cell phone 7 or maybe 10 cm from my face.

So, could any person or animal at that time be deaf? Imagine the animals that have a well-developed sense of hearing. example the bats, if that sound was so strong ..

Still not as loud as the microwave beeping at 3 am.
