The loudest sound ever recorded is believed to be the eruption of the Krakatoa volcano in 1883. The sound was heard up to 3,000 miles away and ruptured eardrums of sailors 40 miles away. It is estimated to have reached 180 to 190 decibels.

The loudest noise or sound is The Bloop because in 1997, U.S. NOAA heard a sound that is never been heard of that is also the loudest sound ever. The sound can cause from more than 5,000 km away from it's source. If it is an animal, it is louder and bigger than the loudest animal and the biggest animal in Earth.
The loudest thunder ever recorded was in Oklahoma in 2003, reaching 200 decibels.
The loudest sound of a volcanic eruption was heard during the 1883 eruption of Krakatoa in Indonesia. The sound was heard over 3,000 miles away and is considered one of the loudest sounds in recorded history.
194 dB (decibels) is the loudest sound on Earth ever. Some people say that the eruption of Krakatoa in 1883 was the loudest sound ever, being heard at 5,000 kilometers away! That eruption was around 180 dB!

An ex-wife ... lol Sorry, just couldn't resist ... ! _____________ Of the various natural things that can occur on earth without extra-terrestrial involvement, the loudest thing perhaps is the eruption of the caldera of a mega-volcano, or the eruption of a very large cone-producing volcano. Maybe louder still would be a collision with a very large comet or other body. I wouldn't like to be around in either case. Considering non-cataclysmic events, my guess would be: either the world's winds combined, or the world's surface water. If we could collect and concentrate the sound produced by either of these things, the loudness would be unexpected and phenomenal.
The loudest recorded earthquake occurred in Japan in March of 2011. The Pacific Marine Environmental Laboratory and Oregon State University stated it was the loudest underwater sound ever recorded.

According to my knowledge it is a whale it can produce 185 decibels of sound
The Krakatoa sound, recorded in 1883, was significant because it was one of the loudest sounds ever heard in recorded history. The eruption of the Krakatoa volcano caused a massive explosion that was heard over 3,000 miles away and had far-reaching effects on the environment and climate.
