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 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.
S1 makes a "lub" sound. It is the first heart sound in a normal rhythm. The sound is produced when the AV valves close.

The clicking sound of a sperm whale, is the loudest sound known of any animal on earth. At approximately 230 decibels, it can be heard for many miles underwater.
If you want the largest sound made by an animal that animal is the Blue Whale.
The blue whale is the loudest living animal on Earth at present. It can create sound waves through mating calls that go up to 188 decibels.
Howler Monkey (: :PLlions because a lion's roar can be heard from up to 6 miles away.
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.
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 1st heart sound, S1 (lub), marks the beginning of systole (end of systole). Related to the closure of the mitral and tricuspid valves. Loudest at the apex.
