Well your voice is the loudest thing you can use, and "ooo"s and "ahh"s are two of the easiest sounds you can get really loud by yelling.
Someone posted on FB that "The low frequency call of the Humpback Whale is the loudest noise made by a living creature, and can be heard from 500 miles away." I want to know if that was measured strictly underwater or if this is in fact the loudest noise made by a living creature...
If you want the largest sound made by an animal that animal is the Blue Whale.
The world's loudest man-made noise was the detonation of the Tsar Bomba, a Soviet hydrogen bomb tested in 1961. It produced a sound level estimated at around 210 decibels, which is beyond the threshold of pain and can cause immediate and permanent hearing damage.
Though Adelina Patti was an excellent 19th century opera singer, the low frequency call of the humpback whale is the loudest noise made by a living creature, able to be heard up to 500 miles away.
I believe the Saturn V moon rocket was the loudest man made sound.
probably me!
At a very close distance to the spider you hear the loudest sound.
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.
An atom bomb.
