It's more powerful than your air horns

At first when I came to know about the noisiest animal i was taken aback.The world's noisiest land animals are the howling monkeys (ALOUATTA) of central and South America.

The males have an enlarged bony structure at the top of the windpipe, which enables the sound to reverberate, and the fearsome screams have been described as a cross between the bark of a dog and the bray of an ass increased a thousand fold.

Once in full voice they can be heard clearly up to 16 km/ 10 miles. Wow its interesting right. At first I thought that bird species were the noisiest but it became a wrong guess.
