No need for loudspeaker-2

Coming to the second part of the blog of those animals boasting loud noises.

Even, the largest herbivores have the most high-pitched vocalizations. Elephants which are terrestrial giants are symbolic for their loud trumpets and also horrifying loud roars. These sounds are audible to other elephants standing at a distance of 2 km away. Even, their infra sound which is grumbling is known to travel far off distance.

Similarly, another terrestrial giant hippos are again louder with their grunts and bellows with the bellow of a bull hippopotamus being too loud to hear.

Loudest among them are two whales - the gigantic blue whale whose whistles are really loud out sounding a jet engine and can be heard by other whales of its kind. But, the loudest not only among the entire category of whales but of all animals is the sperm whale. These toothed cetaceans are the loudest with their clicks lasting from 15-30 seconds out sounding blue whale.

And, the Guinness world record holder for the noisiest land animal, the howler monkey is no exception. Their call resembling a threatening roar rather than a howl can be heard for miles away in the rain forests sounding around 128 db.




Other animals with loud noises include tiger pistol shrimp, Greater bulldog bat, American bullfrog ( loudest amphibian). 

So, the posts of this topic (1&2) tells us to shield our god given ears while listening to these animals.
