Are humans louder then animals

Answer 1

Depends on if said humans are using any type of Enhancer, and what Animal your refering to.

If you exclude humans using amped music, then the lowly little "water boatman," or Micronecta scholtzi is considered the loudest creature on earth. If you compare, pound for pound (or gram for gram in this case), the water boatman is the loudest when you consider size ratio.

Granted it's an insect, not an animal, but we'll ignore that because of the incredible sound it can make. It can reach 99.2 decibels when it "sings". This is about as loud as a diesel truck barreling down a road. Thankfully, it's underwater so humans are spared the full blast of its singing.

If you are looking for the loudest, regardless of size ratio, then you need to look at the Blue Whale, which can sing at an ear deafening 188 decibels. A bull elephant can roar at a piercing 117 decibels. Compare the tiny little boatman, at 50 micrometres to these behemoths and then you get an idea of how truly astounding it is to have 99 decibels come out of something smaller than an elephant toe nail.
