What is the loudest animal in the world?
Blue whalesThe blue whale is the loudest mammal of them all, with vocalizations that reach 188 decibels. Blue whales don’t have songs as complex as those of humpback whales, but their low-frequency “pulses”—some below the range of human hearing—have been recorded more than 500 miles (805 kilometers) away.
Can sperm whale sound kill a human?
In air, the sperm whale would still be extremely loud, but significantly less so — 174 decibels. That’s roughly equivalent to the decibel levels measured at the closest barometer, 100 miles away from the Krakatoa eruption, and is loud enough to rupture people’s ear drums.

What is the loudest sound on earth?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
What is the 3dB rule?
3dB rule and maximum exposure to noise To put it in context, a worker exposed to a continuous sound intensity level of 83dB(A) for one hour would be exposed to the same amount as someone exposed to an 80dB(A) level for two hours.
What is the loudest shrimp?

Why is 194 dB the loudest sound possible?
The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).

What frequency can humans hear by age?
Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it’s the upper frequencies we lose first. So by the time we hit middle-age, we can expect to hear up to around 14,000Hz.
