Underwater Animals Are So Loud, They'd Damage Our Hearing

We often think of the ocean as a pretty serene, lovely place to relax. But it turns out there's quite a racket going on under the waves, and some of the culprits are not the animals you'd expect!

    Correction: In this episode, we make comparisons between underwater animal sounds and familiar sounds on land; however, the decibel scale starts in different places on water and on land, so these underwater sound aren't /quite/ as loud as they seem. For instance, if our ears worked perfectly underwater, a toadfish would only be as loud as a chainsaw (105db) not a jet taking off (130db). Thank you to Dr. Andrew Pyzdek for pointing that out!

    I don't get it. So is underwater sound decibels different from land air decibels? If 220 decibels on air we can hear it. But 220 decibels in water we cannot hear it because our bodies are not adapted to hearing through water. Maybe I'm overthinking.. I totally co fused myself in what I'm trying to ask.

    Just to point out that the comparison to human tolerance on basis of decibel (DB) is wrong. Underwater sound pressure, though also expressed in DB, which is a dimensionless measure in comparison with an agreed-upon reference level, uses a very different reference level from that used to define decibel when measuring sound pressure in air.

    This might be a stupid question but Ill ask it anyways. How can they be such high decibels? How can a small fish be "louder than a jet taking off"? I mean, if that was possible wouldnt diving into the ocean near these things blow your ears out? Im obviously missing some information about how this all works. Would love if someone could enlighten me!

    The water-air volume comparisons made in the video were quite misguided, because people use two different scales to measure amplitudes of sound in water and in air. The one in air has the 0dB reference at 20 uPa of pressure, while in water the 0dB is at 1uPa. Also same levels of pressure waves in air and water equate to different powers because of the different density and speed of sound. Taking all of this into account, to get a sound with the same level of energy measured with the dB scale commonly used in air you have to subtract ~ 61dB from the scale used in water - that means dividing by about one million the actual power of the wave!

    I always remember floating on my back in a certain murky salt water lake as kid and I could hear the clickety clack from crustaceans or shellfish at the bottom. I know there are small crabs and shellfish in the lake and at most it is just over 2 metres deep. Scariest part about swimming in there, even though it's allowed is that it's so close to the harbour where saltwater crocs are caught all the time and I once heard a baby or juvenile croc calling there at night so I know they go there. Sometime humans are just too loud and caught up in our own affairs so don't hear the sounds of nature. Shhh! I'm Aquaman...

    You have this all wrong. Because water is ~3600x as acoustically conductive as air, you need to subtract ~60db from the water db to get the equivalent air db. Most of what you're talking about is many orders of magnitude less loud than you're saying it is. None of it could damage your hearing unless it's well over 180db in water terms.

    This makes me wonder that if humans ever met extraterrestrial life, and it was also happened to be adapted to Earth like conditions, but its communication was done so loud it caused our ears to bleed. They could be really friendly and ask for the alien version of a hug and accidentally fracture the skulls of everybody within a 100 m radius. I mean it's highly improbable that any extraterrestrial life would be similar to us, they probably wouldn't even use the same frequencies that we do to communicate and that's presuming they even use sound waves, they could communicate through light, smell or something we haven't even thought of yet.
