We often think of the ocean as a pretty serene & relaxing. But it turns out, it's shockingly loud under the waves, and some of the culprits are not the animals you'd expect! Join Hank Green for an oceanic episode of SciShow and learn all about it!

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!

Nice video! Please note that loudness of sound in air and water are measured slightly differently. The reference sound pressure level in water is 1 micro pascal and in air it is 20 micro pascal. Therefore 150 dB measured in water is approximately equivalent to 124 dB in air. So fish are not quite as loud as you make it to be, but they're still pretty darn loud!!
@victortitov1740

@@Energine1 I don't see the inconsistency. Sound is a physical, measurable force. Just because our ears can't hear it in certain environments doesn't mean its not there, measurable and equal in force to things on land. Water conducts sound better than air so there's not as much loss of force underwater but the rest of it is just a weird quirk of biology for various marine lifeforms.

I was thinking the same thing, all of those water to air volume equivalencies feel kind of hollow without any explanation to the actual function. We can't hear these things under water because we aren't equipped for it, but consider if the animal was taken out of the water, would it's sound function the same? If they are creating sound loud enough to kill a person, why doesn't it harm other sea creatures nearby? Learning how the sound is made is cool but without a mention of how other creatures receive those sounds or how sound travels through water vs air this just becomes a sensationalist "DID YOU KNOW!?" BuzzFeed style list. I guess I can make my ocean fearing friend uncomfortable with seahorse facts, that's something...

@dingo137
@dingo137 3 года назад
Yeah, the reference pressure is different and water has a very different acoustic impedance to air. In terms of intensity, the equivalent level in water is about 60 dB higher than for air. In terms of pressure, it's about 26 dB (that is, 126 dB in water corresponds to the same pressure amplitude as 100 dB in air).

@@andrewkolandjian9449 The number of decibels is 20 log (P/P0), where P0 is the reference pressure. P0 is usually defined to be 20 uPa in air and 1 uPa in water, so there's an extra factor of 20 inside the log. Since log(ab) = log(a) + log(b), that corresponds to an addition of 20 log(20) to the number of decibels, which is 26.0.

@victortitov1740
@victortitov1740 3 года назад
exactly. I hate audio people for creating this impossibly confusing system (more like, chaos) of measuring every possible and impossible quantity with decibels. For one, to compare sound intensity (i.e., energy density) between water decibels SPL and air decibels SPL, you should subtract approx 60 (thanks @dingo). suddenly, 115 db is just 55 db, which isn't loud at all. Then, it remains unknown, from what distance to the source the pressure was measured from, which is kinda important when you want to compare two sources.

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...

Imagine, at one point in time there was probably a whale out there who was the last of their kind and for their whole life they were chasing their own echo around the planet trying to find another member of their species.

I hear my cherry shrimp mating. I thought I was going crazy for a month hearing crap. Moved things around, changed pumps, messed with the stand.... turns out shrimp sound like underwater crickets.

My question is what reference pressure are you using for the dB levels? Generally speaking, in air, we use a reference of 20 micro Pascals, but in water, we use 1 micro Pascal. So one dB in air does not necessarily equal one dB in water.

Are they louder because of how sound works in water or, like if they could make these sounds in air they'd be this loud?

A form of the cavitation effect called the "water hammer" is what can make torpedo and mine attacks so dangerous to ships. You get the initial explosive blast of the warhead, which is a very sudden expansion of a large bubble in the water around the warhead and then that bubble slams back inward, creating the water hammer, since the side toward the ship only has damaged and weakened steel plate while the other side has an infinite amount of very solid water moving inward like the "Fist of God" to fill in the bubble. When the water hits its center, it will bounce back outward like a spring, though with less energy now and continue to do this again and again, rising upward due to the bubble floating in the heavy water. You thus get several water hammers up the side of the ship until the bubble reaches the surface and forms the huge vertical explosion seen in films. The initial blast and first hammer are by far the most damaging, but the others add to the damage and widen the hole in the ship. Deep underwater explosions underneath a ship can form bubbles that are large enough to break a ship's keel as the middle no longer has any water underneath it for a short while but the ends are still supported, folding the ship like a pocket knife closing. Cavitation also tears propellers apart as they can literally grind off the metal like a grinding wheel as the bubbles pop.

The Colorado river delta is pretty dried up. I'd be surprised to know even one drop gets there in this day and age. There are irrigation siphons off the Colorado on the western slope of Colorado to the extent we practically cut its flow in half... And it still has a thousand miles to go.

I can speak to personal experience, you can hear plenty of the sounds, if your in the water. You can't tell where it's from. As loud as they are the sources are usually small and distant. That's why we don't go deaf diving, assuming you equalized correctly.
