Wait a minute, so you want all of us to die for these whales and shit?

@@GhilleGhille no he does not mean that he wants us to share with animals

@@GhilleGhille what does that have to do with dying?

Harsh reality is only a very few cares for the nature and rest others only watches and show grief and sometime they don't have time to show grief

I doubt the sound stressed you out, its the fucking wierd ass drawings they have to represent them. The whole video is basically saying animals are having a hard time communicating like they used to do as a result of human activity. thats it. the sounds themselves arnt killing animals and the ones that do are extremely close like when dolphins get injured or die when they get to close to a submarine conducting active sonar. it disturbs the ecosystem for sure but it's not affecting it enough to warrant taking resources we're putting into other means of reducing our footprint.

@@gamerx112so you’re cool if we just setup some sonar pulsing devices outside your house? They will go off regularly, daily, frequently. But don’t worry, it’s not a big enough problem to worry about. It’s no big deal.

@@gamerx112 yea no bruvvy, you pick and choose your battles, unfortunately no one will agreee with you so please dont try making another point out of it

Based on what?

@@tomtrenter3208 Military active sonar is extremely loud, loud enough to kill directly or cause injury that will result in death,

@@tomservo5007 have you measured source levels and frequecies at various ranges and depths to quantify your statement?

@@tomtrenter3208 are you questioning the fact that sonar can kill?

@@tomservo5007 close in maybe depending on mode, freq.., pulse length, to name a few. Sound propagation and attenuation, plus how you are from the transmitter affects the levels you receive. I do question blanket statements about active sonar killing everything in the ocean no matter how far away.

Sums up that people are more interested in clowns and retards rather than education and knowledge

Looks like the scum of the earth just plan of killing everything.

Nah

No, just you

@@baguette574 DUDE THIS IS SERIOUS DONT BEHAVE LIKE A DUMBASS WHO LIKES ROASTING

I'd like to see your source of info and what time of ship you are referring to because as a US Navy sonar technician, I can tell you that we still use sonar for detecting tracking and classifying. If we didn't use sonar anymore, I would be out of a job. I also invite you and anyone else to learn the physics of sound in water. Cause the dB level is not constant for the entire transmission of active sonar but is subject to propagation loss, absorption, and other factors.

​@@amandawoodward5596 I don't think there are very many folks who take the time to try and understand some of the basic physics of underwater sound and maybe the difference between active and passive sonar.

@@tomtrenter3208im very interested in sonars and sound, could you enlighten me and give me some good reads to dig deeper?

Thank you for your answer and your good thoughts. Surface piercing drives like Arneson are the quietest of the boat propulsion systems. Orcas seem not to mind these much. But turning your sonar off when not needed is also a huge help, as it can be very disturbing to mid- or high-frequency sensitive whales and dolphins. Choosing a sonar that is over 200 kHz is also preferable, but that may not give you enough penetration. Diesel engines with low rpms moving slowly don’t seem to be as disturbing to many whales as others, but are still somewhat noisy. Speed makes a large difference, with slower speeds almost always producing less noise.

Well, cargoship propellers are insanely loud and sound much worse than in the video. Sonar is also incredibly uncomfortable to listen to, and MUCH worse than in this video. The airguns do sound exactly like explosions, but worse. They are loud enough to penetrate through kilometres of rock. That's significantly louder than a rocket taking off. Literally everything you wrote in your comment is just wrong. Which leads me to ask this question: why would you write it? I agree that they should have exchanged the weak little sonar ping in the video for the real thing, which sounds horrible. It would have made it more impactful. But the airguns are spot on, and the propeller here isn't as bad as the real thing either.

@@michaelcaplin8969 Actually, Cargoship propellers aren't even that noisy. They emit a rather slow and rhythmic "sloshing" that is very distinct, but hardly "insanely loud". Now, small boat propellers or even outboarders are an entirely different story, as those are actually extremely loud thanks to their high rpm. Sonar is indeed very uncomfortable to hear, given it's high frequency and incredible volume. In fact it is so loud that it can kill people (divers) if they get too close, which turns military-grade active sonar into a very useful deterrent against enemy divers trying to sabotage your ship. My point with the seismic airgun wasn't so much addressing the intensity of the sound, but rather the filesample used to represent it here. You can clearly make out that the sound from the video is a shockwave traveling through air, most likely coming from an actual explosive going off. Due to their artificial nature (and their actual purpose), seismic airguns create a repeatable (less chaotic) pulse which sounds more like "thumping". Jive Turkey has made a very good analysis of an airgun sound sample, you should check that out if you want to hear the actual noise. Of course it's recorded from a large distance but you should be able to make out the difference in tone. As to why I made the comment in the first place, it was to point out things that bothered me personally while offering alternatives to improve the content. You may disagree with me, but thats what comments are ultimately for.

Agreed. I'm a sonar tech and have listened to merchant props and they just sound like one slapping water usually. And the sonar the depicted here was a poor representation. I hate stuff like this because it tells people is killing marine mammals while not actually talking about the physics of the sound in water and why this is happening nor do they address the measures we take in order to protect marine life. But they prefer painting the navy as the bad guy and anyone else who puts sound in water. Anyone who buys anything imported can blame themselves also. Hell part of mapping the ocean requires sonar.

​@@amandawoodward5596I don't know, the several videos of divers hearing military sonar pings reverberating across the sea floor sound pretty dang loud, and I know it's a lot more intense in person.

I wish it was, but this is something rlly serious

The hundreds of videos where divers are videoing when hearing a sonar ping say differently. It's loud enough to damage hearing and internal organs.
