Then the loud swishing noise of the screws going over your heads, the sonarman calling out in a hoarse whisper as he throws off the headset "Splashes!"

I served as a Sonar tech on two fast attack boats in the late 1990s and rarely did we ever use active ("ping") sonar for fear of detection. Instead we most often used "passive" sonar which is basically just listening for contacts and tracking them. Most sonar "pinging" you hear on RUclips is actually done by surface warships searching for submarines... ;)
Polish Sausage An unfathomably loud, high-pitched screeching sound that can literally liquify your organs but as mentioned above, it wouldn't make sense for a sub to just use active sonar for the hell of it.
Gregory Smith I’ve heard stories from the Cold War that submarines would tail each other silently and get within close range and use active sonar to make them shit their pants. I always assumed this was a common tactic even during peace time, thanks for the insight.
Pinging of that frequency in Silent Hunter usually means you're about to get depth charged. Run silent, run very deep, and hope he doesn't have an exact fix.
I always thought it would sound like a ping, but at sea on a warship when a submarine 'pings' you, it tends to sound like a long squeak with a rising pitch towards the end. I always used to hear it, poo my pants and then collapse with fear. During my service it was always the thing that scared me the most! A certain type of surface warship used to test theirs in close proximity to us also and it sounded almost the same as the submarine one.
Why the hell would a submarine ping you if you were on a warship? Submarines would easily be able to detect a noisy old warship using passive sonar, which is just using hydrophones to listen to your engine and propeller noises, and the cavitation your propellers would inevitably make. Besides, submarines see warships as their greatest threat. They sure as hell wouldn’t give their position away by pinging you. Hell, their active sonar detection range is shorter than their passive sonar detection range. That means that they’d have detected you with passive sonar long, long before they were in range to ping you. What gives? This doesn’t quite add up.
surface ships are targets. doesnt matter if its a usnavy ship, its still a target. the upsweep active you heard were your own ships depth finders. or another ships df if it were close enough to you. if there were any boats around while you were out to sea, they absolutely had you acquired on broadband and classified by demon and had a fire control solution on you many minutes before you even thought you could have had a possible detection.
Nothing like this on newer boats. More like a series of high pitches whistles of varying frequency. Whenever people ask about it, I always liken it to the sounds dolphins make underwater with greater range...kinda hard to describe.
That’s a speaker making stock sounds in the sub which is probably a floating museum now by the looks of that plexiglass panel off to the left side there.. 😑
Ben Sanspiro damn right, that’s probably a highly classified sound your hearing. I’m not sure why he was recording because he clearly didn’t have permission to do so, I also could be wrong. If the navy didn’t want this video on RUclips then they would have taken it down already so who knows?
Tis fairly obvious that this is a recording coming through speakers for visitors. You wouldn't operate a ww2 era sonar transducer just for the kicks of some visitors lol that's akin to 'lets let little timmy fire this blank howitzer'
This is the USS Pampanito, when they were restoring her they had the original crew helping out and my dad, as subsurface MM, worked with them to get the diesels running again. The boat is at 90% functional capacity and the WW2 vets who served on her 40 years prior wanted to take her around the port one last time. The Coast Guard denied them the pleasure, wouldn't even let them get towed around by a tug, citing it was a hazard. Dad said that little guardsman who denied the request got his ass chewed by an old sailor up one end and down the other. Why deny our nation's heros the chance to do that toward the end of their lives? It's not like they couldn't have arranged for them to do it safely.
At the decibel level of an active sonar ping it turns from a “sound” into more of a shockwave. Imagine swimming in a lake or a river, and seeing a speedboat pass maybe, 5 or 600 yards out with an engine that produces say.... 105 Db. Put your head underwater and you can hear it as if it’s 100 ft away. Now take 230 -235 decibels which is sonar...that’s unbelievably loud, and be 500 yards from that and...your insides are probably mashed potatoes from pressure.
This is what we came to achieve. The most secure prison in existence and it is one entered willingly. The whole experience of being a submariner is so eerie...
Now what's an incoming ping from this era like? When I play a modern sub sim, it soulds like this horrifying echoing screech at 3500 Hz that echoes onward for a good 10 seconds.
The first time i heard sonar coming from our ship i could not figure out where it was originating from, the whole forward section of the ship was resonating with a high frequency warbling. Omni
Lothar-Günther Buchheim (war correspondent on the U-96 in 1941) describes the sonar as "a bunch of small stones thrown against the hull". I wonder if the famous ping, we all know was established later, since the sonar was undergoing a strong development during WW2. Anybody having resources to clarify this?
Imagine its late at night, your on your dreaded late shift but you've been out at sea for so long that the time of day has lost meaning. It's dark, and the ship is currently conserving power by keeping the lights low. It's cramped, claustrophobic but quiet. Hopefully it'll be just as quiet as a night... Then you hear it, feel it. A sound from the deep. Ping... Ping... It's likely another warship using active sonar to try and find you. The entire ship quiets down, shutting off engines and power for a moment to try and avoid detection. The order to go silent was... Well, silent. You hold your breath as the sub quietly sits there, remaining still. Ping... Ping... You can only hope they don't hear you. (This was just an idea, I find submarines really fuckin cool- And scary! Scarily awesome! Ahaha- Nah but they do have a certain horror mood that really makes me appreciate them more)
Patrick EH I've already taken a college physics class and I've known about the inverse square law since high school. It at least harms fish within 20 feet of the speaker, although I haven't done calculations. I imagine for there to be stories of it harming dolphins it would have to be harmful farther away rather than closer because fish would probably try to escape it
Then why are you babbling on so stupidly? Fish move AWAY from subs and don't hand around close enough to be injured in ANY significant numbers. The microphones used to pick up the returns are SUPER sensitive. They can hear a small fish jumping from the water a LONG distance off. Get your brainectomy reversed.
Usually if you are in the water and you get pinged by a warship it sounds like a squeak rising in pitch then it stops and then less then a second after you hear another squeaks that sounds like the other half of the first one then it stops then you hear one last squeak that actually sounds more like a high piched ping
How loud is it on board? I know when newer subs go active with their sonar it can kill a person within a pretty big radius of the vessel, but I’ve always wondered about being in the interior.
It's the sound an Active Sonar Ping used to make. It's hard to find actual audio samples of this because the new ones are much easier to find and are called the same thing. You can find a different but long recording of an old active sonar ping on this site: maritime.org/sound/ Just ctrl+F "active sonar ping" and download the audio file if you're interested in hearing it. I found this recently also wondering what the thing the sound is emitted from looks like, but no luck yet.
unless this was recorded decades ago, like when the 41 for freedom boats (or other diesel boats) were around, then this is absolutely not authentic. Q5-E sonar suites dont even have an option to go active at this frequency. the classic "ping" everyone associates with navy boats is only used (very rarely, however) by civilian vessels. most active sonar freqs are above 20khz (humans high freq range is 20khz) and the ones that arent, like the depth finder & emergency active, are measured in milliseconds. they sound more like really fast clicks or blips.
@@koekie7003 the only active sonar the u. s. navy uses below 20khz is the depth finder, everything else is above it. eta - i know this for a fact as my rating in the navy was STS3/SS (sonar tech, submarines, 3rd class petty officer/qualified for warfare on submersible ships)
@@wilsoncrocker so most of active sonar is above 20kHz? dang I though most were from 1-10kHz I assume you won't be able to hear these then but still pick them up with your equipment?
@@koekie7003 bingo... doesnt matter if you can hear it, only matters if the transducers can detect it, the comps can process & analyze it, & the FTs can use it for a target control solution. the stacks have software that turn hf signals into a visual representation that we use to get range bearing rate etc...
This is in a restored WWII sub that's partially submerged at Battleship Cove. It might be a recording, but it's probably one of the sub's active sonar. There are many different sonar sounds, though.
Crazy Fox I’m lost as to what you’re saying. Not only is the submarine the source of the ping, but even if this was taken on another submarine listening to this one, they’d most certainly hear the loud and clear. Sound travels much more effectively underwater. In fact, most submarines refrain from pinging since it’s a tell tail-tale of their position
Local Tofu Delivery Driver that's a surface vessel detection device. That uses radio waves to detect SURFACE ships and aircraft. Underwater vessels and torpedos are detected with sonar. They also do their own detecting with their own sonar. That's how they "see". Radar doesn't work underwater.
I've seen some developmental sonar hardware, it was basically a big loudspeaker but with no cone, just the voice coil part, and of course rugged and waterproof. "Transducer". They can handle a lot of power b/c the water is denser and more rigid than the air, and also has much higher thermal conductivity. So you might have one big amplifier for one transducer, hundreds of watts each. There were also some smaller ones for high frequency, that I think were like piezoelectric. My impression was that the sonar is making a tremendous sound, which the operator of course doesn't hear. Probably killing fish. Anyway, they're listening for the echo, which is millions of times less power. I guess from the sonar's point of view, the WORLD is beeping or clicking or whatever, and you try to sift out some range and heading information out of all that as best you can.
that moment when you get a ping back :/
