This was an incredibly challenging video to make. The challenge came with getting the Navy to agree to the interview in the first place, then successfully navigating the interview without it being shut down. In the end, everyone was super professional and it was a really fun topic to learn about! I hope you enjoy, and thank you very much for considering becoming a Patron at (!

One additional factor on sound "bending"...add distance. Over great distances, lower frequencies will overtake high it is possible to hear the "bass" notes first enen though the initial emmittance was the reverse of that. (former sonar tech on fast attack sub).

Can passive sonar be used for navigation. Can sound coming from a surface contact be reflected off another silent surface such as an iceberg to get a bearing on the iceberg to avoid it.

I haven't understood why they don't use the circular radar like graph to see the moving of contacts around them. The bearing graph with the contact angles in a straight li e seems so unnatural. Why do they prefer it?

Most Sonar tech is classified. What is really cool is physically seeing the sonar dome up close. The line only means possible contact. What it sounds like and classification is what could mean life or death. The Sonar Tech will in general have the contact identified within seconds. FYI: You are not going to use active sonar to tail a mysterious craft lol.

If you want to know a simple version that not classified but actually what deaf/hard of hearing/cochlear and blind individuals go through.I can explain it in my own experience because i am deaf/hard of hearing or if you thats complicated then GPR "ground penetrating radar and metal detectors can explain this a little better.

Matthew 24:45-51 (KJV) Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? Blessed is that servant, whom his lord when he cometh shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. But and if that evil servant shall say in his heart, My lord delayeth his coming; And shall begin to smite his fellowservants, and to eat and drink with the drunken; The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.

issue is though that the Best Depth calculations aren't exactly 'secret' either, and can be found online at the Federation of American Scientists or in a basic sonar physics manual if you've had to deal with underwater sonar at a program level you have to know it because it can interfer with depth sounding, but the calculations change based on depth Best Depth = 17SQRTLayer Depth if the depth is less then 60 meters else it's LD + 60m.

Really love your series - I was ET in Navy... officially trained Radar, Coms and microelectronics but worked on ASW training facility as staff for a while - helped sonar tech (that just swap boards) and operators repair many systems for our aging sonar systems - sure hope they have made improvements since then - I had to reverse engineer many HP systems to rebuild with modern components... anyhow - even old systems have a lot of classified intel - but what amazes me is how many sounds and profiles the USN has on just about everything that has ever been made known to man and how quickly they can identify just about everything on planet earth by acoustic signatures from ambient passive and active sources.
