Unknown Extremely loud sound?

[Biotech Diver]

There is a YouTube video of divers experiencing a sonar ping, and nothing like the movies. It’s a long very intense high pitch sound, I’ll see if I can find it.

Here it is

Yes the movies illustrate the effect at the point of origin, the Doppler it’s more like what these guys heard as the target but this doesn’t fit MB’s description but I look forward to his response.

Wow, no wonder they say it confuses whales.

Thanks for all the replies. Definitely not dynamite fishing, I was diving in NZ in a marine reserve. A sonar ping would have been interesting, but it didn't sound like the video. NZ has a lot of volcanic activity, but not in the area I was diving. It was loud enough to make me instinctively "duck" and grab my pony regulator!

There are a lot of different sonar pings, depending on what the purpose of the ping is.

I actually went diving today (more on that later). Something curious happened. Diving solo. Got down to about 16 metres and heard an almighty sound. It was like someone smacking a steel girder with a hammer right next to my ear. It was a clear sound, not muffled in the way that sound often is underwater. I've been round the block. Heard anchors dropping before. ****, I've had one nearly dropped on me! Heard boat crew bashing dive weights on the hull to get divers attention. I've heard ladders being dropped etc. Nothing compares to the clarity or volume of what I experienced today. I fully expected my next breath to be a mouth full of water because my first stage or tank valve had exploded, but nothing. Everything functioning normally. No ear trouble before or afterwards. Any thoughts?

could be anything really sound travel quiet long in the water it could be due to shore activity. i dive in the st-lawrence river in the thousands islands region sometimes freight ship are couple of hundred yard from me, you could not imagine the sound of the propreler.

I had one of these dropped near me by mistake, recalling divers in another area not knowing I was in the area, I thought my head was going to explode.

We would not do that to our Kiwi cousins.

This topic has me intrigued.

Not even for a bit of fun?

I think the sound was mechanical rather than biological or geological because it was so metallic in nature, but it sounded so close that I was convinced it was something going on with my first stage/tank valve. That turned out not to be the case. I wasn't too far away from the dive boat, so it could have emanated from there, but I've never heard anything like it before.

I know you were solo, but were there other divers from the boat? Anyone else hear it?
