When you're standing at the pearly gates explaining to God how you died on the Titanic 111 years after it sank..
That's not quite correct. Sound waves propogate through water extremely well. Here's an example of a 55 gallon drum getting crushed by atmospheric pressure. You can hear quite a loud pop.
I thought dog was omniscient. How'd it not know?When you're standing at the pearly gates explaining to God how you died on the Titanic 111 years after it sank..
How does that drum in the video not being underwater affect what I said?I agree with your statement but that wasn't underwater. Sound waves definitely travel underwater. If you've ever been underwater and someone 20 feet away smashed rocks together underwater you know it.
Donnie is a scientist.I agree with your statement but that wasn't underwater. Sound waves definitely travel underwater. If you've ever been underwater and someone 20 feet away smashed rocks together underwater you know it.
Because Donnie was talking about sound waves underwater. I did say that I agree with your statement that sound waves propagate well underwater it's just the video doesn't demonstrate that because it's not done underwater.How does that drum in the video not being underwater affect what I said?
How are you guys so dumb as to not get an obvious joke ?Because Donnie was talking about sound waves underwater. I did say that I agree with your statement that sound waves propagate well underwater it's just the video doesn't demonstrate that because it's not done underwater.
Oh ok. The medium is different but the effect is the same.Because Donnie was talking about sound waves underwater. I did say that I agree with your statement that sound waves propagate well underwater it's just the video doesn't demonstrate that because it's not done underwater.
Think you missed the follow up post.That's not quite correct. Sound waves propogate through water extremely well. Here's an example of a 55 gallon drum getting crushed by atmospheric pressure. You can hear quite a loud pop.
I mean, you step on a tin can and that's a sort of implosion and you hear the crunch....
But that's in open air.
Try crunching a can with your foot next time you're standing in 4 ft of water.
Now imagine 2.5 miles down and 350 miles from the nearest land mass.
I will lose my mind if this conspiracy gains nationwide traction.
Then how do other submarines hear other ships bulkheads imploding?Think about it. An implosion 2.5 miles underwater in the middle of the ocean.
The sub had no explosives or fuel on board.
There were no sound waves for anyone to detect. Physics 101.
Then how do other submarines hear other ships bulkheads imploding?

Umm, not quite.Sound bends toward cooler temperatures. If you’ve ever heard someone shout across the lake the temperature differential between the air and lake creates an amplifying effect.
In the water, especially as you go lower, this same effect takes place. This creates excellent long distance communication lines (where the sound is bending toward cooler temperatures) but also creates excellent dead zones or hiding spots (sections where sound is bending away due to warmer temperatures).

Just so I understand............Donnie B worked with sound/speakers and has stated so many times here and here you are NOW talking sound with a very familiar authority and YOU say you're not Donnie? FFS..............we're NOT stupid.Umm, not quite.
First sound doesn't bend. Sound propagates in a spherical pattern. It can reflect and refract, is that what you meant to say?
Next, lake water doesn't amplify a sound. It refracts/reflects the sound and thereby doesn't attenuate the sound as much as open air (sound attenuates by the square of the distance). Using the word amplify implies some sort of energy is input into the system to make it louder.
Yes, I'm being quite anal here (ya Bag Boy, you have your opening for a stoopid comment) so apologies for that.

Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not "see" a target that would ordinarily be well within sonar range.
If you are sitting in a boat, a sound coming from the shore will seem louder than the same sound heard by a person on land. Sound seems to be amplified when it travels over water.
They don't bend like a curve ball. They are reflected and refracted like a billiard ball.Sound waves don’t bend?

You do not agree that the reflection and refraction of sound off of the surface of a lake creates an “amplifying effect” to the receiver?
