Underwater

[JBL 4645]

What is the pressure of water on the ear while being underwater?

What I mean is. What frequency, specifically will the ear experience whilst being underwater?

I know what it feels like from past swimming many moons ago, just never gave it any thought as to what type of frequency the ear is being pressurized under a few feet of water.

Image is from "The Abyss" (1989) Bud and Catfish take a quick dip thousands feet down. Oh, the pressure of the sub bass!:p my ears are bleeding! :D

the selecter "too much pressure"

Every 2.31 feet of water adds 1 PSI. 1 Atmosphere (bar)= 14.7 PSI. So atmospheric pressure doubles at about 34 Feet or 10.4 Meters. Therefore, pressure at 104 meters = 147 PSI above atmospheric pressure or 10 Bar. 1040 M = 1470 PSI or 100 Bar and 10400M (6.5 miles) = 14,700 PSI or 1000 bar = 1000 times greater than atmospheric pressure.

The above is for clear water. Salt water is 2.5% heavier.

There is no "frequency" of water. However, like air, water will conduct acoustic energy.

So there is no 10Hz no 20Hz no 30 or 40Hz of low end pressure right!

Yes, yes "PSI" pounds per square inch.

Might well get a bucket and fill it with sand and balance it on your head, to get the idea of what pressure feels like.:p

That’s all I need to know.
Cheers:)

You are going to need one big bucket...


14,700 PSI = 1034 Kg/square cm. = 1,058 tons/square foot...

That'll put a dent in a few things..

No just a single small bucket will do fine, thanks.

I don’t want to compress the whole building down to the size of dolls house. LOL :p

Cheers on the info.:)

The scene in “Titanic” (1997) doesn’t feel anything like what it should. Maybe Skywalker Sound should have put extreme overkill, overkill sub bass on the underwater scenes with the submersibles.

It’s amazing there unopened bottles on the wreck site where the pressure hasn’t got to it. 3 ½ tones is lot a weight.
