No wonder those whales and dolphins get lost and end up beached! LOL

That info is highly classified! I wouldn't know.

All I can tell you is...

My name is Ben Dover, my SSN is 867-5309, my wife's name is Jenny, my favorite food is green eggs and ham.

This is all I am liberty to say!

I would think decibles depend on the power of the system. More powerful more noise, less powerful less noise and I doubt if any two classes of sub are the same.
One way you can get a feel for sonar effects is to fill your tub and pass gas with your head underwater.

LOL! Please tell me you haven't done this! Oh Geez!

I was thinking more on the lines of taking a hammer or something metal and heavy and tapping that hard on the tub while your head is underwater. It can get a bit loud especially since the water is contacting your eardrums and water weighs more than air! This is why sound can travel further underwater than air. Air tends to "float" away sounds and water tends to "hold" them. It's also got something to do with the "echo" effect. Things underwater travel a long distance and come right back to their sender, hence active sonar pinging.

"The council said some mid-frequency sonar systems produce 235 decibels, as loud as a Saturn V rocket at launch."

In one navy's submarines I believe it takes a key held by the captain to activate the active sonar.
