Low Frequency Active Sonar Gains US Gov. Approval
burntout writes "According to bbc online the US government has finally approved the use of low frequency active sonar. Apparently the navy has been granted an exemption from the marine mammal protection act for this, which is apparently 'necessary because of new superquiet Chinese, Russian, and German subs'."
Active sonar is only used in emergency situations
:)
Not entirely true.
Sometimes it doesn't matter if you advertise your position. Active detective ranges are so much longer than passive detection ranges that sometimes it's possible to just ping like hell and hold the threat at standoff range until you are ready to kill them.
To provide excuses for any action. Destroying the world's most peaceful creatures because we want to kill each other is ironic and disgusting.

Can you imagine a sound so loud that it kills you? It's mindboggling. Not a nice way to die. I have heard estimates as high as 235 decibels. That's a hundred thousand times louder than pressing your ear up against a jumbo jet engine.
