So whatβs the effect? Hearing loss?
In the Navyβs latest environmental impact statement draft, they admit that the sonar exercises planned for 2014-2018 may unintentionally βharm marine mammals 2.8 million times over five years.β This estimate is up about 150,000 instances a year from their EIS statement of 2009-2013. Included in this estimate are two million incidents of βtemporary hearing loss,β and 2,000 are targeted for permanent hearing loss.
So is that how it went? How have things gone in the ten years since this article was written?
There are no noise-cancelling headphones to stop the U.S. Navyβs 235-decibel pressure waves of unbearable pinging and metallic shrieking. At 200 Db, the vibrations can rupture your lungs, and above 210 Db, the lethal noise can bore straight through your brain until it hemorrhages that delicate tissue. If youβre not deaf after this devastating sonar blast, youβre dead.
Fun fact, sperm whales can generate a sonar click at 230dB. Decibels are a logarithmic scale so increasing by only a few dB is basically double the volume.
A sperm whale may swim past you, think youβre interesting and give a little click to scan you, and basically stun or kill you instantly.
Is there any example? Iβve never heard an organism (fish?) killed by whale sound wave like this
One. Ping. Only.
That diving team just fought Sindel and lost harder than MK9.
porque dead?
Sonar use actual sound waves to find things, and the intensity of it is so great that it can kill you. Basically, your brain explodes from how powerful it is.
Is that the Nautilus? SONAR hasnβt looked like that in a while. Also, they dead.
