Oh so the sonar is making her ears bleed

Boat engine is deafening under water.

The sight of being underneath one of those ships is fuckin terrifying.

Old thread, but actually, there were a bunch of reports coming out recently that it's indeed sonar that may be responsible for multiple whale beachings. I believe it's the high pitch that is deafening, rather than the low hum of the engines...

Both would suck to experience, really.

She's a shark, not a whale or a dolphin, so I don't know if she would be able to hear that kind of ultrasound.

With that said, the interesting thing with sound propagation underwater is that, since water is a lot denser than air, you can have much more powerful soundwaves propagate through it. Sound travelling through air can't really exceed 170-190 dB, but submarine sonars can send pressure waves of up to 235 dBs (from what I'm reading, they don't specify at what range).

You also have to keep in mind that decibels work on a logarithmic scale, so for every 20 decibels you add, the sound is 10 times as loud.

This (alongside with the linked video in the description) looks more like it would be the sound of the boat over them.

A giant, underwater fan passing overhead like that would be fucking horrifying!

Oh sweet, someone who knows about acoustics, thanks for the info albeit I just noticed...10 months later..

Actually it's probably the ship's screw (propeller) noise. While mammals are not as sensitive to this sound sharks in my experience are, and will oftentimes behave erratically in its presence. A twenty foot diameter prop is unbelievably loud at speed.
