The weird part, though, is that I can't find any articles about how such sounds might affect other things.
Like, what if a team of SCUBA divers had these high powered megawatt level infra-sound transducers aimed directly at them, and felt the brunt of such a wavefront at close range?
Would they even hear it, or maybe just feel it? Would they get a concussion? Would it shake them so violently that maybe they suffer massive full-body bruising, and even hemorrhaging or worse?
This is the part that seems unclear. How do these noises compare to something like the shockwave of a depth charge, in terms of energy imparted on other objects suspended in proximity? What happens to, oh I dunno, fine structured ballistics gel replicas of sensitive organs?
- xjwm 10y agoHaving spoken with Navy divers on thia issue, it could range from unpleasent to fatal depending on how loud the active is, and distance from the transducer. Before a dive, verifing that no ships nearby were planning on transmitting was a required safety precaution. Someone smarter than me could probably figure out what dB level actually causes internal damage.
- Rifu 10y agoA cursory google search gives the number 170dB as potentially fatal. [0] [0] https://www.reddit.com/r/NoStupidQuestions/comments/30xga2/if_a_sound_of_500db_goes_off_for_lets_say_0001/ https://www.reddit.com/r/NoStupidQuestions/comments/30xga2/i...
- entheon 10y agoThat description is lackluster. A train horn is 130, okay, we've all been too close to a train horn, and it's unpleasant. But everything else in that reply is hypothetical, with not even serious, realistic, testable anecdotes to support the claims. Without supporting evidence all it says is: 150 db is bad. 160 db is bad. 170 db is bad. 194 db is bad. 185 db is bad. (tornados) 220 db is bad. (bombs) 250 db is bad. (bombs) 310 db is bad. (volcanos) 325 db is bad. (stratovolcano) 500 db is bad. Lots of "*beavis, that would be cool!" and not much else.
