If a person was to hear an extremely high pitched noise, would their ears bleed? If yes, how else would the sound affect them? Would anything else bleed (nose, eyes, other orifices???)? Would they get disoriented? Dizzy, perhaps? I'm giving a siren this ability and would really like to know how sound can damage a person's body. Please and thank you.
Heyhey! So let’s talk about ears, baby! (Let’s talk about
you and me!) I could not f ind a gif of a siren blasting out somebody’s eardrums, so here is a puppy howling:
First off, the concept of ears bleeding because of a pitch , or frequency, of sound is a pure BS trope that Hollywood likes to play. Bleeding ears look dramatic, but human ears deal very well with extremely high pitch. Beyond a certain threshold we simply can’t hear it anymore. That’s it. The end.
However, the tympanic membrane (eardrum) can rupture because of volume. Sound exists in pressure waves, and the frequency of those waves is immaterial to your desired effect, but the amplitude (volume) is not. An extremely loud siren-character might be able to rupture tympanic membranes by producing overpressures.
Now, there are going to be some other effects from this, not the least on the sirens themselves; since this is SciFi™ I’m going to say that for that one, the Rule of Reality applies.
As to the victim, I’m now basically considering your siren to be a bomb, in terms of pressure waves. That means that the “blast” is going to produce results similar to primary blast injuries. Solid organs are going to do pretty well with this, actually, because sound will just vibrate right through them. But hollow organs, especially the lungs, stomach, and small intestines, might run into problems, because all of a sudden the pressure on one side of a membrane is very different from that on the other.
In short, this could cause issues with internal bleeding in the lungs, and the gut. Also consider structural damage in a cone shape that radiates outwardly from your oh-so-loud siren. It could also potentially throw people backwards across a room.
Oh! One last point. As to your dizziness question: yes indeed, this could cause dizziness. Also deafness. And, uhh. Possibly death, if a building falls on them.
Best of luck and happy holidays!
