    That’s something you might lose over time, that’s why some places would install speakers with certain sounds outside their door, kids wouldn’t hang around because it disturbed them, older people just didn’t hear it.

      Unless you’re autistic. We don’t lose the top end of our hearing for some reason. Those “mosquito” devices can trigger my migraines, at 43 years old.

        don’t think that autism has to do with it. The cause for the higher frequency hearing loss is a physical degradation of the small hairs in the cochlear. And in some people it just happens a lot less

          No, really. It is very common for individuals on the autistic spectrum to have above average acuity of high frequency sound.

            Fuck. I’m 35 and I was able to hear a failing ballast in a light fixture at a busy reptile expo.

            I have a spectrum analyzer on my phone, which I had to use to prove to my wife that there was a loud high-pitch whine, and that it wasn’t tinnitus or a phantom sound.

            This would be a weird way to find out I’m on the spectrum.

            Could it be a result of not liking other loud sounds? Loud music, concerts, loud crowded places, headphones played too loud etc all can damage your upper range hearing, and iirc many on the spectrum do not enjoy loud stumuli.

        If a “friend” detonates an IED firework in an abandoned field near your head you will lose that top end… But you will also get really bad tinnitus.

        We don’t? I can still hear the whine of a CRT. I don’t think I have ever heard a mosquito alarm. Maybe I wasn’t paying attention.
