    40 hz is called "Gamma Band" (Neural Stimulation)

    5 - 9 Hz - brown note


    30 hz - parkinson

    40 hz - alzheimers

    ... external stimuli ...vestibular system ... ?
    does this frequency "loss" have something to do with unexplained hearing loss ?

    after googling it seems a stupid question: would it be possible to display the hz-frequencies in youtube-music ?

    to find out if you can hear 40 hz at all ...

    ... perhaps some AD patients may not hear much at those low frequencies, and thats why they use flickering LIGHT-40hz to activate it?

    wondering, if 40hz-light-flicker-therapy may restore a neurosenso-hearing-fail at 40hz... ?

    on youtube they have a range of test tone videos https://www.youtube.com/playlist?list=PLzFvCAfIq7a2SIBfDhpCytfJ4RHVb_KLY

    Anybody got a device capable of playing back 40Hz video as intended? My Tv or monitor can't, they weren't designed to - 50Hz to 120Hz is what they were designed for, with the odd trip down to 24Hz in the case of the TV - but 40Hz? - what is the point of having that on youtube?

    @Wonko you think, 40hz lights on youtube are not played on the laptop with 40hz ?

    im searching for a light bulb with this flicker frequency ... "light therapy", possibly

    How could a 50Hz device accurately display 40Hz without generating an interference pattern of some sort? Even if that's suppressed the result wouldn't be a 40Hz flicker but some hybrid.

    I may or course be wrong, but several years ago I spent a fair amount of time, effort and money trying to get around a similar problem, using conventional equipment, that was causing rendering/playback issues.

    Just coz the source is fine, and the playback device can handle it, doesn't mean the renderer can (in this case a monitor/TV).

    ETA - 40Hz sound is incredibly annoying, and the video, yes it has interference when played back on my 50Hz TV, or even at 60Hz - it might be okay at 80Hz but I can't seem to do that, 79Hz is the closest to 80Hz I can get.

    I now have a mild headache, from under 20 seconds of exposure to the video. Not complaining, just something for others to be aware of.

    It sounds a bit like a swarm of insects if you've ever heard one of them, possibly on a nature program or horror film. Just deeper and quieter. No idea why it's annoying but it was.

    sounds like my "tinnitus"-thing... :)

    there is another interesting article, how they found out about AD-frequency (2018)
    https://www.nature.com/articles/d41586-018-02391-6

    but .. the engineered AD mice are not perfect matches to human AD (though, it seems the frequencies indeed help in humans)
    and "Gamma oscillations are the type most likely to induce seizures in people with photosensitive epilepsy"
    and amiloid is produced for protection i understand, so it may make sense that its there (the lesser evil, sort of)

    When I first read this, I took "bathing" literally. :)
