That reminds me of the old crt tv my parents had for ages in their room that i could hear from the other side of the house but they couldn't that made the most awful high pitch whine. and as the screen would go black in some sort of sleep mode but it kept making that horrible noise with the only indicator that is was on still other than the noise, that apparently only i and dogs could hear, was the color of a small dim recessed led. they got rid of it a about three years ago but whenever i would visit I'd hear it as soon as the door opened and it would drive me nuts till i got the chance to turn it off.
Most children can hear very high frequencies and it usually causes them discomfort. For a while it was actually used as a deterrent for loitering youth in the Netherlands (the "mosquito device"), which was terrible for me: as an adult I can not only still hear that, but it's almost unbearable.
Very old CRT monitors can have a similar effect, but they are usually not that loud. A friend once tried to test it using one of those "silent" ringtones for kids and I nearly destroyed his phone, without meaning to react so strongly.
Many years later a niece was able to ask an expert about this and he told her it's probably "cochlear hyperacusis", something that can make you overly sensitive to certain sounds or frequencies.
I do not have any other hearing issues, except for a single 20 second burst of tinnitus that will start loud and quickly taper off completely, which only happens maybe once every 6 months or so.
I am in my 30s and still hear frequency's over 16.5 kHz. I cant stand the high frequencies they are like auditory needles in my ears still. I know they say adults dont hears them but is that actually the case for most adults? I mean I have done enough it seems like I should have the hearing damage needed loud music on headphones, been in rock concert mosh pits, fired guns without hearing protection, fireworks, fired homemade cannons without hearing protection. But still hear everything fine
15.625KHz to be exact. I can hear this sound quite well, to the point where I prefer not to be in the same building as any CRT that emits it.
There are those that don't, mainly newer models I assume. I think it has to do with the exact shape of the waveform that drives the (horizontal part of the) deflection yoke. Some of them are noisier than others.
Same. As a child, I could be reading a book at one end of the house and I would experience discomfort (experienced as a slightly painful "pressure" in my ears) when the television, which was 4 rooms away, was powered on. My family didn't believe that I could tell, because to them it was silent. So they challenged me to a double blind test, and were surprised to find that yes, it really was the TV that was bothering me.
Related, we did a hearing range test in a high school science class. I could detect the tone generator at a frequency well beyond what anyone else in my class could pick up. I couldn't hear it as a sound anymore after a certain point, but could still feel it as an uncomfortable "pressure" inside my ears.
One of the power supplies I own makes a high-pitched whining sound from its fan. It's the most terrible, obnoxious sound, but I somehow don't mind it. It blends into the background after living in it for years. Still, when it goes away, there is nearly unparalleled silence.
Took me a while to realise that I could hear those, but also that I have tinnitus at the same level. For quite a while I assumed someone had turned one on nearby, until it dawned on me that no, I also have tinnitus
