Nobody ever believed me when I said I could hear a powered-on CRT from two rooms away

[-] davidgro@lemmy.world 47 points 2 months ago

I'm in my 40s and still can hear that frequency just fine. Probably not as loud.

One of my least favorite types of thing are those "teenager repellent" devices.

Also certain induction cooktops.

Also the "kid repeller" devices (because yes, it also includes younger people such as infants, and also older people), is that it just makes the world a hostile place for young people, and then later people turn around and complain how "nobody goes outside anymore"

In addition, this severely affects animals too

We don't have a range, and I use portable 110v induction cookers. I love them so much, but I must have music or YouTube or something playing while cooking, or I want to stab a fork into my own ears

[-] tal@lemmy.today 3 points 2 months ago

I don't think that there's any fundamental reason that an induction cooker needs to be doing anything around 20kHz. I'd guess that it's just the power supply happening to be flipping power on and off at that frequency.

You could probably just get a different cooker.

[-] dharmacurious@slrpnk.net 1 points 2 months ago

I've got two, I've had 3 in the past. They all do it. I have no idea what the frequency is other than "painful and barely audible"

[-] Duamerthrax@lemmy.world 7 points 2 months ago

They put those “teenager repellent” devices in malls. And what do you know, malls are dying.

My favorite use of those was teenagers using that as their ringtone so the teachers couldn't hear it.

Some kids at my high school tried that on their phones, but it never worked because all the other kids in the room would cuss them out for basically inflicting the entire room with mosquito-in-ear noises.

I wish I knew. It was in the cafeterias at work, and I would be the only person in a room of a hundred who was standing there plugging my ears and cringing from the pain.

[-] Speculater@lemmy.world -2 points 2 months ago

I love those things lol. I'm your age and can't hear shit above 13 KHz.

I hear the chirping of shoes on televised basketball games. No one believes it until you meet someone else who can hear it too. Some people can just hear higher pitch sounds.

Edit: and yeah, I can hear when a CRT tv is on.

[-] Visstix@lemmy.world 19 points 2 months ago

Wait, most people don't hear that?

[-] jaybone@lemmy.world 7 points 2 months ago

I don’t know. I thought everyone could too. Until it turned into an argument at like thanksgiving or something. I don’t watch sports but the rest of my family does.

[-] snooggums@midwest.social 5 points 2 months ago

Maybe the rest of your family is just so used to it they ignore it.

[-] The_v@lemmy.world 4 points 2 months ago

The chirping noises from shoes is so annoying. When I watch college basketball it's with the volume off.

[-] flambonkscious@sh.itjust.works 1 points 2 months ago* (last edited 2 months ago)

Most people don't actually pay attention to their senses - I think the brain happily filters it all it out.

I think as I'm getting older, I'm either more aware or it's getting worse

[-] The_v@lemmy.world 6 points 2 months ago

The whine on larger the TV's were so damn loud. My neighbor's had one of those massive beasts of a CRT. I could hear it 100 feet away.

My first migraines where triggered in the computer lab from 40 CRT monitors being on. It was so loud and annoying.

[-] TheRedSpade@lemmy.world 3 points 2 months ago

TIL some people couldn't hear them.

[-] xthexder@l.sw0.com 1 points 2 months ago

Well I definitely can't anymore. Either that or there's been several CRT TVs on around me ever since I went to that loud concert...

[-] TheRedSpade@lemmy.world 1 points 2 months ago

I guess I technically can't anymore since I don't even know where to find one these days.

[-] orphiebaby@lemm.ee 2 points 2 months ago

I've been telling people for a while that I can hear it too. Nice to know I'm not the only one.
