This is a most excellent place for technology news and articles.
How I hate those "new" web pages spending 8 pages on fluff before even explaining how it works.
Thank you Google algorithm (it detects how long time you spend on a page after a search).
So after scrolling up, down left and right, I didn't find it (guess it's sound?).
Interesting. The link jumps straight to the article for me. No guessing involved. Yes, it's mechanically produced ultrasonic tones.
That was incredibly interesting.
My aunt and uncle still had a TV with one of these things when I was growing up in the 90s (the 70s version). The buttons had a distinct and satisfying click to them.
There was only one volume button, and and each press would turn up the volume in 3-4 steps and then cycle around to mute. You couldn't turn the volume down without turning it up first. If you wanted more fine control you still had to get up and adjust the volume knob on the set.
I wonder what my aunt and uncle eventually did with that big old box. It belongs in a museum.
Modern design is boring and ugly as hell compared to what engineers and designers were able to come up with decades back.
Genius is in simplicity
