My favorite endangered sound is probably too subtle for the museum and, alas, one I can no longer hear anyway: the 15625 Hz squeal of an NTSC cathode ray tube TV.
I can remember knowing whether the TV had been turned off or was just on mute (with no video input) well into the 90s just by the sound.
- cameronh90 5y agoWhat age did you stop hearing it? I assume if we had a future hearing aid that bypassed the eardrum and connected to the nerves directly, we could hear long lost frequencies again.
- r_klancer 5y agoI don't know. The last time I regularly used a standard def CRT TV was in 2005. Pretty sure I could hear it then at 30-ish. Sometime last year I pulled up a Youtube video that plays a rising tone up through 20kHz. I stopped being able to hear the tone somewhere between 10kHz and 15 kHz. My kids could hear it fine. The sound lives on in my memory. I can vividly remember the squeee of turning the TV on. Actually I can hear it right now! But I believe that is something called "tinnitus" :)
