Never heard of hear high pitched tones thing from hair dying. Been hearing that high pitched sound in my head since I was a kid so I doubt it has anything to do eith the government not that some of them aren’t. I ave noticed the intensity is stronger than it used to be do there might be something to “dying hair” theory (but I certainly hope not...: ( )
Hair cells are in the inner ear and are responsible for hearing and also for balance. The sustained tones, which sound for a brief time and then vanish forever, and which can be high, medium or low, are the onset of age-related hearing loss. We never hear that particular tone again. The hearing loss may also be associated with exposure to loud noise or some medications. The subjective sounds, like a high-pitched ringing or the sound of static, is usually what is called tinnitus.
You probably know this, but your response was funny.
