It's true that certain incandescent light bulb filaments do "sing". Some more than others. If you have one which "sings", and it's on a dimmer, you can actually vary its audible output.
Now you know.
I have a friend who claims he can hear ultra sonic alarms. That's why he can never take his wife shopping. Bother his ears too much.
"I have a friend who claims he can hear ultra sonic alarms. That's why he can never take his wife shopping. Bother his ears too much. "
From what I've gleaned it is not so much hearing but a sensation.
Related : Many years ago I read that they were adding AC high frequency bias to hearing aids. This after some hard of hearing reported being able to hear better in the presence of ultrasonic alarms.
I am pretty sure they stopped the process and I think I know why. Because that constant high frequency tears the cilia in your inner ear up even more, accelerating hearing loss.
ROFLMAO smart man
