Can You Hear Me Now?
Here is a website that lets you test whether you can hear different high frequency tones. I am 34 years old and my hearing cuts off after 14K. Give it a try and see if you have taken better care of your ears than I have. Too much Terminus Victor probably did mine in. (It was worth it, though.)
I can hear 16. Explains why at your old place, there was that high pitched sound that was making me crazy and you couldn’t hear.
