I like sound synthesizers and there's an on-line "Binaural Beats" generator here https://brainaural.com/
Aside from its intended application, it has a stereo pan function where, according to a provided LFO, it'll sweep a tone back 'n forth between the left and right channels. That tone can be set from 27 Hz up to 14 kHz. So you can take a tone, slowly (say, 1 Hz) pan it left / right and listen to that using headphones.
Why? To see how, or if, your ears work. Mine are like old tires that have never been rotated, 1/2 the tread gone on one side.
2.5 kHz the tone sounds about the same as it pans left and right.
3.5 kHz I'm aghast to find the pitch doesnt sound the same in each ear. Twee in the left, dell in the right. Swap the cups - same thing.
4.1 kHz right hears it, left not nearly as much.
8 kHz on up, only the left hears anything...
10kHz perception of anything in either ear gone.

I wonder then why I clearly hear on a digi EQ which works precisely putting up 20khz or anything beyond 15khz.
With 30years you usually cannot hear 15khz any more.
There is the theses that the ear can hear the higher frequencies in music (mix of tones) but less on single sine wave tones.

Use a simple sine generator to test your hearing (range). Example: https://www.szynalski.com/tone-generator/
You need a playback device that can reproduce the frequencies you're looking to test. A smartphone for example likely will do very little anywhere outside 100-10000 Hz. Test results can be wrong, or let's say misinterpreted, if you use playback devices that aren't suited for the task.
