Around 10khz is my musical limit, although I can hear higher frequencies. i.e. given different pitches around 10k, I can tell them which is higher or lower.
An ear doctor can test your with standardized medical equipment. It's usually free. Even if you don't have hearing problem they can still check your ears. Just like you should get your eyes checked even if you don't wear glasses.
Somebody may be able raise their hand to when they detect something at 15khz, but I doubt it's intelligible after you're a teenager. I saw a show on a kid 12-year-old math genius. He fooled an expert who's job it is to test and confirm real higher level abilities. This tester was looking for anybody feeding the kid answers - that was his job and he was experienced at it. Turns out they were feeding the kids answers through mosquito tones. The tester couldn't hear these tones. He was middle aged. They were 16khz tones, and the kid still had problems hearing them sometimes. Other noises interfered.
Maybe you can raise your hand with no other sounds are playing, but louder sounds always mask quieter ones, And midrange is going to dominate in human hearing.
The gold standard of Hi-Fi was FM radio for a long time. It is limited to 15khz at the highest.
Simple smartphone apps can detect high-frequency and the actual levels.
And talk to the doctor, but excessive noise, even low frequencies can damage high frequency hearing. It's just loud noise in general. Not loud noise at a specific frequency causing hearing damage.
