This is very cool. The harmonic content of a xylophone and marimba is strikingly different.

I have tinnitus at various frequencies, including about 16kHz. It interferes with hearing tests.
It took about 25 years to get used to it enough that it didn’t drive me crazy, but now seems to be getting louder again. Drat and double drat.

There was a quite successful series of experiments done a while ago of transmitting high frequencies in public places at night that were notorious for marauding gangs of younger people. It couldn't be heard by older people but made the younger ones feel 'out of sorts' so would disperse.

The sound you hear from a speaker has little to do with any of its published specifications. The sound you hear from a speaker is heavily influenced by the room it’s in, such you we never hear “a speaker” but rather it’s interaction within the room, what it’s connected to and what it’s playing.

I can hear to around 13 kHz. I’m 50, so that is fine with me. I figured my hearing range would drop as I get older anyway.

I have permanent hearing loss from when I was a kid, about 95% gone in one ear and the top end above about 15KHz in the other. So I at least have one good one to work with and just barely enough that I have some 3D hearing perception in a clean acoustical environment. In a noisy environment? Yeah, pretty useless.
With all missing above 15K, I always wondered if my/any speakers were actually reproducing it but I brought a test CD to a friend's house when setting up his speakers and played the inaudible (to me) sound without describing it, and he heard and described it easily. Lucky bastard.

I used to be able to hear to about 21 kHz. Walking into stores with ultrasound motion detectors made my teeth itch. When I was 24, I returned three TVs because the flyback transformer noise made me uncomfortable. I ended up with one of the last Mitsubishi models made in Japan. I don't know if it was better quality construction of the electronics or the hefty wood cabinet damped the noise to make it acceptable.
Working in a loud industrial plant for 10 years ended that even with wearing earplugs most of the time. Coming up on 30 years later, I am on the border of needing hearing aids.

just checked with ProTools osc.
34Hz to 15,500. That 15,500 is no doubt my left ear only.
Prolly 10k in my right.

Mine blew out during a Grand Funk Railroad in 1970 or 71 when I stood right in front of the main speaker the whole concert.

16k was the frequency of a CRT flyback circuit. Been awhile since I have been around a picture tube.
Interesting. When I was younger, I could always hear a certain very-high-pitched sound when a TV was on nearby, even when the sound was off. I suppose it might have been that.
