Yes. I can hear to about 18kHz, so cheap USB chargers are no longer allowed in my house…
Worse, the EV chargers I used to work with had PEMs switching at 10kHz for the US UL variants. EVERYONE could hear those!!
Test your hearing range with this if you want…

I used the 10kHz tone to annoy the eng dept in the office till they changed the PEM switching freq to 20kHz…
