Back in the day I could walk into a room and tell you if there was a monitor on. End of the day I just had to open the lab door to hear if anything was still on. Now I have to go look. My hearing is clipped at about 13,600 Hz. My students think it's a riot. That's when I crank the generator up to 17kHz and then they play nice. Played through a loudspeaker in public it's known as a "yob deterrent" in the UK.
