If you drop an audio buffer and fire off a 22kHz impulse into a 50,000 watt soundsystem, you are going to have thousands of very unhappy people and likely some hearing damage.

Point taken, but 22khz is too high for people to hear I think.

You don't need to perceive a sound to have your ears be damaged by it.

(This goes in both directions on the spectrum too. You can have your hearing damaged by infrasound as well.)

Ah, this makes a lot of sense, thank you. Much like there are spectrums of light we can't see that can damage the eyes.

Idk exactly what the poster meant but an impulse is broadband, theoretically encompassing all frequencies representable in the host sampling rate.
