I would be pretty annoyed? I am a teenager. I am usually always walking around with music playing in my headphones. I’m sure if kids wants to be annoying, it would take more than an annoying sound to stop them? Also, what if not every teenager in the area is being annoying? In the question you mentioned, a user says that people sometimes pass out because of high frequency sounds. People may have health issues, and those high pitches sounds could trigger something, I don’t know. Seems stupid and just pointless
