I could do this too. I think most kids could.
Most older people (past 30 or 40 IIRC) naturally lost the highest end of their hearing and couldn't detect the high pitched buzzing of the TV.
This effect has been weaponized by businesses to deter young adults from loitering around their premise. It's effectively a high pitched noise maker in the frequency range that young people can hear, but older people have naturally lost the ability to hear. It's literally just to annoy them into leaving.
