Would it have been possible for the speakers of the time to emit those frequencies? Imagining the equivalent of a Twitch raid: "I'm done broadcasting so I'm going to send you to the next channel."

We had a TV that used ultrasonic sound to control the TV, When I was young I could fairly hear the tone from a couple of the buttons, though super faintly, but the dog would cock its head when certain buttons were used.
