You're walking down a street in New York when all of a sudden, 'Who's that?' — whispers a woman's voice. 'Who's There?' No. You weren't having a schizoid episode. You were being subjected to 'sound in a narrow beam, just like light' without your permission. It was coming at you from a rooftop speaker 7 stories up. Don't want to be bombarded by sonic ads? Tough. Wear ear-plugs."
