Presumably high frequency. Older people aren't that good at hearing high frequencies. But it's unlikely it would suddenly stop being audible when you reach 20.

I took it as, there are kids who hang about, sitting on the NTL street box, and they swear at a woman with mental problems on his street, presumably to provoke her. And he feels that these are the type of people that need to be targeted with dispersal methods.
