The next morning, the Underground Man and Enos discuss the latest developments in the field of music.

The LRAD, he says, is like a "scum at first glance" device, because it disables the person who's listening to it. He says that she's probably talking about a new kind of device that's been invented, called an "audio weapon," or an "improvised lRAD."
