The Long-Range Acoustic Device, or LRAD, was developed for the military for long-range communication at sea. But this ear-splitting device has also been fired on protesters across America, resulting in lawsuits and permanent hearing loss. In this episode, we explore the history, science and effects of the so-called “sound cannon.” Featuring tech journalist Lynne Peskoe-Yang and activist Michele Lindor.
