 Produced by a super-powered loudspeaker known as the Long Range Acoustic Device, or LRAD, this noise can cause permanent hearing loss and crippling pain, yet police officers continue to deploy this so-called "sound cannon" on protesters. 

With help from tech journalist Lynne Peskoe-Yang and activist Michele Lindor - who recounts her piercing experience of being hit with an LRAD - host and sound expert Dallas Taylor breaks down why this "auditory tear gas" should never be used as a form of crowd control, and how it continues to gain popularity despite lawsuits and staunch opposition from audiologists. 

 Twenty Thousand Hertz has made "some noise" in the podcast industry in the last year. In August 2020, the podcast became part of the TED Podcast Network and celebrated its 100th episode. Since then, it has doubled the frequency of its episodes in 2020 and surpassed 15 million lifetime downloads.
