The satisfying click of a car door. The snippy voice of Siri on your phone. The sudden
explosion in your favorite action movie. These everyday sounds, as well as some unusual ones, are examined in a new podcast that delves into the stories — and the people — behind the creation of sounds, encouraging listeners to be more aware of this sense.
The "Twenty Thousand Hertz" podcast, named after the highest frequency that humans can hear, is a nod to all the audio phenomena we encounter on daily basis. The next episode is scheduled to be released today (April 4).
In a recent episode, listeners get to travel from Mercury to Pluto, and learn how sound waves would change on different planets. NASA scientists on the podcast explained that sound would be unable to move through the vacuum of space. But on Venus, for example, the carbon dioxide-rich atmosphere would be so thick that if humans could go to the planet and listen to its storms, they would sound as if they were muffled. On Mars, the Red Planet's atmosphere is thinner than Earth's, so there would be very few molecules for sound to move, the scientists said.
