The actor is engaging young audiences again with “Sound Detectives,” a comic mystery podcast that teaches the art of listening. […] a new podcast for audiences of elementary-school age that is part whodunit, part science exploration and part comic adventure.

Link to podcast. It’ll be ten episodes long. The first episode came out Wednesday, with a new one each week until early next year.

“Sound Detectives” visits places like Yellowstone National Park, the NASA Jet Propulsion Laboratory and the streets of Bangalore (now Bengaluru), India. When creating the missing-sound mystery for each half-hour episode, Smith and Sokolowski said in a video interview that they sometimes started with a site they found intriguing, and at other times with a sound. The sounds they chose can be challenging to identify; one example was recorded on Mars.
