Sound gets funneled down your ear canal and… then what happens? You’ve heard about drums, tiny bones, and a spiraling hearing sensor but not like this. Hear how sound is translated to the brain from people who study our hearing (and speaking) systems for a living.
This is the fifth piece in a series about the information found in sound.Contributors to this piece can be found here.
In this episode Prof. Shamma talks about “beams” in the inner ear that vibrate in response to their specific frequency. Here is another scientist, Prof. Christopher Shera, explaining the same interesting mechanism:
Avery Wang helped found the app, Shazam. This app is now part of our cultural consciousness as a flagship app of all smartphones because it is so simple – hold up your phone to a song you hear and identify it with this app. It’s almost magical. This is the story of how Shazam began (with the many hurdles Wang overcame) and how it works.

Don Hodges studies music psychology. Here, he discusses one of his latests studies that gives us some insight into what our favorite song (and music in general) means to us on a neuronal level. He then paints a beautiful encompassing view of how humans appreciate music. Listen below.

Bernie Krause is a musician who has drastically shifted his career to study natural soundscapes. He’s discovered information hidden in these natural sounds that are telling for animals and us. Hear how animals sound like instruments in an orchestra and how they are quieting.

A fetus begins to respond to sound at 18 weeks old. We are bathed in sound every day of our lives and yet it isn’t clear what exactly the phenomenon is because it isn’t as visible as, say, light. In this small episode we dissect the outward physical description of sound and also touch on the main aspects of the subjective perception of sound. Learn why instruments and voices are recognizable and why we can learn to echolocate.

In the last installment of our Origins of Life series, we join people for their first look at Saturn alongside astrophysicists who gaze up at the universe for a living. Learn the new techniques scientists use to FIND planets in other solar systems (exoplanets) and hear their thoughts about life in the deep void of space.
The secrets of earth’s early history (about 4 billion years ago and called the Hadean period) have only recently been discovered thanks to the efforts of scientists like Steve Mojzsis. In this episode, Mojzsis talks about what it must have been like on the “peculiar” early earth. Other scientists weigh in on how life changed the planet. Finally, a perspective of the future of the ever-changing planet.
Life is everywhere and we have a tough time killing it when sending our spacecraft off to Mars. However, in the lab, life is elusive. We look at the problems in origin of life research and when faced with such difficulties, why scientists persist in this research program. Surprisingly profound answers in this fourth installment of our Origins topic.
