Evolution of Accents
When you describe yourself to others you might mention your height, hairstyle, or maybe your build. But one of the most telling things about you is something you can’t even see, yet it defines you more than you realize. Your accent tells others where you’re from, who you identify with, and maybe even where you’re going. How did accents evolve and why are American accents so different from British accents? Featuring Hollywood Dialect Coach Erik Singer and Linguistics Professor Dr. Walt Wolfram.
Forensic Audio
You might not realize it, but audio can be just as crucial to solving a case than video or eyewitness testimony. But understanding how to interpret audio evidence, or having the ability to enhance it to a point of intelligibility, requires highly-specialized training and expensive software. Meet Kent Gibson, one of the country's leading forensic audio experts, who's done audio analysis for the FBI, the Secret Service, and the Department of Homeland Security, among many others, and get his take on audio evidence from the missing Malaysian Airlines flight, the Trayvon Martin case, and Mel Gibson's infamous domestic dispute.
The Wilhelm Scream

But you may not realize that the most famous scream in Hollywood has a name—and it’s been used over and over and over in countless films, television shows, and commercials. What makes it so good? And how did it become a filmmaker favorite? Featuring Steve Lee, sound designer, film historian, and creator of the Hollywood Sound Museum.
Voice Acting
We hear disembodied voices all the time, in everything from cartoons and anime to commercials and trailers. It seems easy, but it's actually an intricate craft involving a great amount of training. What does it take to create multiple, unique personalities using only a voice? Featuring voice actors Christopher Sabat (Dragonball Z, One Piece) and Cissy Jones (Firewatch, The Walking Dead).
Hearing Loss
Our ears are sensitive, but we often don’t treat them that way. We are born with the ability to hear up to 20,000 Hz. As we age, our hearing range diminishes. On top of that, the more exposure we have to loud sounds, the greater the impact it has on our ability to hear. Find out what happens once we start to lose our hearing.
