Many animals, humans included, are natural-born criers. It’s the most basic form of communication from right when we come into the world. But us humans are unique: we keep on crying until the day we die. What was born as a survival mechanism, develops a deeper fundamental need as we grow older. In this episode, we discover the hard-wiring in our brains that reach across species, and how our tears into adulthood make us distinctively human. Featuring Dr. Susan Lingle, Behavioral Ecologist at the University of Winnipeg, and Dr. Ad Vingerhoets, Research Psychologist at the University of Tilburg.

Noise pollution is something we’ve all experienced. Road construction, motorcycles, passing aircraft - the list goes on and on.

Featuring Les Blomberg, executive director of the Noise Pollution Clearinghouse, and Rachel Buxton, acoustic ecologist, conservation biologist, and postdoctoral researcher at Colorado State University.

We often think of the ocean as a quiet, peaceful place, filled with animals that don't make much noise. So when Christophe Haubursin from Vox went diving in the ocean for the first time, he was surprised at how rich the soundscape was: he could hear fish nibbling on coral and squid swimming. But more than anything, he could almost always hear the hum of a boat engine. It's part of a big problem in the ocean right now — ship noise has doubled every decade since 1970, wreaking havoc on marine life. 

This video was made in collaboration with Twenty Thousand Hertz, a podcast that dives deep into all kinds of stories about sound. Everything from "who's the person behind the voice on your phone," to "what do other planets sound like to our ears?" To hear more stories like this, subscribe at applepodcasts.com/20k.

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.

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.

When it comes to movie screams, what’s the first one you think of? Is it a scream that evokes a sense of fear, pain, or maybe even… humor?

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. Featuring Lindsay Prusick and Shaheem Sanchez (Instagram).
