The Freedom Not to Listen: The Story Behind Noise Cancelation Technology

 In 1978, the U.S. government approached a sound company with a unique proposal. They wanted to develop a specific technology that would allow aircraft pilots and NASA astronauts to communicate clearly with ground crews and other pilots even with the ultra-loud roaring of jet and rocket engines in the background. The resulting technology would later become available for use outside of aeronautic environments; following its use in military headsets in 1986, the technology gradually made its way into mainstream and public usage.

Today, this technology is known as noise cancelation technology, and is used around the world in headphones and earbuds to help people focus on the music, podcasts and other audio that they want to hear while blocking out the sounds that they don’t.
