Ultrasonic Tracking: Are our phones really listening to us?
Twenty Thousand Hertz - The stories behind the world's most recognizable and interesting sounds.
Did you know your phone is a really good listener? Apps on your phone might be sending and receiving data over ultrasound. Ultrasonic communication is used for everything from tracking your daily habits to enabling light shows at music festivals. We hear from Yale Privacy Lab's Sean O’Brien and Michael Kwet, and privacy and technology counsel Katie McInnis. We also discuss the more positive uses of data over sound with LISNR CEO and co-founder Rodney Williams.
Twenty Thousand Hertz is produced by Defacto Sound.
