An international research team has unlocked the mystery of how Tuvan throat singers from Mongolia produce different sounds in which you can hear two different sounds simultaneously. Fascinated by this form of throat singing from central Asia, known as Khoomei, researchers from Western, York University and the University of Arizona examined the vocals of the members of the Tuvan performing group. The researchers observed that Tuvan singers were able to uniquely compress their vocal tract one at the front of their mouth using their tongue and another at the back of their throat to produce dual sounds. The Tuvans have been famous for making sound through such precise control of their vocal track that they can sort of tease these things out and produce concurrent sounds.
