Boxers who emit different sounds with their tongue and their mouth can not only be heard, but also be seen in real time thanks to the MRI images taken by researchers from the University of Southern California (USC) .
Real-time MRI images were recently presented at a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association in Victoria, British Columbia, Canada on November 7, according to a report published recently by Popular Science.
MRIs show different tongues of boxer beating in the mouth while emitting 30 different sounds, or what the researchers call a "glottalic gliding slip without a voice" or a "glottal glottal stop expressed by a voice" , according to the article.
The research team of linguists, engineers and computer scientists asked each drummer to spend 30 to 90 minutes playing sounds he knew while an MRI was recording slices of head and stuffy. They were also asked not to move with the rhythm of the sounds they produced, as this would produce poor quality images.
"[Beatboxers] are trying to create a new sound system," the lead author Shrikanth Narayanan, PhD. , engineer at USC, said Popular Science. "We just wanted to see the similarities and differences from the point of view of the cognitive sciences."
