Beatboxing is a musical art form in which performers use their vocal tract to create percussive sounds, and a team of researchers is using real-time MRI to study the production of beatboxing sounds. Timothy Greer will describe their work showing how real-time MRI can characterize different beatboxing styles and how video signal processing can demystify the mechanics of artistic style. Greer will present the study at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
