Beatboxing, as musician Tom Thom was doing in that last example, uses the voice to mimic 1 an incredible range of percussion 2 instruments, from drums, and symbols to records scratches and digeridjuz.
But to make such… well, inhuman 3 sounds, the performer can torts various parts of the vocal 4 tract 5 and pushes aerial high velocity 6 through the larynxs, creating concerns that beatboxing might lead to long-term vocal damage.
So researchers took a close look at what happens inside the throat as the beat goes on. They snaked thin video cameras through the noses of four male beat boxers 7 to watch the voice boxes during performance. The study found that beatboxing is actually probably safer than normal singing or the screams of a rock star, because the glottis between the vocal cords stays open more and the force doesn’t get concentrated in any one spot. The work appears in the journal of Voice.
