（单词翻译）

 Beatboxing, as musician Tom Thom was doing in that last example, uses the voice to mimic1 an incredible range of percussion2 instruments, from drums, and symbols to records scratches and digeridjuz.

 
But to make such… well, inhuman3 sounds, the performer can torts various parts of the vocal4 tract5 and pushes aerial high velocity6 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 boxers7 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.
