(单词翻译:双击或拖选)

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.
