Talk:Sounding board

Does figurative use belong in this article?
The term sounding board can literally mean the voice reflector (this article) or the musical instrument part (Sound board (music)). Both are correct usage. But this article is about the former not the latter. It also mentions the figurative usage. However, I don't see any evidence that the figurative term is based on the meaning discussed in this article vs. the other one. Is there any evidence for that?
