First of all, I joined physics.SE only for the purpose of asking this question on Meta.
I asked a couple of questions regarding acoustic in sound.SE. For example What are combs, nodes and how to calculate the nodes and comb frequencies at a given position? or to a lesser extent How works perforated acoustic wood panels?
Those questions could belong to different SE sites. I originally chose sound.SE because I was interested in an answer from an audio engineer's point of view. However, those questions didn't get much attention.
Is there a procedure to raise the attention of the physics.SE contributors to questions asked on a different SE site? Or should I request the migration of the questions to physics.SE?
I'm aware that asking that on meta will de facto bring those questions to the attention of users active here. So in a sense, this question contains its own solution--which finally seems quite adequate for a "meta-question" ;)
