Hygen’s Principle and Single Slit Interference

I asked my friend the distinguished professor of Materials Science whether sound is influenced by the size and shape of a hole through which it passes. This is not quite the question of how air venting toward or away from a reed is affected by the size and shape of the opening through which it passes — he knows that the melodica is the application in which I’m interested. But he says that he believes the answer is Yes, and he gave me the following link to the physics in relation to light, saying that the same principles apply to sound. Physics is definitely not one of my strong suits.
