I think this just repeats the original ambiguity of the question, by using the word “sound” in a context where the common meaning (air vibrations perceived by an agent) is only partly applicable. It’s still a question of definition, not of understanding what actually happens.
But the way to resolve definitional questions is to come up with definitions that make it easier to find general rules about what happens. This illustrates one way one can do that, by picking edge-cases so they scale nicely with rules that occur in normal cases. (Another example would be 1 as not a prime number.)
My recommended way to resolve (aka disambiguate) definitional questions is “use more words”. Common understandings can be short, but unusual contexts require more signals to communicate.
