> I think you suffer from overpedantry and you are confusing electrical signal with just signal.
Tu quoque, ad hominem, and equivocation. "Signal" has multiple distinct meanings. You are conflating homonyms in equivocation, as well as attacking me personally while arguing, "you too!" Not all signal, by the definition you're conflating, is sound (such as semaphore, gesture, facial expression and even pheromonal response), and by the same vague definition, not all sound is signal (such as Berkeley's tree falling), not unless it is communication.
Context and semantics matter here. If we define sound as signal and vice versa, then there is no literal distinction between acoustic sound and analog signal, creating ambiguity and confusion. In the context of audio and sound, and from your own citation:
> in an analog audio signal, the instantaneous voltage of the signal varies continuously with the sound pressure... The term analog signal usually refers to electrical signals
A sound is also a a long, wide body of water that connects two other bodies of water, but it would be absurd and equivocating identical words of different meanings to claim that acoustic sound is also a body of water.
