I will gladly die on this hill.
Obviously! Well done. Your definition is delusional and at odds with science and common language use, yet you won't back down. That takes commitment. It also has me questioning whether you believe in light outside human perception (since it's also measured as a wave). You are the embodiment of this fun thread! And I genuinely enjoy thinking about both positions.
But I think I'll stick with the Wikipedia and dictionary editors, and the likes of Britannica which states:
Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective definition of sound is also possible, as that which is perceived by the ear, but such a definition is not particularly illuminating and is unduly restrictive, for it is useful to speak of sounds that cannot be heard by the human ear, such as those that are produced by dog whistles or by sonar equipment.
