Haha, in 2500D, would you be able to hear
anything at all?? You'd have to put your ear next to your neighbour's mouth in order to pick up the sound before it completely dissipates!
Because of the same phenomenon, though, the higher up the dimensions you go, the more likely your world will be a very dark one. I think I did a short derivation of this before, somewhere on this forum, that making the (very big!) assumption that you live on an n-spherical planet in n dimensions, for large n the vast majority of the surface of the planet would be perpendicular to any single light source, like a nearby star. So only a tiny fraction of the planet's surface would be illuminated, (and conversely only a tiny fraction would be completely dark, i.e., opposite the single light source), whereas most of the planet would be in perpetual dusk. Seems to be a pretty miserable way to live.
Of course, all of this is probably moot because AFAIK, stable orbits only exist in 3D and below, so if life exists in a higher dimensional space at all, it must be live in a completely alien environment than our poor 3D brains can imagine. And it must also take on completely foreign forms too, because in 4D (and I assume higher dimensions too, though I don't have proof of that) the Schroedinger equation for the hydrogen atom has no local minima besides r=0, meaning electron orbitals cannot exist and atoms as we know them would instantly collapse and would not form the basis of matter and chemistry as we know them. So if matter exists in 4D and above at all, it must be of a form that's so foreign that it would resemble nothing like how we perceive our world.
