Perhaps in 4d most life would be deaf as there wouldn't be enough of a benefit from detecting sound to favor hearing.

I think it depends on how strong is the damping effect of the echoes, like when you have an oscillating L-C circuit, if its quality factor is low, then only 2 or 3 periods will happen, so I don't think sound communications are impossible, but surely different than in 3D.

That's an interesting thought. What if the sound is transmitted through a highly non-elastic medium that has a high damping factor? That could offset the effect of the echoes. But of course, it will also limit the range of sound and some muffling will happen regardless, so crisp sound like we have in 3D will probably be impossible.
