Abstract
We address a maximally structured case of the question, “Can you hear your location on a manifold,” posed by Wyman and Xi [Can you hear your location on a manifold?, https://arxiv.org/abs/2304.04659, 2023] for dimension 2 2 . In short, we show that if a compact surface without a boundary sounds the same at every point, then the surface has a transitive action by the isometry group. In the process, we show that you can hear your location on Klein bottles and that you can hear the lengths and multiplicities of looping geodesics on compact hyperbolic quotients.
