In this work, we explore the use of acoustic metamaterials in delivering spatially significant acoustic experiences. In particular, we discuss a user study run in a space where a dedicated composition is played through a metamaterial "prism". Results show users perceive sound to be louder in the direction determined by the metamaterial, depending on its frequency. This demonstrates how an acoustic metamaterial prism, in combination with an electronic composer, may be used to deliver different sound messages to different parts of an audience, even with a single speaker. We underpin our conclusions with user observations and heuristic considerations on possible application scenarios.
