Sound Transmission Loss of a Locally Resonant Metamaterial using the Hybrid Wave Based - Finite Element Unit Cell Method

This paper discusses the sound transmission loss of a locally resonant metamaterial, by application of the hybrid Wave Based - Finite Element unit cell method. Since damping has an important influence on the vibro-acoustic attenuation performance of these metamaterials, the impact of damping in resonator and host structure on the sound transmission loss is examined.status: publishe
