摘要：

We experimentally investigate the existence of Bragg and hybridization gaps in 3D bubble phononic crystals. Soft-lithography techniques allow us to tune the lattice constant, so that we can highlight the interactions between the two types of gaps. We show that a layered model provides a simple physical picture of the phenomenon.
