Acoustic metamaterials are artificial structures made of subwavelength units with novel properties in comparison with the acoustic materials found in nature. For example acoustic metamaterials with anisotropic mass density have been proposed and employed to design acoustic cloaks. I will review our homogenization theory to obtain the effective parameters of acoustic metamaterials based on two-dimensional arrays of solid cylinders. I will also report different engineering procedures for obtaining anisotropic metamaterials and their characterization in the sonic domain. Though the construction of acoustic cloaks still remains a challenge an acoustic cloak for airborne sound based on inverse design will be presented. Finally I will introduce a new type of crystalline structures called Radial Sonic Crystals which are only realizable with specific anisotropic metamaterials.
