Abstract
Characteristics of metamaterials are mainly used to obtain desired acoustic characteristics by artificially changing spacings or thicknesses. In particular, in the field of acoustics, in consideration of the characteristics of the equalizer using metamaterials, it is possible to make acoustic changes in consideration of various characteristics by emphasizing or shifting specific frequencies. Since these characteristics can be applied in various ways without changing the characteristics of the existing room, it is possible to create free acoustic spaces in an auditorium or open space that cannot give spatial changes. Because the acoustic characteristics use the characteristics of the frequency amount, the fact that the existing electro-acoustic can be used is very beneficial. This study introduces an acoustic metamaterial that can be changed with various characteristics by designing these metamaterials.

Keywords
