Abstract
A method of shielding acoustic wave, which is capable of completely shielding sound while reducing consumption of a shielding material is provided. The method of shielding acoustic wave, includes covering an object to be shielded with a first shielding material so that a lower portion of the object to be shielded is opened, covering an upper portion of the first shielding material by using a second shielding material which is an acoustic wave meta material having same absolute value but negative sign in density and bulk modulus comparing to the first shielding material, and covering the second shielding material with a third shielding material.
