1. A sound insulation panel comprising:
a patterned plate comprising an edge plate and a separation plate extending into an inner region of the edge plate and dividing the inner region into a first elastic region and a second elastic region; and
an elastic plate protruding from the patterned plate to be stepped with respect to the patterned plate and comprising a first elastic plate disposed in the first elastic region and a second elastic plate disposed in the second elastic region, the elastic plate blocking an air flow path and converting airborne sound waves into elastic waves,
wherein the first elastic plate and the second elastic plate are displaced in opposite directions at a resonant frequency of the sound insulation panel,
wherein the patterned plate further comprises a protruding plate protruding from the edge plate or the separation plate, having one end connected to the edge plate or the separation plate and another end connected to the first elastic plate or the second elastic plate, and
wherein the protruding plate is corrugated to be variable in height.
