A research has been undertaken in order to restore the original bell pavilion of King Song-Dok Bell. And the historical background and the acoustic characteristics of the King Song-Dok Bell were investigated. The proposed model of the bell pavilion which is supposed to fit with the King Song-Dok Bell was suggested on the acoustical reasons. Considering acoustic criteria of King Song-Dok Bell, the following models for bell pavilion of King Song-Dok Bell are suggested as follows; 1) bell pavilion has the concave cavity on the ground for resonance of sound. 2) according to the natural sound frequency ranges from 64Hz to 168Hz, it's considered that the bell pavilion is constructed with many rectangular lumber and timbers as column, beam rather than 2-dimensional panel. 3) board panels could be placed between the lintel and a middle molding of a wall in order to reduce the effects of sunlights and sea wind. 4) the roof structure shows the form of bell pavilion which could magnify the ground waves. 5) a rectangular or a square structure which has an odd-Kan are proposed. 6) concerning the roof structure, a form of Pal-Jak is supposed to nearly close to the original form.
