Researching sounds generated during the second lining pounding process

Abstract

Japanese calligraphy and works of art, which are written and painted on paper and silk, are often lined with Japanese washi paper and strengthened from the reverse side. They are then treated with various binding methods based on the purpose of the item and how it is intended to be viewed. The hanging scroll, which is a perfect example of a binding format, is only displayed when it is meant to be viewed and is hung on an alcove or beam. When it is finished being used, it is rolled up tightly from the bottom and stored in a box. In order to repeatedly roll up and open a hanging scroll smoothly, the hanging scroll is lined with several layers of Japanese washi paper, which are pasted onto the reverse side of the scroll. A paste with a low adhesive strength which has been further diluted is used to prevent the adhesive from hardening after it has dried. The joined surfaces are then pounded with a brush to enhance the adhesion. The level of expertise of this technique is determined by the sound that is generated when pounded using the traditional method. This research measures the sound generated when the joined surfaces are pounded by an expert and a non-expert with the purpose of evaluating the specific features of both sets of sounds.
