The sounds of the Korean temple bells, that are located in the various places, were recorded and classified into two groups according to the size of bells. The sound preference was investigated with the subjective listening test on the bells of each group. And the acoustic characteristics of the bells such as the frequency, amplitude, beat period, and 20 dB decay rate of the partials was analyzed. The correlation between the acoustic parameters and timbre preference were analyzed and the acoustic characteristics of highly preferred bell sound were presented.

Digilog Book lets users feel analog book and digital contents by combining each advantage of analog sensibility and digital sensation. This paper mentions about technical details for implementing an example of Digilog book: a temple bell experience system. Our system includes providing multisensory feedback to users, substituting fiducial marker with figure marker, presenting visual effect when a temple bell appearing on a 2D plane, pushing augmented buttons using bare fingers for observation of the bell, and lastly pointing a specific part of the bell for obtaining description on that part. The implemented temple bell experience system can motivate users to experience cultural heritages of our country as educational contents.

성덕대왕 신종을 비롯한 한국범종의 독특한 특성으로 맥놀이 현상을 들 수 있는데, 이것은 한국범종의 독창적인 형상과 재질에서 기인한다. 본 논문에서는 종의 형상과 재질을 달리하였을 때 종소리의 특성이 어떻게 달라지는가를 확인하고, 이로부터 가장 좋은 소리를 내는 종의 조건을 찾아보고자 한다. 이를 위해 주석 함량, 형상, 두께가 다른 열다섯 개의 모형종에 대해서 고유 주파수의 변화와 맥놀이 현상을 알아보았다. 그리고 한국범종과 외국종과의 차이점을 알아보기 위해, 일본종과 중국종의 대표적인 형상을 갖는 모형종을 한국범종을 모델로 한 모형종과 비교해 보았다. 또한, 울림통을 종의 아래에 설치하여, 울림통의 크기와 울림통과 종의 아래에 설치하여, 울림통의 크기와 울림통과 종 사이의 거리에 따른 종소리의 변화도 분석하였다.

At present, thirteen Buddhist bells of Unified Silla are known to the world: Six in Korea, five in Japan and two other bells, and three out of them are impossible to make out its original form. Therefore, we divided the form of Unified Silla Buddhist bells based on the ten other bells, and we tried out to prove the manufacturing technology by the comparison of the research material of Uncheon-dong bell and existing research materials of other bells, in other to find their linkage based on the alloy elemental composition. We divided Unified Silla Buddhist bell into two types: Type I has symmetric apsaras and regular patterns on its face and it was made in early Silla period; type II has asymmetric apsaras and irregular pattern arrangement and made in late Silla period. In particular, Uncheon-dong Buddhist bells is very similar to Komyoji[光明寺] temple bell from ninth century in Japan. It is peculiar that the apsaras on Uncheon-dong bell play vertical music instruments that are never seen in Unified Silla Buddhist bell. Most of Unified Silla Buddhist bell are compounded with Cu-Sn or Cu-Sn-Pb system. From eighth and ninth century, bells were cast with even composition of copper, tin and lead, and the bronze alloy ratio was similar to the record in Gogonggi[考工記], Jurye[周禮], a book from ancient China. Particularly, Uncheon-dong bell is in a rare case of Cu-Sn-Pb-As system. As had been rarely used in Unified Silla Buddhist bells, so we presented the relative research materials. As has the same nature as Pb. Because As easily volatilize at high temperature, it is hard to use. But it has its merit of solidity and durability. Pb enhances fluidity and thereby expresses the patterns more distinct; As makes the bell stronger. The result of lead isotope ratio could not exactly reveal a concrete producing center. However, over the analysis of our samples, hereby we suggest Uncheon-dong bell was made of materials from just one ore deposit.
