현재 국악기의 음향특성에 대한 상세 정보가 매우 부족하며, 이러한 점보의 부재는 국악당의 설계에 있어서 최적의 음향을 전달하는 공간을 형성하지 못하게 하는 한 원인이 되고 있다. 따라서, 대표적인 각종 국악기의 음향특성을 측정하고 분류한 후 데이터베이스를 구축하면, (1) 향후의 국악 및 국악기 개발에 대한 기초연구로서 활용들 수 있으며, (2) 국악전용 연주장의 설계에 있어서 입력 데이터로 요긴하게 활용될 수 있으리라 판단된다. 본 연구는 국악기의 음향방사특성을 조사하기 위한 제 2 단계의 연구로서, 기존의 연구 [1] 에 새로운 국악기 8 종을 추가하였다. 선정된 국악기는 현악기중에서 거문고와 해금, 관악기 중에서 피리와 태평소, 타악기 중 북과 꽹가리, 징 및 남성창으로, 원거리 (far-field) 음향 방사 특성을 조사하였다.

There have been always some difficulties in target setting and conditioning of acoustic performances or the Korean traditional music hall due mainly to the lack of the information on the sound radiation characteristics of Korean musical sources. As the 2nd experiment succeeding the previous study[1], the radiation characteristics of eight typical Korean traditional musical sources were investigated if precision. The selected musical sources were Geomungo, Haegeum (string), Piri, Taepyeongso (woodwind), Buk, Kwaengguari, Jing (drum), and male Pansori Chang (vocal Performance). The results show that the directivity pattern of each instrument is different and has their own directivity characteristics. Measured directional and spectral characteristics of traditional Korean music sources were implemented into the computation of architectural acoustic measures. Significant differences in the acoustic measures at receiver positions were observed between the results in using the omni-directional source and the directional one. In order to investigate the acoustical characteristics of the instruments depending on the spatial variation four different shapes of halls were introduced including rectangular, fan. horse-shoe and geometrical shapes. Room acoustical parameters such as RT, SPL, C80, LF, STI were calculated at each type or hall. As the results, It was found that the rectangular hall has the most high clarity. lateral energy and STI values among low shapes of halls. It is thought that the suggested source data and design method can be used as a basic reference in the future acoustic design of performance halls for the Korean traditional music.

가상현실은 시·공간을 초월하는 경험이 가능하며 아이들의 몰입감과 학습효과를 높일 수 있어 교육 도구로서의 가치를 인정받고 있다. 정부는 VR 기기를 전국의 초등학교에 보급하고 있지만, 양질의 교육용 실감형 콘텐츠는 부족한 상황이다. 따라서, 본 논문에서는 가상현실 기술을 활용한 국악기 연주 체험 프로그램을 제안하였다. Unity의 물리 엔진과 Oculus의 햅틱 기능을 이용하여 전통 국악기 중 편경을 실감 나게 연주할 수 있도록 가상환경을 구현하였다. 리듬 게임 형식을 적용하여 아이들의 흥미 또한 유발하였다. 이 프로그램을 통해 국악기를 직접 연주하며 해당 국악기에 대한 지식을 자연스럽게 습득할 수 있을 것이라 기대한다.

Since 1964, research and improvement projects on Gugak instruments have been carried out to modernize, standardize, and scientificize them, but their inherent problems of Gugak instruments have failed to produce significant results. It seems that one of the main reasons for this is that the study of instrumental acoustics on Korean traditional instruments was not preceded. In Gugak orchestra, Sogeum used in concertos and solo music is a musical instrument that plays the similar role in Western orchestras due to its clear tone and high sound range. In this paper, the sound colors of Sogeum and flute, which sound similar, were analyzed through the their harmonics distribution and sound structures of the instruments. This showed that the overall tone was richer and softer than Sogeum, and that the tones of the two instruments sounded similar due to the similar composition of harmonics. In the future, it is hoped that musical instrument acoustical researches on various Gugak instruments will continue to help popularize and globalize Gugak instruments.

This study recorded the sound of Korean traditional musical instruments by considering the radiation characteristics of traditional Korean musical instruments and setting the diverse mounting angle and distance of microphone. By following recorded results, the study analyzes the optimum position of microphone and the characteristic of timbre through frequency range spectrum and repeated listening. This experiment of study is for technique of close microphone which is used in popular music, therefore it is recorded in the popular music recording studio. The study also suggests the optimum position for the microphone to record, and explains the difference of timbre at different position. The result of study will suggest the best technique of Close Microphone Techniques for Korean Traditional Musical Instruments not only to accurately express the beautiful and unique sound of traditional Korean musical instruments but also to obtain diverse timbre.

Classification method used in this paper is applied for the first time to Korean traditional music. Among the frequency distribution vectors, average peak value is suggested and proved effective comparing to previous classification success rate. Mean, variance, spectral centroid, average peak value and ZCR are used to classify Korean traditional musical instruments. To achieve Korean traditional instruments automatic classification, Spectral analysis is used. For the spectral domain, Various functions are introduced to extract features from the data files. k-NN classification algorithm is applied to experiments. Taegum, gayagum and violin are classified in accuracy of 94.44% which is higher than previous success rate 87%.

In the field of music, various AI composition methods using machine learning have recently been attempted. However, most of this research has been centered on Western music, and little research has been done on Korean traditional music. Therefore, in this paper, we will create a data set of Korean traditional music, create a melody using three algorithms based on the data set, and compare the results. Three models were selected based on the similarity between language and music, LSTM, Music Transformer and Self Attention. Using each of the three models, a melody generator was modeled and trained to generate melodies. As a result of user evaluation, the Self Attention method showed higher preference than the other methods. Data set is very important in AI composition. For this, a Korean traditional music data set was created, and AI composition was attempted with various algorithms, and this is expected to be helpful in future research on AI composition for Korean traditional music.
