  • There have been always some difficulties in target setting and conditioning of acoustic performances of the Korean traditional music hall due mainly to the lack of the information on the sound radiation characteristics of Korean musical sources. In this study, the radiation characteristics of four typical Korean traditional musical sources were investigated in precision and their usage was demonstrated: The selected musical sources were Gayageum (string), Daegeum (woodwind), Jango (drum), and Pansori Chang (vocal performance). Each sound source was located at the center of a semi-anechoic chamber and the directivity was determined by the measured sound pressure levels in every 10° angular position, for both vertical and horizontal directions. The directivity pattern of Gayageum varies from a uniform to a complex pattern having many side lobes with the increase of frequency. The main radiation of Daegeum is toward the upward direction. The directivity pattern of Jango is clearly a side-oriented one and the left direction intensity is sharper than its right side at low frequencies. For the Chang, the directivity pattern change from a uniform pattern to a frontally directed one as the frequency goes high. Measured directional and spectral characteristics of traditional Korean music sources were implemented into the computation of architectural acoustic measures for the Busan National Korean Traditional Music Hall which is under construction. Parameters such as RT, SPL, C80, IE, STI were calculated at two receiver positions by using a ray tracing technique. Significant differences in the acoustic measures at receiver positions were observed between the results in using the omni-directional source and the directional one. 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.

  • 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.

  • Have been so many times to attempt to enhance the usefulness and convenience about using the sample sound of Korean traditional instruments. Was determined additionally VST plug-sequencer and sample libraries, a variety of methodologies, but did not lead to practical use. This study is a work in order to increase the usability of sample sound of Korean instruments. We have developed sound samples of Haegeum and Daegeum based on most widely used Kontakt sampler. Have aimed to develop sound samples for accompanying with useful function supported by Kontakt sampler helping various musical expressions.

  • The present study aims to investigate the design standard for acoustic criteria of Korean traditional music which could be used for the design of Korean traditional music halls. In order to do this, subjective listening tests were undertaken to musicians using auralized sounds which were convolved with the impulse response of traditional instruments recorded in an anechoic chamber. 94 pairs of sound were made which have different value of acoustic parameters including RT, BR, Brilliance, G, C80, ITDG, IACC. A paired comparison method(PCM) was used to analyze the results from the subjective listening tests. The results show that the preference of acoustic criteria for the Korean traditional music is far different from those of western music. As a result, specific range of acoustic criteria were suggested for the appropriate acoustic conditions of Korean traditional music. Also, a guideline of the acoustic design of halls for performing the Korean traditional music was suggested which could be used as a basic reference in the future works.

  • 국악전용 공연장으로 지어진 국립국악 소극장의 음향 특성을 실내 음선도, 암소음, 잔향시간 및 음압분포에 의해 분석.평가하였다. 연구결과 무대 앞부분과 객석모서리에서 음선경로차가 17m 이상으로 나타나 회주공조현상의 발생이 예측되며 남부순환도로와 인접하여 소극장내에 높은 암소음이 측정되었다. 잔향시간의 측정결과 과다한 실내 흡음력으로 인해 공석시에 계획값 보다 0.8초 정도가 짧으며 이는 관객입장시 더욱 악화될 것이 예측되어 1석당 실용적을 증가와 실내 흡음력을 가능한 줄일 필요가 있다. 음압레벨은 음악당 전 객석에서 고른 음압분포가 보이고 있으나 무대 음원에서 객석전열 사이에 초기 음압감쇠가 크게 나타나 무대주변의 음압 보강이 요구된다.

  • In this paper, we present a software for placing instruments on stage based on the acoustic properties of the concert hall. In order to simulate the changes in sound depending on the positions of the instruments, we incorporated the idea of location-based reverberation effect which can be realized through the convolution of instrument sounds with the impulse responses from the respective instrument positions. And we developed a software with a real-time convolution engine which enables the user to conveniently simulate the resulting sound of various instrument placements. The software was tested with the impulse response data measured at two concert halls of the National Center for Korean Traditional Performing Arts and Korean traditional instrument sounds. Results of these experiments show that simulated reverberation effects properly represent the spatial placement of instruments on stage.

  • In this paper, we proactively looked at the structure and characteristics of each instrument in order to compare and analyze the sound colors of the western violin, chinese erhu and korean haegeum, which are representative bow string instruments. Also, many performers have simply been unable to fully explain how the violin is rich in pitch and the haegeum has a unique tone. Also, many performers thinks that violin sounds rich just because it has many overtones and have been unable to fully explain how haegeum makes unique tone. While previous research data show that most instruments are studied and published by analyzing their own frequencies or related cases of acoustic studies, this study provides a visual look how the harmonics composition, which determines musical instruments' timbres, consists of and suggests data specifically by analyzing each sound pressure of integer multiple overtones so that the structure of instruments' unique timbre can be understood. Based on this, we hope that it will be of considerable help to the development of virtual musical instruments of korean traditional instruments, which are relatively small compared to western virtual instruments, by reproducing instrument sounds through the synthesizers in the future.

  • The characteristics of the vibrato of danso, one of the wind instruments in Korean traditional music, have not been studied much. In this study, the characteristics of the vibrato of danso were analyzed using monotones and musical performances. In particular, intonation, vibrato rate, and vibrato extent were measured as a function of time, and their average values for each vibrato tone were also calculated. The results for vibrato rate showed that the vibrato tended to start slowly and then increase very quickly and significantly and the average values for each tone were observed to have a very wide range, which shows that the characteristics of the vibrato of danso are different from those in Western music. In addition, monotones and musical performances showed some different results in vibrato rate and vibrato extent. There have not been many studies that have quantified the intonation, vibrato rate, and vibrato extent in Korean traditional musical instruments, and this is especially true in the case of danso. The results in this study can be used as basic data on danso vibrato. For example, they can be used as reference materials in education, danso virtual instruments, and danso applications.
