Sound quality improvement using digital filter in carbon body renovate haegeum

Abstract

Since, 2000, the trend of Korean traditional music and Korean traditional musical instruments is consumption of musical instruments and music is becoming more popular among the public. And there is a growing interest in traditional music and more specific curiosity about traditional musical instruments. However, the systematic research on Korean traditional musical instrument production has not yet achieved high performance, furthermore, the production of musical instruments is not out of the limit of craft technology. Because it is a 'traditional musical instrument', it is produced in a traditional way, mainly using wood which is a material transferred from the past. Although, it may achieve the goal of preserving tradition and conveying the sound of tradition, it is difficult to create a good instrument that satisfies popular popularity and demand for traditional instruments without changing materials and method. Wood is easy to obtain from nature has good handling characteristics but is not suitable for mass production. In addition, traditional instruments are difficult to learn and play in terms of how to handle them and how to manage them. Traditional Korean musical instruments haegum has been produced by musical instrument master makers who have maintained the classical method of using traditional and wood materials. For that reason, the amount of instruments supplied is so, small that it does not meet the demand to learn and play haegeum. And even if you try to play the traditional haegeum for a hobby or education, it is hard to play and hard to manage compared to the effort of the person to learn. In this study, we compare the sound of traditional haegeum and carbon body renovate haegeum which are produced by master and 3D printing each. The improvement of the renovate haegeum was confirmed and the sound source was analyzed. We also introduce how to enhance the sound quality by adding a digital filter. © 2018, Medwell Journals.
