Acoustic Transfer Function of the Anjok: A Bridge of the Korean Traditional String Instruments
Hyun-Woo Koh, Jung Uk Noh, Sangha Park, Koeng-Mo Sung · 2007
The Anjok is a common name of the bridges of several Korean traditional string instruments, such as the Gayageum, the Geomungo and the Ajaeng. It, like the bridges of the violin family, plays a role in boundary of string and supports tension of string. Also, as compared with the bridges of the violin family, the Anjok has some unique characteristics. In the case of the violin family, a bridge supports all strings and is located on fixed place. However, one Anjok supports only one string. And it can be moved along the string in order to tune the string. We once studied on the acoustic characteristics of the Gayageum Anjok in the year 2006. We have measured some impulse responses of the Anjok on two kinds of boundary conditions, one was a rigid boundary (stone plate) and the other was Gayageum body. In this paper, we measured some impulse response transfer functions of the Gayageum Anjoks again with our new and more precise measurement equipments (B&K PULSE with B&K Force transducer and Accelerometer), and could acquire more significant results.
