Abstract

Abstract:

Yangqin is one of the most popular Chinese traditional instruments with a long history. Although it is an important regular musical instrument in Chinese music ensemble , its sound power level has not yet been determined. In this paper , the sound power level measurement of Y;αngqin was performed in a reverberation chamber , and the sound output and the corresponding dynamic range were obtained by means of multi -channel measurement. The typical sound power levels of ytαngqin were then obtained when performing single notes , music scales and a piece of folk music under pp , mp , f and ff dynamics , respectively. It is suggested that the forte sound power and its spectrum when performing a music scale under f dynamic can be chosen to represent the sound power of Yangqin, and that the sound power dynamic range of ytαngqin can be specified by the range when performing a music scale under pp and ff dynamics.

Key words: Yangqin, sound power level, measurement, national musical instrument
