The standards for design and evaluation of Chinese concert halls have followed that of western music and western concert halls all the time. In recent years, studies on the sound characteristics of Chinese traditional musical instruments have been conducted. Wind instrument is an important type of traditional national musical instruments of China. The Chinese flute (Di) is the most representative one among them, the oldest type with a history almost 9000 years, and it is still one of the most widely used instruments now. So the study of Qudi (a main kind of Di) can be seen as a representative research work of traditional national wind instruments of China. The measurement presents the sound power level, dynamic range and frequency characteristics of Qudi when single notes, a music scale and a typical melody are performed at various dynamics. This is the first time a research measures the sound power of Qudi by multi-channel real-time analysis method in a reverberation room according to ISO and Chinese national standards. It shows that, Qudi has higher sound power level and a limited dynamic range when compared with Chinese traditional stringed and plucked instruments. The main energy radiation of Qudi is in the alto (middle) range and soprano (high) range. Here, we use sound power level of the music scale performed at forte dynamic as the representative value of Qudi’s SWL, and it is 96.2dB.
