阮是中国传统弹拨乐器中最受欢迎的乐器之一。但它的声功率级从未被仔细测量过。本文根据ISO标准和中国国家标准，首次在混响室中对阮氏的声功率进行了测量。两位合格的音乐家在混响室的中央用自己的乐器表演。用四声道声学测量装置测量了中段和大段的辐射声能和动态范围。通过平均得到了典型的声功率值，并给出了计算结果。该方法对其他乐器的声功率测量也有一定的参考价值。民族乐器辐射声功率的测量为民族音乐厅的声学研究奠定了基础。
Ruan is one of the most popular Chinese traditional plucked stringed instruments. But its sound power level has never been carefully measured. In this paper, the sound power measurements of Ruan were performed for the first time in a reverberation chamber according to ISO standard and Chinese national standard. Two qualified musicians performed on their own instruments in the center of the reverberation chamber. The radiated sound energy and the dynamic ranges of the middle and big Ruan were investigated by four channel acoustic measuring equipments. Typical sound power values were obtained through averaging and the results were reported in this paper. The method discussed here is valuable for the sound power measurements of other musical instruments. The measurement of the sound powers radiated by national musical instruments lays foundations for the investigation into the acoustics of national music halls.
