阮是中国传统的弹弦乐器之一.但迄今为止,对其声功率一直未进行科学的测定.文中在一混响室内根据有关ISO及GB标准,对阮的声功率进行了首次测定.由两位资深乐师在混响室内分别演奏各自的乐器,围绕乐师和乐器布置四通道测试设备,对阮所辐射的声功率和动态范围进行测定.文中所介绍的测试方法对其它乐器声功率的测试具有借鉴意义.文中还首次公布了阮的声功率测试结果.民族乐器声功率的测试对于民族音乐厅堂的音质研究具有重要意义.
Nguyen is one of the traditional Chinese string instruments, but so far its acoustic power has not been measured in a scientific way.The first measurement of the acoustic power of Nguyen was carried out in a reverberation room according to the relevant ISO and GB standards. The senior musicians played their respective musical instruments in the reverberation chamber and arranged four-channel test equipment around the musician and the instrument to measure the sound power and dynamic range radiated by Nguyen.The testing methods introduced in this paper have the following functions The paper also announces the result of Nguyen sound power test for the first time.The test of sound power of national musical instrument is of great significance to the study of the sound quality of the national concert hall.
