民族音乐厅堂响度优选试验

响度是厅堂音质评价的重要指标之一．为对民族音乐厅堂的响度进行优选，在消声室内录制民族音乐干信号，同时采用可听化技术产生厅堂脉冲响应，并将干信号和仿真的厅堂脉冲响应卷积．卷积结果最终用于主观听音评价．该实验通过比较仿真和实测的声学参数来验证仿真方法的可行性，与实测结果的对比表明，仿真方法具有较好的仿真精度．文中还在改进响度划分方法的基础上应用成对比较法对民乐演出厅堂的响度进行了优选，从而确定民族音乐的优选响度．

Experiments of Preferred Loudness of National Concert Hall

Loudness is an important parameter for the acoustic evaluation of concert ball. In order to predict the preferred loudness of national concert hall, some experiments were performed, in which the dry signal was recorded in an anechoic chamber, and, at the same time, the signal was convolved with the simulated impulse response of the national concert hall by using the auralization technology. The convolved results were then applied to the subjective acoustic evaluation. Moreover, a comparison between the simulated parameter and the measured one was carried out, by which good feasibility and high accuracy of the simulation were revealed. Finally, by adopting the paired-comparison method and the improved method of loudness division, the preferred loudness of national music hall was determined.
