提出了一种基于感知模型的声辐射系统音质评价方法。采用此模型可应用Moore提出的参数以测试其是否适用于间接辐射扬声器的音质评价。对3种压缩式驱动器进行了测试,并且记录了它们在各种测试信号以及各种输入电压条件下的测试结果。基于上述实验结果,从不同的角度提出了解决该问题的方法:(a)考虑经典的音质评价参数,如粗糙度、尖锐度和音调;(b)应用由Moore建议的从感知模型获取的参数。此外,还进行了一项针对25人的心理声学实验,尽管实验结果只是初步的并极大依赖于参考信号,但仍然能够表明其与Rnonlin值的良好相关性。
A sound quality evaluation method of acoustic radiation system based on perceptual model is proposed. Using this model, Moore’s proposed parameters can be used to test their suitability for the sound quality evaluation of indirect radiating loudspeakers. Three compression drivers were tested and their test results recorded under various test signals and various input voltages. Based on the above experimental results, a solution to this problem is proposed from different perspectives: (a) Considering classical sound quality evaluation parameters such as roughness, sharpness and pitch; (b) Applying the parameters proposed by Moore to obtain from the perceptual model . In addition, a psychoacoustic experiment was conducted for 25 people, and although the experimental results were preliminary and strongly dependent on the reference signal, they still showed good correlation with the Rnonlin value.
