Strong, exciting, and engaging sound is perceived in the best concert halls. Here, it is shown that wideband early reflections that preserve the temporal envelope of sound contribute to the clear and open acoustics with strong bass. Such reflections are fused with the direct sound due to the precedence effect. In contrast, reflections that distort the temporal envelope render the sound weak and muddy because they partially break down the precedence. The presented findings are based on the earlier psychoacoustics research, and confirmed by a perceptual evaluation with six simulated concert halls that have same monaural room acoustical parameter values according to ISO3382-1.
在最好的音乐厅中，人们可以感受到强烈、激动人心且引人入胜的声音。在这里，研究表明，保持声音时域包络的宽带早期反射有助于产生具有强烈低音的清晰开阔的声学效果。由于前导效应，这些反射与直达声融合在一起。相比之下，那些破坏时域包络的反射会使声音变得微弱和浑浊，因为它们部分破坏了前导效应。这些发现是基于早期的心理声学研究，并通过对六个模拟音乐厅的感知评估得到了验证，这些模拟音乐厅根据 ISO3382-1 具有相同的单声道房间声学参数值。
