本文介绍了六个新的实验，涉及主观评价的听众的听觉，LEV，和表观源宽度，ASW，模拟声场。以前的工作已经确定了LEV和ASW作为音乐霍尔斯空间印象的主要组成部分，并表明ASW主要受早期横向反射水平和LEV的影响。在本文中的新结果表明，LEV可以导致从非横向晚到的声音，并证明了冲突的影响，早期和晚期到达的横向声音对ASW和LEV时，都存在，将发生在真实的霍尔斯。虽然可以仅使用LEV或ASW创建模拟声场，但在典型的音乐霍尔斯中，早到和晚到的横向声音之间的平衡将决定LEV和ASW的相对重要性。LEV和ASW被认为是当声场的关键组件是突出的相对于其他组件。新的主观研究的结果被用来估计预期的ASW和LEV在16个霍尔斯。在这些霍尔斯里，LEV被预测为空间印象的更强的组成部分。
This paper describes six new experiments involving subjective ratings of the listener envelopment, LEV, and the apparent source width, ASW, of simulated sound fields. Previous work has identified LEV and ASW as the principal components of spatial impression in concert halls and has shown that ASW is primarily influenced by the level of early lateral reflections and LEV by late-arriving lateral reflections. The new results in this paper show that LEV can result from nonlateral late-arriving sounds and demonstrate the conflicting effects of early- and late-arriving lateral sound on ASW and LEV when both are present, as would occur in real halls. While it is possible to create simulated sound fields with only either LEV or ASW, in typical concert halls, the balance between early- and late-arriving lateral sound will determine the relative importance of LEV and ASW. LEV and ASW are shown to be perceived when the critical components of the sound field are salient relative to other components. The results of the new subjective studies were used to estimate expected ASW and LEV in 16 halls. In these halls LEV is predicted to be the stronger component of spatial impression.
