Psychoacoustic investigations have confirmed the known high correlation of auditory spaciousness and preference in concert-hall types of sound fields. Further, they have provided exploratory results which gave rise to the following interpretations: Auditory spaciousness is a multidimensional perceptual attribute, predominantly caused by early lateral reflections. Low-frequency reverberation may also contribute slightly, but is sensitive with respect to individual taste. All spectral components of early lateral reflections contribute to spaciousness. Spectral restriction of the reflections leads to less favorable judgments. Early lateral reflections which do not contain spectral components above about 3 kHz mainly create image expansion in the front-back direction, thus adding to the sense of envelopment of the listener. If components above about 3 kHz are present, image broadening is prominent. By means of a model of binaural signal processing which takes interaural arrival-time differences as well as interaural level differences into account, a quasiobjective measure of auditory spaciousness can be derived.
心理声学研究已经证实，在音乐厅类型的声场中，听觉空间感与偏好之间存在着已知的高度相关性。此外，这些研究还提供了一些探索性结果，引发了以下解释：听觉空间感是一种多维感知属性，主要由早期侧向反射引起。低频混响可能也有轻微贡献，但对个人喜好较为敏感。早期侧向反射的所有频谱成分都对空间感有贡献。反射的频谱限制会导致评价较低。不包含高于约3kHz频谱成分的早期侧向反射主要在前后方向上产生图像扩展，从而增强了听众的包围感。如果存在高于约3kHz的成分，则图像展宽较为显著。通过一个考虑双耳到达时间差以及双耳声级差的双耳信号处理模型，可以得出听觉空间感的准客观度量。
