It is a common belief among room acousticians that reverberation later than 80ms after the direct sound does not contribute to auditory spaciousness. However there is no definitive proof for this opinion. In this paper, two psychoacoustical experiments were performed. The first one compared the degree of spaciousness as caused by reverberation with the degree of spaciousness as caused by early reflections. The second one investigated whether spaciousness as caused by reverberation is suppressed by early reflections. The results indicated that the contribution of reverberation to spaciousness is the same as that of early reflections.
