Abstract

The enclosure space is widespread in real life. However, from the angle on spatial hearing to study the variation of auditory perception caused by the changed structural parameters (such as volume, shape, etc) are very rare, particular in systematically research. In this paper, based on auditory scene simulation, the binaural auralization and sound field measurement techniques are used to obtain plenty of binaural signals in diverse enclosure spaces with different structural parameters. Subsequently, with the aid of the acoustic evaluation, the quantitative evaluation of spatial auditory perception change and its degree was carried out on the binaural signal. Major findings are summarized as follows: ①The change of the volume, shape, absorption coefficient of indoor walls of enclosure space can induce the variation of auditory perception of sound field. According to the degree of change (from obvious to not), the absorption coefficient of indoor walls, the shape, the volume is sorted. ②changing the receiving location could affect the variation on auditory perception caused by the volume and shape of an enclosure space.
