摘要:
封闭空间在现实生活中广泛存在。然而,有关因封闭空间的结构参数(如容积、形状等)改变引发室内声场听觉感知变化性的研究则很少见,尤其缺乏系统深入的量化研究。为此,首先以双耳可听化技术配合室内声场测量,通过对听觉场景的模拟,获取了不同结构参数条件下的封闭空间室内双耳信号若干。随后,借助听音实验,对上述双耳信号开展了空间听觉感知变化性及其变化程度的定量评价研究。研究发现:①封闭空间容积、形状、壁面吸声系数的改变均能够引发声场听感变化,按照其变化明显程度(从大到小)排序为:壁面吸声系数、形状、容积;②变换听音位置,能够在一定程度上影响因空间容积与形状改变导致的室内声场听感变化性。

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.
