摘要
在音乐厅中,空间印象被认为是由视在声源宽度(ASW)以及听者包围感(LEV)所描述的音质.许多研究者曾对此能影响观众厅空间印象的声学参量得出过一些结论.然而,LEV与声压级的关系尚未充分被认识.因此,文中对SPL和IACC等声学参量从频域和时域等方面加以研究,并在新的Sejong室内乐厅(476座)采用嗓音作为声源进行主观评价,探讨听者的判断与受早、后期声能影响的客观参量之间的关系,并确定能产生听者包围感的最低声强(G)值.
Spatial impression has been regarded as the item ascribable to the quality of apparent source width （ASW） and listener envelopment （LEV） in concert halls. Many researches have been conducted on the acoustical parameters which affect the spatial impression in auditofia. However, the LEV in relation to sound pressure level has not been fully recognized. Therefore, in this study, the spectral and temporal aspects of the acoustical parameters such as SPL and IACC were investigated, and subjective evaluation was conducted on the vocal sources in the new Sejong Chamber Hall （476 seats）. The relationship between the listeners＇ judgment and the objective parameters influenced by the early and late sound energy was sought to determine the minimum level of sound strength （G） for listener envelopment.
