| 本文对近年来音乐厅音质设计中若干问题的进展作一述评。(1)在已建立的众多独立音质参量基础上,如何作出大厅综合评价,就需要考虑到它们的互动性和贡献权,方法学将成为关键。(2)空间感已确认由声源视在展宽度ASW和听青环绕感LEV组成,对于影响两者的诸多复杂因素有了较深入研究,这些声场中的细节又将如何与大厅设计相联系亦备受关注。(3)听众及座椅吸声这个老问题有了新的研究成果,对于空、满场的声学关系已积累了更多资料,使大厅音质的估算更为精确可靠。(4)常说扩散对大厅音质很重要,但其主观效应仍然处于玄虚状态,一些新的主观试听实验结果还不足以说明问题。 |
| 英文摘要: |
| This paper is an overview of the progress made in the field of acoustical design of concert halls. (1) It has been widely recognized that at least five or six physical parameters are used for specifying and evaluating sound field in concert halls. They are developed independently, and all of them contribute to the overall subjective rating of a hall. Therefore, a combined effect of all parameters with different weighting for various performances should be considered. Methodology becomes very important in weighting factor determination. (2) The importance of spatial impression (source broadening and listener’s envelopment) to overall concert hall rating tenas to be broadly accepted. Researchers are now striving to better understand the importance of the details of sound field on perceived spatial impression and how these sound field details are related to hall design. (3) As the audience arid seats compose the main absorption in a hall, recent investigations armed with concrete data make the estimation of hall acoustics more accurate. (4) It is generally believed that diffusion in a concert hall is important but there is little published evidence to support this conclusion. Some tests on subjective effects of scattering in rooms were conducted recently. However, it is still quite insufficient to give a more complete view of this subject. |
