ACOUSTICAL DESIGN OF HUANGPU COLISEUM IN SHANGHAI

Huangpu Coliseum is a multipurpose hall of medium size with a seating capacity of 3808.Aneffective and aesthetical design of the ceiling bas proved to be successful both in acoustics and in archi-tecture.A semicentral sound system was designed and proved to be satisfactory for the purpose ofboth gathering and performance.

EFFECT OF RESILIENT CONNECTION ON SOUND TRANSMISSION LOSS OF METAL STUD DOUBLE PANEL PARTITIONS

Existing techniques for predicting sound TL of double panel partitions are usually based onthe assumption that the mechanical connection of the stud is a rigid sound bridge,but they pro-vide unrealistic estimates of the TL in the case of metal stud partitions,of which the TL is sig-nificantly improved at mid and higher frequency regions owing to the lateral resilient effect of thestud itself.A modified expression for prediciting the TL of metal Stud partitions is thus given inthis paper,which is in good agreement with experimental results.In addition,the effects of addi-tional resilient pad strips on both sides of the stud are discussed.It is shown that even for sucha complex structure the TL can also be determined approximately by means of a set of simpleexpressions.     

向宁编委荣获美国赛宾奖章

<正>《声学学报》、《Chinese Journal of Acoustics》两刊编委向宁教授,于2014年10月美国声学学会第168届年会颁奖典礼上,被授于赛宾奖章(Wallace Clement Sabine Medal)。赛宾奖章是美国声学学会为表彰国际上建筑声学有杰出贡献的学者而设立的荣誉奖章。向宁教授为自1957年设立该奖以来第16位得主,也是首位获得该奖章的华人科学家。此前得该奖章的声学家有如V.Knudsen(美)(马大猷先生导师),L.Beranek(美)(马大猷先生同窗),E.Meyer(德),L.Cremer(德),Marshall(新西兰),J.Bradley(加)等人。向宁教授25年来对耦合空间声场研究领域做出的杰出贡献,并在双耳缩尺模型测     

音乐厅音质设计进展述评

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和听者环绕感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。
