套房式语音录音室的声学设计及客观评价

Acoustic Design and Evaluation of Inner Recording Suite for Phonetics

从建筑声学角度出发,采用浮筑隔声房外加隔声墙的双层隔声构造,以隔声量、吸声系数、混响时间等为主要声学指标,建立面向语音学研究的现代化录音室,并对本底噪声进行了评测.结果表明,该录音室的声学效果完全达到使用要求.

According to architectural acoustic principle,this paper describes the designing of modern recording studio which is built by using the double sound insulation structure containing sound-proof board for floating construction and sound insulation wall and taking noise insulation factor,sound absorption coefficient and reverberation time as main architectural acoustics index.The background noise of the recording studio is evaluated and the effect of the recording studio comes up to the requirements for the study of phonetics.
