本文详细报告了重庆、自贡、内江等地现有一些地下公共建筑(电影院、会议室、旅馆、酒吧间、录像放映室、舞厅等)的声学环境调查情况,测定了上述地下空间的混响时间T_(60),环境噪声级,调查了地下空间室型、材料装修情况,噪声源位置及传播情况等。为进一步开发并有效地利用地下空间,充分发挥公共性地下建筑功能,建议把声环境要求纳入地下建筑设计规范;并进一步研究地下建筑规划和声环境之间的关系;地下声环境的标准和要求;适应地下环境的声学构造和材料;地下建筑室型特征和声学效果的关系等。通过大量调查研究后,本文作者认为:地下建筑在适应特殊要求的声学建筑方面诸如录音室、播音室之类音质要求高的建筑和高噪声车间等,具有独到的优越性,地下空间的开发应该是大有可为的。
This article details the acoustic environment surveys of existing underground public buildings (cinemas, conference rooms, hotels, bars, video screening rooms, ballrooms, etc.) in Chongqing, Zigong, and Neijiang, and measures the reverberation time of the underground space mentioned above. T_ (60), the environmental noise level, investigated the type of room in the underground space, the decoration of the materials, the location of noise sources, and the spread of the noise. In order to further develop and effectively use underground space and give full play to public underground building functions, it is recommended to incorporate acoustic environmental requirements into the underground building design specifications; and to further study the relationship between underground building planning and acoustic environment; standards and requirements for underground acoustic environment Acoustic structures and materials that adapt to the underground environment; the relationship between chamber type features and acoustic effects of underground buildings. After a large number of investigations and researches, the author of this paper believes that underground buildings are uniquely superior to acoustic buildings that meet special requirements, such as studios and studios, which require high sound quality and high-noise workshops. Underground space development should be It is very promising.
