【摘要】 本文主要针对国内剧场舞台机械噪声测试和控制的基本需求,对舞台机械排放噪声标准进行了研究。根据标准化噪声测试和控制的方案,主要研究内容包括测试环境和条件、测试设备、测量位置、测试对象、测试流程、噪声修正方法、测试记录和排放噪声限值等。同时,为了满足不同类型剧场舞台机械的评价,将排放噪声限值进行了三种级别的分类,测试结果可根据分类标准进行等级划分。本文的研究为进一步设置针对演出场所的舞台机械噪声标准草案研究提供了基础,具有一定的实用价值和推广意义。更多还原

【Abstract】 According to the demand of stage machinery noise detection and control for domestic modern theatre,this paper has mainly studied the whole content for emission noise standard. The test environment and condition,measurement equipment,detection position,tested object,testing flow,correction method,recording method and limit value are discussed in it. For the measurement results of different kinds of stage machinery,we have classified the limit values into three levels. This research aims to provide the basic work for developing the related draft standard for stage machinery noise,which has certain application value and popularization significance.更多还原
