【摘要】 内廊式教学楼是沿走廊两侧排列一组或两组教室并在端部安排卫生间,楼梯问或办公室等服务用房,组成综合的空间单元。它的特点是教室相对集中,面积紧凑,内部交通线比较短,而且大多数内廊兼休息厅使用,使用时间集中,人流拥挤,教室之间相互干扰大,因此这种建筑组合形式的教学楼室内噪声较大且混响时间较长,对教室内声环境产生一定的负面影响。本文针对这类教学楼室内声环境整体效果进行研究,涉及到建筑形式及功能分区；空间组合；建筑材料；教学设备及声环境设计等因素。本文通过查阅相关文献资料,在国内外研究成果的基础上,结合现场实地测量,分析研究教学楼室内及周围环境各种声音的特性。在此基础上制定调查问卷,并在教学楼内及周围发放,将调查问卷各项结果进行系统分析,采用模糊数学中的综合评价法对具有代表性的内廊式教学楼西安铁一中一号教学楼室内声环境的主观评价。用模糊数学的目的是把主观上受访者对该教学楼走廊声环境的不同感受评分的百分比,通过计算用-个具体的数值代表受访者对西安铁一中一号教学楼室内声环境的评价状况。由调查分析和计算,最后得出受访师生对西安铁一中一号教学楼室内声环境的评价结果是：认为课间教学楼内各种声音最嘈杂,声音清晰度不高,声环境整体效果较差；其次是上课教师间互相干扰。因此在调研分析的基础上从声环境的评价入手,通过对铁一中教学楼室内声环境进行测量,搜集数据和系统分析,借鉴国内外成功公建室内声环境设计案例提出科学合理经济可行性改造建议。更多还原

【Abstract】 Inner-corridor style classroom building has one or two sets of classrooms ranking along an inner-corridor on both sides; and rest rooms, staircases, offices or service rooms by the two ends of corridor, so as to become a space unit. It features centralized classrooms, compact area and short traffic range. But as most inner-corridors are also used as lounge hall, it can cause crowding in its service time and big mutual interference between classrooms. As a result, in this type of classroom building, the indoor noise and long reverberation time have negative impact on Indoor Acoustics. In this paper, the writer will do researches on the overall indoor acoustics in this type of classroom building, concerning architecture form, function division, spatial organization, construction materials, teaching equipments and acoustic design, etc.Based on domestic and abroad research results, along with on-site measurements, this paper analyzed and studied various acoustic characteristics both inside the classrooms and in the surrounding environment. On this basis, the writer made a questionnaire and did a survey on teachers and students inside and outside the classroom building, finally did statistics and analysis on the survey result. Using Comprehensive Evaluation Method of fuzzy mathematics, this paper evaluated the indoor acoustics of the representative No.1 classroom building of Xi’an Tie Yi Zhong. The purpose of using fuzzy mathematics is to compute the percentage of the subjective survey results into a specific value to represent the acoustic condition.As analyzed and computed, the interviewed teachers and students evaluated the acoustic condition of No.1 classroom building as:when class break, it’s most noisy inside the building, voice articulation is low, overall acoustics is poor; in addition, there exists mutual interference between teachers in class. Therefore, through research and measurements of this building, along with analysis of the data, this paper offered reasonable and feasible suggestions to the indoor acoustic environment improvement of this kind of classroom building.更多还原
