1、学生实验报告（理工类）课程名称：专业班级：学生学号：学生姓名：所属院部：指导教师：20 1120 12学年第2学期金陵科技学院教务处制实验项目名称：环境噪声测量实验 实验学时：4同组学生姓名：实验地点：实验日期：实验成绩：批改教师：批改时间：一、实验目的和要求（1）掌握噪声测量的方法，对噪声的大小有一个主观的认识（2）学会使用声级计；（3）分析噪声的大小与来源，得知建筑是否符合规定。二、实验仪器和设备HS5633型声级计三、实验过程（1）测点的选择：建筑物外1m处，高1.2m;（2）检查声级计的电池电力并采用校准器对其进行校准；（3）测量应在无风雪、无雷电天气，风速5m/s以下进行。大风时应

2、停止测量；（4）记录声级计读数值，保持声级计在L档，每隔5秒读一个数值, 共记录200个数。四、实验结果与分析原理：将记录的200个数从大到小的顺序排列，第20个数值就是L10， L10反映交通噪声的峰值；第100个数值就是L50，第180个数值就是 l90，l90反映背景噪声值。等效声级反映了在测量的时间内声能的平均分布情况。计算公式：Leq=L5o+d2/60 其中d=Lio-L9o 测量得出数据（单位：db）：167.72658.45157.07654.210152.412651.415149.417648.1267.52758.45256.87754.210252.412751.315
