4 概述
噪声统计分析仪是指用于环境噪声监测，并进行统计分析的声学测量仪器。它能根
据所选择的采样时间及采样间隔进行自动采样，采样结束后自动计算并打印或显示出等
效连续声级L,,累计百分数声级LN，同时也可打印出累计噪声分布曲线等。噪声统计
分析仪通常由声级计和处理器两部分组成。
5 计.性能要求
5.1 指示声级调整
5.1.1 为检验和保持噪声统计分析仪的指示声级准确，应使用说明书中规定型号的声
校准器，用于在噪声统计分析仪参考级量程的参考声压级上和检验频率上进行校准。对
1级噪声统计分析仪使用 JJG 176-2005《声校准器》规程中规定的1级声校准器、2级
噪声统计分析仪使用1级或2级声校准器。
5.1.2 在校准检验频率上，使用说明书应提供校准的方法和调整数据，使其指示等效
于在参考环境条件下从参考方向人射的正弦平面行波响应或无规人射声响应的声级。对
使用说明书上规定使用的所有型号的传声器和为传声器安装的相关附件，如风罩，在使
用说明书中应提供相应的调整数据。
