XL2 - 音频与声学分析仪

 

声学和音频分析仪

 
XL2分析仪形成了最先进的声级计,全面的声学分析仪以及功能强大的音频分析仪的独特组合。一系列带电子数据表的测量麦克风可满足您的要求。

除了是一个先进的集成声级计外,XL2还测量RTA和FFT高分辨率光谱,RT60混响时间,极性,延迟和THD + N。可选功能包括语音清晰度STIPA,扩展声学功能,噪声曲线,电影校准,通过/失败分析和远程测量采集。型号认可选项将仪器升级到XL2-TA,这是一种型号认可的声级计。

数据和音频记录到SD卡上,以便传输到计算机。XL2以纯文本格式存储所有报告和日志文件,可以用任何文本编辑应用程序(记事本,写字板等)打开。此外,一系列免费的MS Excel应用程序模板提供了一种便捷的方式来查看特定任务的测量结果并创建简单的报告。可选的XL2数据浏览器软件为记录的噪音监测数据提供全面的分析工具。

广泛的功能是针对测量任务而量身定做的:
  • 已安装声音
  • 生命安全系统
  • 噪声监测
  • 现场声音
  • 广播
  • 建筑声学
  • 工业和航空航天
  • 通过/失败质量控制
