NoiseLab-Lite 4+

NoiseLab-Lite是一款由中科新悦 (北京声望集团)开发的专业噪声测量应用，它能将您的iOS设备转变为专业的声音水平计(SLM)，精确测量您周围的声音压力水平。

这款应用的主要功能包括支持内置麦克风和外部麦克风，后者有3种增益可供选择。它还能进行任何滤波器Z、A、B、C和时间探测器Fast、Slow和Impulse的组合测量。

对于声学工程师来说，其遵守IEC和ASTM标准，可以使用外部麦克风。推荐使用MicW i437麦克风进行高精度测量，i437可以在Amazon和其他在线商店购买。

NoiseLab-Lite的界面布局非常简单，您可以直接选择【启动/暂停】按钮进行相关数据的测试。进入应用后，界面上部是计权模式和档位选择，下部是SPL实时声压级的显示，便于实时测量使用。最下面的是测试曲线显示，可以根据设置记录SPL、MIN、RMS、PEAK四个值随时间变化的曲线

HIGHLIGHTS:
- Support the built-in Microphone and the external microphone, the latter has 3 gains to choose.
- Measurements of any combinations of Filter Z, A, B, C and Time detector Fast, Slow and Impulse simultaneously.
- The system can be calibrated by using sound calibrators with 94 dB and 114 dB at 1000 Hz, or manual input of calibration factor.
- Measured time history of sound pressure level can be saved into the list of history report and easily export to computer and send by email.
