How do I ensure accurate sound level measurements on site?
Use the XL3 or XL2 with a suitable measurement microphone and perform a quick acoustic calibration with a sound calibrator (typically 94 dB at 1 kHz) before and after the measurement session. This creates traceable results and helps catch setup or microphone issues early.
Do the XL3 and XL2 support STIPA speech intelligibility testing?
Yes. With the STIPA Option installed, the XL3 or XL2 measure speech intelligibility according to IEC 60268-16:2020 (and also support older editions), including features like ambient noise correction and automated averaging.
How do I export XL2 data and create professional reports?
You can transfer XL2 measurement data to a PC and generate professional reports with NTi Data Explorer, which is designed for fast analysis of sound level data and quick creation of customized reports. It automatically includes relevant header information such as measurement date and calibration details for clean documentation.
For building acoustics workflows, you can also export and document key results for SIR (Sound Insulation Reporter) and RAR (Room Acoustics Reporter) applications – making it easy to turn XL2 measurements into standardized, client-ready deliverables.
