Webinar: Combining Sound Level Measurements into a Single Report

10 December 2020, 07:00 / 13:30 / 15:00 / 18:00 (CEST: Paris, Berlin)

An often-recurring challenge in the analysis of long-term sound level measurements is the integration of various data sets into a single final report. For instance, several 24-hour recordings may have to be concatenated into one project, or the overall Rating Level be calculated based on a group of results.

This webinar therefore explains the process of combining sound level measurements, explains the difference between the Day/Night vs. the Rating Level, and proposes a practicable procedure to create a single professional report from the project data.

The presentation will be offered in English and German. Register for your most convenient date and time!


The XL2 is currently the world’s most versatile hand-held acoustic and audio analyser. I can do so much with it, and just love it! And in many ways, the associated Data Explorer software is much more versatile and easier to use than other leading industry equivalents.

I must say that the instrument and the software are brilliant, and very simple to use, even for an old fogey like me.

The art of audio repair and restoration is alive and thriving at NTi Audio. They are tech wizards. They brought a beloved Tester back to life.
It had completely failed after being in service for 37 years. This instrument was no longer being manufactured and could not be replaced. NTi stepped in and worked their magic to make it good as new. Bravo! Bravissimo!
