NEW Webinar: Acoustic Performance of Classrooms

Check out our new webinar: Thursday, 25th April 2019

The acoustic performance directly affects the speech intelligibility within a classroom, which in turn has a big impact on the learning success of the students. The webinar therefore explains how to evaluate the acoustic performance, introduces typical target specifications, and introduces potential measures to improve a deficient classroom.

The webinar is held in english and german at different times during the day. Register for your most convenient date and time!

How to measure Reverberation Time

You will find:
  • Instruments for measuring RT60
  • “How to…” guides and videos

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.
