The XL2 as a Sound Level Meter

Numerous measurement variations are simultaneously available. Actual level (live), Lmin, Lmax, Leq and Lpeak may be measured in combination with frequency weighting A, C or Z and time weightings fast, slow and impulse. All results are simultaneously available and may be stored automatically for later documentation.

I Love It! 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.

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

Better price with more versatility! I am happy that you keep on developing new applications and uses for the XL2, it is quite a convenient and powerful tool. In my opinion it is a serious competition for the traditional sound level meters at a better price and with more versatility. The Type Approval is an important step forward in the acceptation of the system; even in situations where type approval is not really needed, it helps avoiding discussions on the validity of the measurements.

XL2 Data Explorer Software! With regards to analyzing the recorded noise data: The idea of hovering over the marker text or locking the set of them is absolutely brilliant for assessing the tonality of a marked section. I could not have thought of a better system. And the percentile calculator letting you choose any marker, filter band or level parameter is just perfect.
