CENTER-392 Integrating Sound Level Meter (IEC 61672-1 class 2)
You will find this article in our Webshop
In contrast to cheaper sound level meters, this device can measure the LEQ according to IEC61672. Most sound level meters can measure the sound level with time weighting F (fast) or S (slow).
However, in practical measurements, integrating sound levels are most important. Integrating means energy equivalent averaging. This calculation differs from a simple arithmetic average.
