Lns 7-14 are user defined, turned off by default.
Ln values are calculated using 1/16 second LAF samples by default. Sampling rate, time
weighting and frequency weighting can be changed in NoiseTools.
Instruments with the “statistical levels x 2” capability provide a second set of 14 Ln values which
can be configured within NoiseTools using independent sampling rate, time weighting and
frequency weighting.
