The Noise Criteria option software allows the DS analyzers to analyze room environments and to compare the sound spectrum to official Noise Criteria Standards. Results in the NC range of 63Hz to 8kHz are compared to the standard NC curves. This comparison is displayed along with the octave frequency information.
Noise Criteria Frequencies: 63, 125, 250, 500, 1000, 2000, 4000 & 8000Hz.
Option Kit Contains: An upgraded EPROM device and software upgrade.
