Nor850 Reporting software (850/RA): Room acoustics according to ISO 3382

Overview

The room acoustics module 850/RA offers the complete evaluation according to ISO 3382-2 (ordinary rooms) and ISO 3382-3 (open-plan offices). The reverberation time T for the evaluation according to ISO 3382-2 can be measured via the impulse or noise excitation, either first in the sound level meter or directly via the Nor850 software – with wireless control of the Nor145 sound level meter and power amplifier via WLAN. In addition to the evaluation according to ISO 3382-2, the Module also enables the measurement of the room impulse response using the SweptSine excitation followed by calculation of the reverberation time and speech intelligibility, as well as the complete measurement routine and evaluation for open-plan offices according to ISO 3382- 3, including generating the test report with all single values ​​(D2,S; Lp,A,S,4m; rD, rC, Lp,A,B). Completely wireless – no more hassle with cables!

Applications & Uses

• Environmental noise surveys to national standards
• Occupational noise assessments (dose, peak, octave data)
• Building acoustics add-ons for RA/STIPA/RT tasks
