The Nor850 offers evaluation options according to common national and international building acoustics standards. Measurements can be extensively documented and evaluated. If you only discover afterwards that one of the individual measurements contains a disturbance, you can exclude it from the averaging. The results are then automatically updated. If the algorithm was unable to correctly set the compensation line during reverberation measurements due to background noise (which is displayed), this can be corrected manually. The software checks all standard criteria and gives you information about where criteria may not have been met.
Standards included:
ISO 16283-1: Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation
ISO 16283-2: Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 2: Impact sound insulation
ISO 16283-3: Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 3: Façade sound insulation
DIN 4109-4: Sound insulation in buildings – Part 4: Testing of acoustics in buildings
Acoustics — Measurement of room acoustic parameters — Part 2: Reverberation time in ordinary rooms
If you control the measurement via WLAN from your laptop/tablet/smartphone, you can stand outside the transmitting/receiving room. If you measure on 1 channel using the quick method (manual panning through the room), it is more convenient to use the internal building acoustics mode in the sound level meter.
Controlling the measurement via the Nor850 has these advantages in particular:
