All measurement specific setups are available in this menu. The available settings depends on the
options installed in your instrument. Contact Norsonic or one of our qualified service centres for more information.
The total measurement time is called the 'Global measurement time'. In addition to the Global report,
a measurement may contain Profile reports, which are sequences of periods defined by the different
Profile period times. The Profile measurement levels will be represented in the L(t) views.
The levels are detected using time constants (Fast/Slow/Impulse) to generate time weighted levels.
The instantaneous levels from these time weightings are available also when not measuring, in the idle mode.
These constants are usually defined in measurement standards.
Bandwidth, frequency weightings and range, and FFT is configured here.
The percentiles / level distribution function measures how the sound level is spread out over the
dynamic range. Up to 8 different Ln values are calculated simultaneously. The statistics are based on either LFSPL,
LSSPL or Leq, and the class width is 0.2 dB. Both probability and cumulative distribution functions are available.
A vast number of measurement functions are available. To make the selection of functions easier,
disable the time weightings and frequency weightings you do not need. The function list will then shrink.
Almost any combination of time weightings, frequency weightings (weighting networks and filters) are available.
Hint: Do not select more functions than you actually need!
Emergence Noise
When enabled, emergence noise will be calculated based on the data marked with marker one and two.
Set marker one on all ambient noise and marker two on all residual noise. These markers are predefined in the
environmental standard setup Emergence Noise. To see the emergence noise results, open the context menu in a specter
table display and press 'Show Emergence Noise'.
The audio signal can be recorded (to a wav-file) during the measurements. Different signal quality
selections are available, and also the start / stop and length can be set to correspond to the intended purpose of the
recording.
The instrument can connect to an IP camera to be able to add pictures to a measurement, based on
triggers. You must know the IP address, the username and password to be able to connect to the IP camera.
Several modes are available for storing the measurements. Depending on the job to be done and your personal preferences,
the different modes will help you achieve the easiest workflow.
The Nor150 have support for the Thies Clima Sensor US. Several different
parameters can be enabled for logging. The enabled weather data will be logged together
with profile A. In addition the sensor can be disabled.
