Nor145 kan brukes i mange mulighet applikasjoner.
Nor145 is designed to be the preferred tool for all types of environmental noise measurements.
Nor145 is optimised for use with Norsonic NorCloud, Norsonics’ cloud service for noise measurement, control and reporting, all easy connected over the internal 4G modem.
Features
General analyser (environmental) mode has a selection of different display views. Portrait and Landscape. All Portrait views can either be a single or dual type frame.
Available views in Environmental / General mode are:
FFT – Displays the FFT spectra
FFT (landscape) Displays the FFT spectra as landscape
Level vs frequency (L/f) display single view – portrait
Level vs frequency (L/f) display single view – landscape
Level vs time (L/t) display single view – portrait
Level vs time (L/t) display single view – landscape
A numerical table is associated with all the graphical views – just press the TAB button to toggle between graphical and numerical view. Works both with single and split screen.
Cumulative and Probability Distribution Function /PDF) – landscape view
Cumulative and Probability Distribution Function /PDF) – portrait view
Split view with FFT and 1/3 octave. The link cursor feature connects the cursor in FFT and 1/3 octave displays, making it easy to manoeuvre in the frequency domain
Dual view with L/t and L/f – split view
FFT – Displays the FFT spectra
FFT (landscape) Displays the FFT spectra as landscape
Graphical back erase in Pause mode. Move cursor to remove unwanted noise events and push continue to resume measurement.
Norsonic is known for its long-time tradition of creating the state-of-the art building acoustic analysers. The Nor145 sound level meter is no exception!
It can be used as a stand-alone single channel building acoustic analyser, or as a remotely controlled building acoustic frontend (wireless) for the advanced Nor850 multichannel software thru its hotspot feature.
The Nor145 offers a built-in signal generator for excitation of the source room level measurements or for excitation of the reverberation time measurements. The results are measured in accordance with the ISO 16283 Standard requirements. With additional background level measurement results, the Nor145 offers a on-board calculation of the final airborne sound insulation indices DnT and Rw in accordance with ISO 717. Of course, the similar possibility is available for impact sound insulation index Ln,w using a tapping machine such as the Nor277.
The reverberation time excitation may alternatively be based on an impulsive source. In any case, the Nor145 calculates the results for T15, T20 and T30 in parallel.
The Nor145 analyser is seamless integrated with the Nor850 software; either as a remote frontend to the Nor850 Measurement System, or for easy post processing in the Nor850 Reporting System.
Features:
Building acoustics mode offers application tailored displays to secure a good work flow and control in your project.
Building Acoustics- Upper frame shows Receiving room level with background noise. Running L/t in lower frame to evaluate if unwanted noise appears in the measurement.
Building acoustic – rating view 1, calculated sound insulation together with the single number index.
Building acoustic – rating view 2, numerical table to present the single number index along with the spectrum adaption terms.
Building acoustic – rating view 3, all numerical results of the analysis plus a level overview graph.
Building acoustic – rating view 4, background noise vs. receiving room levels.

STIPA mode is easy and intuitive to use. The display is composed of a fixed view with two frames. The upper shows each frequency band, while the lower shows the measured values including a bar graph.
STIPA – By selecting the lower part of the display and pressing the TBL button, the two modulation indexes for each of the STIPA-octaves will be displayed.

Inneholder
Krever BA-BASIC opsjons pakke.
GPS brukes for posisjon og nøyaktig tidssynkronisering. Tidssynkronisering er spesielt nyttig når flere Nor145 enheter brukes for å måle den samme støy-hendelsen, f.eks. ved overvåking av en eksplosjon. GPS-posisjonen er lagret som en del av målefilen. Det kan også angis å være en del av filnavnet.
Med et eksternt IP-kamera kan du lage hendelsesbaserte bilder. Bilder tatt under en måling er merket som hendelser i L/t grafen og kan vises i Nor145, i NorCloud eller i NorReview.
Denne opsjonen kan ikke ettermonteres og må derfor bestilles sammen med instrumentet.
Ordre kode: Nor145/01
Med denne opsjonen kan man koble instrumentet til Norsonics skybaserte støyovervåking – NorCloud.
ENV-Advanced opsjonen må være installert.
Fungerer parallelt med 1/1- eller 1/3-oktav analyse.
Split view with FFT and 1/3 octave. The link cursor feature connects the cursor in FFT and 1/3 octave displays, making it easy to manoeuvre in the frequency domain.
The ultrasound option adds the following features to a standard Nor145:
A ¼” microphone is recommended to measure correctly due to the limitation in the frequency range of a standard ½” microphone.
