The data can be displayed remotely on any PC, notepad or smartphone. From the same device, you may change settings or simply check the status of the Nor150.
Features
Nor150 offer four different views. You can customize each view as you like and rotate between the views using the VIEW button.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:
Sound level meter display, only showing global values
Nor150 view – Level vs time display is a Profile display showing the selected level function versus time, but no global values. – available as portrait in single and dual frame mode.
Nor150 view – Level vs time, but only available as landscape (wide) in single frame mode
Nor150 view – Dual view with L/t and L/f
Level vs frequency display is a Spectrum display and can show spectra for both the on-going time profile and the global results at the same time. Available as portrait in single and dual frame mode.
Nor150 view – Level vs frequency display – wide, only available as landscape (wide) in single frame mode. The graphical display is turned 90 degrees.
Nor150 view – Ln – Combined cumulative and statistical percentage display – only available as single frame display
Nor150 viewLn – Combined cumulative and statistical percentage display. The graphical display is turned 90 degrees
FFT – Displays the FFT spectra
FFT (landscape) Displays the FFT spectra as landscape
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.
Numerical tables – each graphical display has a numerical table as an alternative. Use the TBL button to switch between graphical and numeral display. The TBL button is assigned to the active window. To produce a picture like the one shown below, first tap the lower display so it is active then use the TBL button to switch the lower display numerically.
Norsonic continue its long-time tradition for creating the state-of-the art building acoustic analysers. The Nor150 is no exception in this respect! It can be used as a manually operated single or dual channel building acoustic analyser, or as a remotely controlled advanced building acoustic frontend for the Nor850 multichannel system.
The Nor150 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 Nor150 has an 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 Nor150 calculates the results for T15, T20 and T30 in parallel.
The Nor150 analyser is seamless integrated with the Nor850 software, either as a remote frontend to the Nor850 Measurement System, or as a manual measurement tool for exporting measurement files to the post processing Nor850 Reporting System.

Applications
Features
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
Nor150 basic
Nor150 basic unit includes A, C and Z weighting networks with measurement of Leq, LeqI, LE – sound exposure level, SPL, Lmax, Lmin with parallel detection of Fast, Slow and Impulse time constants, statistical calculation of Ln, and TMAX5. The measurement data is analysed as global values in addition to two parallel time profiles with an adjustable resolution ranging from ms to 2h. All interfaces and voice and text annotation included.
Option packages:
Nor150 Advanced Level option kit (e.g. for ENV) incl. options: 3, 4, 11, 12.
Nor150 Building Acoustic option kit incl. options 3, 7, 8, 9.
Nor150 Consultant package option kit cincl. options 3, 4, 7, 8, 11, 12, 13.
The internal camera is meant for documentation purpose before or after a measurement. The picture files are stored in the same project files as the measurement it belongs to.
Event triggered pictures requires an external IP camera or camera found on devices such as smart phones or pads. Pictures captures during a measurement is marked as events in the L/t graph and can be view in Nor150 or in NorReview.
The GPS is used for position identification. Later software versions will also support exact time synchronisation. Time synchronisation is especially useful when several Nor150 units are used for capturing the same noise event, such as blast monitoring. The GPS position is stored as a part of the measurement file. It may also be set to be a part of the file name.
This option is not available as retrofit and must be ordered along with the instrument.
Input channel two is located on the left side of the instrument, well protected from dust and moisture by a rubber cover.
The second channel is a standard 7 pin Lemo connector with the same specifications as the main channel. It supports both standard 7 pin lemo preamplifiers as well as IEPE preamplifiers and accelerometers. Included is also SysCheck signal for check of outdoor microphones like the Nor1216 and Nor1217.
This option is not available as retrofit and must be ordered along with the instrument.
1/1 and 1/3 octave filters (0,4 – 20 kHz in 1/3 octave band) including multi-specter functionality in time profile A.
A 3 order analogue high pass filter with a -3 dB point at 3 Hz may be selected to avoid overloading the input circuitry from low frequency noise.
This option extension adds audio recording and marker management to the Nor150. In Nor150 you can replay the recording on the meter itself without any need of transferring the data to a PC. The option 4 adds a sophisticated but easy to use marker management indispensable for every environmental noise assessment tasks. The user can select up to ten makers, add names, colour and associates the marker to an action. The marker can either be a single or a toggle marker. The action can be; enable a reference tone, start a recording, take a picture or set one of the digital outputs found on the 15pin socket. It is easy to add markers on an ongoing measurement. Voice and text notes may in the same way as markers be added to an ongoing measurement. The markers can be moved or deleted. Markers may also be added after a measurement is elapsed.
The Nor 150 also offers six system markers that are automatically inserted in the Level versus time profile. These are; Measurement Pause marker, Measurement continue marker, Audio recording marker, Picture marker, Signal overload marker, Battery low marker, Event trigger marker.
The Nor150 is seamless integrated to the PC program NorReview (Nor1026) to further evaluate and calculate the noise data and to create customized reports.
Features
Sound intensity is a powerful measurement method in situations where traditional methods prove difficult or not feasible. With the new features of the Nor150, sound intensity measurements are significantly easier to accomplish than ever before and may actually be less time-consuming than corresponding sound pressure methods.
Nor150 equipped with the sound intensity option and the Nor1290 probe kit is a powerful tool for all types of sound intensity measurements, from high-precision laboratory conditions to demanding and rough field use.
Thanks to the unique phase correction algorithm, only a 12 mm spacer is necessary to cover the entire frequency range from 25 Hz to 10 kHz. This significantly reduces the time spent in-situ, and allows measurements of highly reactive sound fields.
Sound intensity is especially suitable for sound power measurements of non-movable machinery in industrial environments, measurements of driven machinery, industrial plant exhausts and pipes both indoors and outdoors.
In-situ building acoustics may benefit from the intensity technique, both for transmission loss and sound leakage detection. And for research & development applications, sound intensity provides powerful noise map visualisation.
