The Nor150 Analyser is designed to be expanded and upgradeable to give you a complete measurement tool for years to come. Norsonic’s retrofit policy ensures regular software updates with new features and new options followed by a 3 years warranty.
Option packages:
Nor150 Advanced Level option kit (e.g. for ENV) containing option: 3, 4, 11, 12.
Nor150 Building Acoustic option kit excluded on board rating incl. option 3, 7, 8.
Nor150 Consultant package option kit containing option 3, 4, 7, 8, 11, 12, 13.
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.
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. The Nor150 is the third generation of sound analyser from Norsonic that is fitted with audio recording. We were the first company that added audio recording into a Sound Level Meter. With the introduction of Nor150, the audio recording is further refined with the possibility to also 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.

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.

With this option you are able to connect the instrument to Norsonic’s cloud service; NorCloud.
NorCloud is a Norsonic system to collect, display and process sound level data.
When used together with Nor150 sound analyser, you can measure, analyse and report directly from your web browser.
Create projects, assign sound level meters to projects and configure settings such as audio recording, SMS/e-mail alarms and automatic reporting.
Norsonic stores your data safely and conveniently, but you are of course free to download your measurements.
FFT sampling rate is 48 kHz with more than 16000 lines. Upper frequency is 22 kHz. Dynamic zoom from 1 – 64. The FFT calculation and 1/3 octave spectrum works in parallel.
The STI mode supports the latest revision of the STIPA standard, IEC 60268-16 revision 5.- Additional features are background noise correction and auditory correction.
- Background noise correction can be turned on/off.
- Auditory correction gives a lower score on the STI value if the STIPA noise signal is too loud or too low. It shall normally be turned on, but the latest revision of the standard recommends it to be possible to turn it off in some special circumstances.
- The built-in signal generator generates the STIPA signal.
- A complete measurement sequence takes only 21 seconds.
- 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.
