The Nor150 is the most advanced dual-channel Class I sound level meter available featuring environmental noise, building acoustics, vibration, and sound intensity measurement and analysis.
The Nor150 is a Class I sound level meter designed for a wide range of tasks ranging from basic noise measurements to advanced noise analysis, including room and building acoustics applications. Featuring dual measurement channels, the Nor150 is an ideal tool for sound intensity measurements when paired with the Nor1290 sound intensity probe. It also supports vibration measurements when paired with an IEPE vibration sensor. Featuring a 4.3″ full-color touchscreen, it offers a user-friendly experience similar to that of a smartphone.
The Nor150 can also be managed via NorCloud and the Nor850 software. The included NorConnect software with every unit enables users to download, view, and generate Excel reports of the measurements, or perform further analysis using Norsonic’s software suite of postprocessing and reporting tools for building acoustics, environmental noise, sound power, and sound intensity.
The Nor150 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 down to 5 ms. All interfaces and voice and text annotation are included. Input for second channel (Option 2), and a built-in web server is a standard feature.
Vibration measurements are made easy with the Nor150 using IEPE powered accelerometers. By enabling IEPE power, an accelerometer can be directly connected to the 7-pin preamplifier LEMO socket on each channel via a suitable cable, such as the Nor1438. The Nor150 can be set up to measure any combination of acoustic and vibration measurements using both measurement channels simultaneously.
Each Nor150 is delivered with the following:
The Nor150 Analyzer is built to be expandable and upgradable, providing users with a comprehensive measurement tool for years ahead. Each unit includes Norsonic’s 3-year warranty. Norsonic’s retrofit policy guarantees regular software updates with new features and options. The Nor150 offers a 60-day trial period where all options are enabled by the user if and when needed.

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 for the second channel 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. Also included is SysCheck signal for check of outdoor microphones like the Nor1216 and Nor1217. Second channel is a standard feature included with the base meter.
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 additional background level measurement results, the Nor150 offers an on-board calculation of the final airborne sound insulation ratings such as ASTC, NIC, DnT, Rw and others. Similar possibility is available for impact sound insulation ratings Ln,w or AIIC.
Enhanced noise assessment package including internal web server for remote control via smartphones, pads and PC and additional four triggers for independent setting of different trigger levels during a day. Requires option 4.
With this option you are able to connect the instrument to Norsonic’s cloud service; NorCloud.
