Sound Intensity

Sound Intensity

The Nor150 fitted with sound intensity option and the sound intensity probe kit Nor1290 is a powerful tool for all type of sound intensity measurements. It is designed for easy use in all types of measurement conditions. 

The remote control handle using a Smartphone as a measurement control and displaying device forms a light weighted and easy to use system, allowing the user to perform all measurements with a single hand operation. The Smartphone communicates via WiFi with the internal web server running in the Nor150. The system may also be used with the sound intensity probe directly attached to the Nor150.

Nor1290 Sound Intensity Kit Datasheet



A new generation of remote control and data acquisition from a sound level meter!
Use your smartphone or notepad to connect with your sound level meter.
The Nor150’s built-in web server opens up a new world of remote communication and acquisition of data from a sound level meter. Simply connect to your instrument via LAN, GPRS, or WiFi using a web browser to control, download, or view the measurement in real time. The program covers all applications from downloading files to full control of your analyser to add markers, start a recording or just check the battery status.



Measurement Parameters

Simultaneous measurement of SPL, Leq, LeqI, LMax, LMin, LE, LEI, LPeak, Ln and Tmax5.
Time weighting functions: Fast, Slow, and Impulse (Simultaneous).
Spectral weighting functions: A, C, and Z - weighting (Simultaneous).
Frequency analysis: 1/1 and 1/3 octave real time filters from 0,1Hz to 20 kHz.
Statistical calculations: 8 individual adjustable percentiles from L0,1% to L99,9%, The statistical calculations are performed in real time within each frequency band and for each profile period if period length is set longer than 2 minutes. User can select between Fast or Slow time weighting as basis for the statistical calculation. 
Measurement Control
