Sound Power Measurements

Norsonic have a comprehensive range of instrumentation for measuring sound power using Precision, Engineering, and/or Survey methods. 

The Nor850 Measurement System is a multi-channel acoustic analyser. The system can be based on channels in an Nor850-MF1 rack and/or multiple Nor140 or Nor145 sound level meters. Both rack-mounted channels and stand-alone sound level meters can be used in the same system. The system supports USB, LAN and WLAN connection. 

The BS EN 61672 Class 1 performance of each channel and be verified by independent calibration laboratories to ensure traceability to national standards.

The Nor850 software can be used both as evaluation software for measurements from the Norsonic sound level meters and as control software. The software guides you in a uniquely intuitive way through the measurement routines according to common sound power standards such as ISO 3741, ISO 3743-1, ISO 3744, ISO 3745, ISO 3746 and ISO 3747. 

The extended Sound Power application package contains required features for making more special tests such as dual-chamber testing of heat-pumps, dynamic testing of earth moving machinery, and similar.

The entire test procedure can be controlled by a user-defined Scheduler for easy test repetitions. 

The Norsonic Nor278 Reference Sound Source is equally suited to lab, field and survey measurements of sound power according to ISO 3741, ISO 3743-1 and ISO 3747. 

The Norsonic Nor150 fitted with sound intensity option and the sound intensity probe kit Nor1290 is a powerful tool for sound intensity measurements to determine sound power in accordance with ISO 9614. The remote control handle, using a smartphone for measurement control and display, forms a lightweight and easy to use system which enables single-handed operation. The Smartphone communicates via WiFi with the Nor150. The sound intensity probe can also be connected directly attached to the Nor150.
