Measurement workflow for sound intensity

Nor850 Sound Intensity implements a workflow tailored to standardized sound intensity measurements, covering all stages from acquisition to reporting:

Definition of measurement surfaces around the sound source according to the selected method
Data acquisition using sound intensity probes, both at discrete points and by scanning across the measurement surface
Automatic calculation of sound power in accordance with ISO 9614
Generation of standards-compliant test reports

This workflow enables reliable results directly on the source, under real measurement conditions.

Integrated within the Nor850 system

Nor850 Sound Intensity integrates with Norsonic hardware, including intensity probes, sound level meters and data acquisition systems, enabling flexible configurations for sound power measurements under real operating conditions.

The system combines measurement control, data processing and reporting within a single working environment, ensuring consistency and reliable validation of results.

Nor850 covers the main sound intensity measurement scenarios in industrial and field environments.

Sound power determination using intensity

Determination of sound power for machinery, equipment and installations directly in their operating environment, even in acoustically complex conditions, such as environments with high background noise or the presence of reflections.
