Sound Intensity Measurements

The Norsonic Nor150 fitted with sound intensity option and the sound intensity probe kit Nor1290 is a powerful tool for sound intensity measurements. The system is compliant with IEC 61043 Class 1 and there is full on-board support for ISO 9614-1 and ISO 9614-2 sound power measurements. 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 connected to the Nor150.

It can be helpful to use the Nor850 Software Sound Intensity option when working with the data. 

The Nor850 Software provides intuitive visual tools for editing. It is possible to copy segments or surfaces, view intermediate results of a subset of segments, exclude segments, surfaces or bands. The measurement results can be up/downgraded between Survey/Engineering, and the weighted frequency range can be changed. 

The Nor850 Software displays all the information as the Nor150, including the Scope Selector and all functions. In addition, the results are mapped onto a 2D/3D surface for noise mapping.

A typical application may be the case where limited time did not allow for a full definition of segments before measurement. All measurements can be made on a single surface where the areas are not defined. By opening up the two measurement projects in Nor850, you can define a new total measurement surface and copy/paste each measured segment into correct locations in the new project.

If you are not certain what you need, ANV’s qualified acoustics and vibration team would be happy to discuss your application. There’s always an acoustician to talk to at ANV during normal UK office hours.
