Designed for Real-World Measurement Conditions

It is characterized by its particular practical suitability and user-friendliness in all conceivable measurement environments. Based on a novel method invented by Norsonic for correcting the phase response of a sound intensity analyzer, the entire frequency range can be measured with just one spacer!

The remote-control handle using a smartphone as a measurement control and displaying device, forms a light weighted and easy-to-use system. This allows the user to perform all measurements with a single hand operation. The smartphone communicates via WiFi with the Nor150. The system may also be used with the sound intensity probe directly attached to the Nor150.

Unique feature

Based on a novel method invented by Norsonic for correcting the phase response of a sound intensity analyzer, the Nor150 offers the following outstanding unique selling points for sound intensity measurements:

Measurement of the complete frequency response with the 12mm spacer
Significantly higher dynamics than required in common ISO standards

The procedure for this correction of the phase response is so conveniently integrated into the Nor150 that it can be carried out very quickly and easily before each measurement!

Dynamics with a 12mm spacer

The diagram shows that, thanks to the new algorithm with a 12mm spacer, this measuring system already meets the requirements that IEC 61043 describes for a 100 mm spacer:
