The Norsonic sound analyser Nor150 and intensity probe Nor1290 is a powerful tool for sound intensity measurements. Offer optimum user friendliness in all environments, field or laboratory. A unique phase correction algorithm eliminates the use of two spacers to cover the full frequency range. Phase check is done ever so fast by using swept sine instead of random noise in the sound intensity calibrator.

The probe uses a smart phone as control and display unit, allowing single hand operation in situ. An automatic sequence of segments and measurement of quality indicators further improves the user friendliness. Data is easily exported to the Nor850 reporting and evaluation software.
