Building and Room Acoustics

Norsonic have been providing comprehensive and integrated solutions for Building Acoustics for more than 20 years. But Norsonic don’t rest on their laurels, they continue to spend 20% of their turnover on product development so the best products keep getting better. 

If you are looking for the quickest slickest system to carry out sound insulation testing on site you’ve come to the right place. The combination of a Norsonic Nor145 sound level analyser, Nor282 Power Amplifier, Nor283 Dodecahedron Speaker and Nor277 Tapping Machine integrates seamlessly for rapid and professional measurements on site. The Nor145 and Nor282 communicate with each other wirelessly. The whole system can be battery-powered and the tests can be run directly from the Nor145 or a smartphone or laptop.

If your focus is more on keeping the costs down, whilst not compromising on quality, the combination of Norsonic Nor140 Sound Level Analyser, Nor280 Power Amplifier, Nor283 Dodecahedron Speaker and Nor277 Tapping Machine offers excellent quality equipment at a really competitive price. 

The Nor145 is the ideal sound level meter for room acoustic measurements. Thanks to the large colour and touchscreen, not only the numerical reverberation time values, but also the decay curves of the individual frequency bands can be displayed very clearly. The averaging of several reverberation time measurements and the evaluation according to ISO 3382 can be carried out in the meter.

The STI option supports the latest revision of the STIPA standard, IEC 60268-16 revision 5. The Nor145’s built-in signal generator generates the STIPA signal. Background noise correction and/or auditory correction can be applied in the meter. With the Nor145, a complete measurement sequence takes only 21 seconds.
