Multichannel Systems


Testing the sound power of electrical and mechanical equipment is an important aspect of product development. Many products require sound power testing from washing machines, tumble dryers, refrigerators to vacuum cleaners and even construction machinery should be tested to required industry standards.

Product sound power

  • Chainsaws
  • Vacuum Cleaners
  • Washing machines
  • Leaf blowers
  • Other products & machinery

Construction machinery sound testing

Earth moving machinery such as:

  • Dozers
  • Scrapers
  • Graders

ISO Standards

  • ISO3741
  • ISO3743-1
  • ISO3744
  • ISO3745
  • ISO3747

Since many of these products have multiple sound sources, and have a sound which changes over time during the operation of the product, a good method of testing sound quality must satisfactorily divide the sound for testing.

The multi channel software Nor-850 module for sound power testing offers an intuitive and direct solution for complete measurement and reporting according to ISO standards. The system automatically calculates the Sound Power of the product and display the resulting sound power frequency spectrum.
