Noise Prediction for Road, Rail, Industry and Wind Turbines

iNoise is intuitive and quality assured software for noise calculations in the environment. The calculations are based on the ISO 9613 and CNOSSOS-EU methods and the recommendations of the quality standard ISO 17534. The GUI is based on the Windows design rules for a genuine Windows user experience.

Quality assured software

The CNOSSOS-EU and ISO 9613 standard are among the most used noise prediction method worldwide. Many countries refer to these standards in their noise legislation. However the standards do not contain guidelines for quality assured software implementation, which leads to differences between applications in calculated results. In 2015 this changed with the release of ISO/TR 17534. This quality standard gives clear recommendations for interpreting the methods. iNoise fully supports these recommendations. The models and results for the test cases are included in the software.

iNoise supports the quality assurance interface (QSI format) for exchanging model data with other noise prediction software.

I found it really easy to get to know the program using the ‘Getting Started’ guide.  I found the menu’s and functions very intuitive.  I typically found that when I thought a function should exist, it did and it was where I expected it to be.
