Precise Noise Prediction Software in Numerous Areas of Application

Whether ISO 9613-2 or CNOSSOS-EU – IMMI supports you in any aspect concerning noise immission control

Depending on the type of noise and the legal requirements of the country, the calculation is based on the relevant dispersion model. You will be supported by individual program functions according to your application. In addition to outdoor sound propagation, IMMI also allows the calculation of sound propagation in rooms, including a function for room acoustic design according to DIN 18041 and the propagation of air pollutants.

You can use IMMI for 

  • Calculating industrial noise
    IMMI supports you with any question in the field of industrial noise – from the calculation of a new supermarket according to TA Lärm, the assessment of sports or leisure facilities as well as the calculation and assessment of construction noise.

  • Calculating traffic noise
    IMMI is best suited for the calculation of traffic noise according to 16. BImSchV or conveniently applicable in urban land use planning according to DIN18005.

  • Calculating noise in working areas
    The Indoor Module is ideally suited for the analysis of the noise situation in workspaces according to DIN 18041.

  • Calculating aircraft noise
    IMMI's Aircraft Noise Module was developed specifically to meet the requirements of aircraft noise prediction. The IMMI software meets the requirements of the German Federal Environment Agency for a program for the calculation of noise protection areas at airports according to AzD/AzB 2008.

  • Noise mapping and action planning
    IMMI enables precise noise mapping according to the EU Environmental Noise Directive 2002/49/EC for road traffic noise, rail traffic noise, industrial noise and aircraft noise and updates thereof in accordance with Directive (EU) 2021/1226.

  • Calculating air pollutants
    With the Pollutant Module in IMMI, the dispersion calculation of gas, dust and odor is possible according to the particle model (TA Luft 2021/AUSTAL) as well as the Gauss model (TA Luft 1986).
