IMMI – The Software Solution for Noise

As one of the leading software tools in immission control, service providers, authorities and industrial companies have been relying on IMMI for more than 30 years. IMMI is our software package for noise calculation outdoors, noise pollution in working areas and dispersion of air pollutants.

Life is not only becoming faster and faster, but also louder and louder. Caused by industry and commerce, traffic or neighbors – we are surrounded by noise almost around the clock. Some loud and disturbing like the permanent building site next door or the main road in front of our door, others under our own control like the radio in our car. The threshold at which the individual perceives a sound as noise varies greatly. What is certain, however, is that the exposure to loud noise can impair performance and sleep, reduce the quality of life and, in the worst case, even cause illness. In order to ensure compliance with limit values and, if necessary, to develop effective noise reduction measures, a well-founded noise forecast is essential. 

There is a wide variety of laws, directives and standards relating to immission control  – at national, European and international level. They all have a common goal: to protect the population from disproportionate and harmful noise and polluted air. They also create a generally applicable basis for precautionary and reduction measures, provide limit and guideline values and define the specifications for dispersion calculations.

The core of immission control in Germany is the Federal Immission Control Act (BImSchG). In addition to the existing regulations in Germany, IMMI also supports all relevant international calculation regulations. Here you will find an overview. For further information about standard-compliant calculations, please contact our experts Janosch Blaul and Denise Müller directly.

The history of the IMMI forecasting software goes back to the early 80s. The development was driven by the acousticians at Wölfel, a tech company which today has over 100 employees. Their drive lead to the first commercial version of the IMMI software being made available on the market in 1987.

As founding members of the standardization committees for DIN 45687 and ISO 17534, the IMMI team has contributed significantly to the quality standard for immission forecasts that is now established worldwide and which serious products in this field must meet. 

You, our users, play an essential role in the shaping of IMMI. The software as we know it today has taken its current shape due to the daily support we provide our customers – not only the user, but also we learn in the process. The feedback we get is the base for our continuous development. Together with our engineers, an experienced team realizes our high standards of service quality, user-friendliness, and being up-to-date.
