IMMI – The Software Solution for Noise

"For almost 25 years now, the IMMI software package has been an extremely useful and helpful support for me in the computer-aided solution of a wide range of sound-related problems. It also fills me with pride to see that a few of my suggestions have been incorporated into IMMI. All the while you and your colleagues have been helpful not only to me, but to all IMMI users with questions and needs".

"We have been using IMMI since 2000. Before purchasing, we compared all relevant products on the market. The decision to purchase IMMI was based on the very logical setup and technically clear program operation. We also appreciate the competent, quick and effective problem solving via hotline inquiries – definitely a big plus for Wölfel. To summarize: IMMI – We would definitely go for it again."

Magistrate of the City of Klagenfurt am Wörthersee (Department of Environmental Protection)

“We frequently use the IMMI model to predict the sound pressure level effect on the nearest houses to new industrial activities, crushers, gas engines, ...  Afterwards we always take measurements to check the results. The IMMI model is well suited to make these predictions (in other words the measured sound pressure levels are almost equal to the calculated sound pressure levels).”

“We use IMMI to evaluate the effectiveness of noise barriers where the possibility to import a wide range of input data is necessary. The simulations made in IMMI are presented very clearly and are visually appealing. This means the results can be understood by both professionals and people who are new to the subject. The user friendly interface is easy to work with and allows for a fast learning curve for new users.”
