For more than 20 years, service providers, authorities and industrial companies have been relying on IMMI as one of the leading software tools in the field of immission control. IMMI is a software package for the calculation of sound propagation outdoors, noise exposure in workrooms and propagation of air pollutants.
The history of the IMMI prognosis software dates back to the early 1980s. The first commercially available IMMI software was launched in 1987 by Wölfel acoustic engineers – a technology company which has over 100 employees today.
In cooperation with other acoustic engineers and software manufacturers in Germany, the IMMI team has played an important role in the worldwide establishment of the quality standard of immission prognosis that is common today. As founding members of the standards committees for DIN 45687 and ISO 17534, they have made a major contribution to the quality standard that serious products in this field have to meet.
