Characteristically, aircraft noise causes short, but high peak levels, which can lead to sleep disorders of residents in the vicinity of airports. The aircraft noise module provides the user interface and the range of functions of the other IMMI modules. IMMI complies with the requirements of the German Federal Environmental Agency for programs for the calculation of noise protection areas at airports according to ECAC.CEAC.Doc. 29.
