1) For apartment buildings, the number of apartments with measures is counted.
In noise remediation, a single-family house is equivalent to two apartments.
2) A line is considered to be noise remediated even if individual residents do not take advantage of offers to remediate their homes.
The fluctuations in the figures for noise barriers completed and homes with passive measures are due to the annual changes in our construction intensity as well as the project-specific features taken into account in the respective noise expert assessment. These include building density, topography and proximity to tracks and rail traffic.
The sections of track exposed to noise are summarized in the overall noise remediation concept and prioritized according to the degree to which they are affected. The determination of the affected areas as well as the dimensioning and implementation of our noise remediation measures are carried out mathematically with the help of noise expert assessments according to the emissions protection legislation evaluation. This means that a section of track is counted as noise remediated even if individual local residents have not taken advantage of noise remediation offers for their homes.
