The map of the month visualizes the maximum noise exposure at building level for Berlin Kreuzberg. This information is part of the building info project: Even in busy Kreuzberg, many of the buildings are not within the noisy areas (grey buildings on the map), which does not mean that it is really quiet there. The underlying noise exposure figures are mostly model-based and only consider the predefined noise sources (main roads, railroad lines, industrial plants and airports). Temporary noise sources such as construction sites, events, or even the background noise in side streets are not considered.
