Strategic Noise Maps 2007
Calculation Results / Tabular Evaluations
As required in the “Directive on the Assessment and Management of Environmental Noise”, strategic noise maps graphically represent the noise situation in the following isophone classes:

They form the basis for preparing an overall urban noise reduction plan .
The noise exposure is specified through the following variables:
- Tabular data about the estimated number of persons living in areas located within the isophone bands according to Fig. 2. Figures should be rounded up or down to the next hundredth place.
- Tabular data about noise-exposed areas as well as the estimated number of dwellings, schools and hospitals in these areas for the following LDEN values: LDEN > 55 dB(A), LDEN > 65 dB(A), LDEN > 75 dB(A).
