Central model parameters form

Central model parameters for the propagation calculation.

Project title

Title for reports and illustrations.


Deviating from the usually defined downwind average level, if a statement about the expected long term level (taking account of varying winds) is to be made, the reduction can be considered with sm as the distance from the source to the receiver (in m) (ISO 9613-2 (VDI 2714), page 9). see 4.1 Propagation calculation.


According to requirements, the emission level for discrete noise sources will be displayed either A-weighted and/or in the frequency band.

Vegetation/Development attenuation

see 4.6 Vegetation/Development attenuation (Ddg)

Development height [m]

Primary frequency [Hz]

see 4.4 Absorption of sound by the atmosphere (Dl)

Air temperature [°C]

see 4.4 Absorption of sound by the atmosphere (Dl)

Humidity [%]

Ground attenuation thru: Dispersion/Reflection

For reflection sources, the sound power will be reduced in accordance with the specified reflection losses for the ground and for each obstacle. A level can be entered or a spectrum can be selected here.

Variant 1 ... 3

Interprete as Day/Evening/Night and calculate Lden

Calculation of the day-evening-night level Lden according to the DIRECTIVE 2002/49/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 25 June 2002 relating to the assessment and management of environmental noise.
