Ambient data:

Ambient conditions are defined by the land and atmospheric conditions in the vicinity of the pollutant emission. The Ambient data Menu lists: terrain and topographic lines.

Terrain.- This command is to draw topographical lines. If you click this command, the next dialog box is shown

 

 

This window is to determine the reduction of sound with distance. It is often used to describe the change in sound level as one moves toward or away from a sound source. Attenuation coefficient can describe the reduction of sound  per unit distance.

Topographic lines.- This command is to draw topographical lines. If you click this command, the next dialog box is shown:

 

 

 

Six different noise sources in the XZ plane considering topographic lines. It is shown colour gradient.

 

Noise map in the XZ plane for three sources using noise isolines.

 

 

software · noise mapping

 

Noise mapping: Ambient conditions can be defined by the land and atmospheric conditions in the vicinity of the pollutant sources. The aircraft noise

can be simulated through this software.
