Point source data I:

This is a point source. The source size is small if we compare it with the size of the area in which we are simulating (point source). If you click this button, the next dialog box is shown:

 

The necessary data is:

External source/internal source/airport options: This is the External/internal/airport option. External means a noise source placed out of a building (for example, a vehicle engine).

External surface (m2): In the internal source option, this is the external area of the building.

Noise insulation (dB): In the internal source option, this is the noise insulation value.

Noise power (dB): This is the noise power at source position in decibels.

Airport options: We have two options: An aircraft landing/taking off at 300m or Daily average (number of airport operations in a day).

 

 

Noise map for a road. We have used isolines.

 

 

Noise map in the XZ plane for a line source. Colour gradient has been used.

 

noise attenuation barriers

 

Noise attenuation barriers: The effect of barriers can be simulated through CUSTIC software. It can be also calculated in the case of train noise and construction noise. Noise maps can be easily obtained using this tool.
