SoundPLAN Graphic

The SoundPLAN Graphic Module dramatically change the way SoundPLAN results are graphically presented.  The Graphic Module allows an object oriented generation of maps with different types of results or graphic information (i.e. digital site pictures, vertical and horizontal noise contour, air pollution maps). 

The attached Park_Noise.JPG file shows an example map generated with the current SoundPLAN Wins Graphic Version 5.0.  The input data consists of 2 situation (Analysis, Prognosis) and the results from two grid noise calculation (horizontal) and two cross sectional calculations (vertical).

The map is called Park_Noise.  This project is a demo amusement park.  The main source entered in the acoustical model include a roller coaster (line source - 3200 ft), two outside theaters (40 loudspeakers), loudspeakers along a parade route (60), buildings within the park (13) and buildings in the residential area (40).

The Park Noise Map comprises 5 smaller maps:

1)    Analysis w/o Noise Control Main sources are a roller coaster, two theater audio systems and the loudspeaker along the parade route.
2)    Prognosis w/ Noise Control Roller coaster emission was reduced by 5 dB and the planner entered two 20 ft  noise barriers. 
3)    Difference w/o vs. w/ Noise Control  The 20 ft noise barrier are mainly reducing the noise for a small shadow zone. The difference map indicates that the noise levels did not change (white area) in those areas where the noise contributions from the theaters are dominant (South-West).  The elevated noise sources (roller coaster) reduce the overall affect of the noise barriers.  The upper limit for noise reduction is therefore 5 dB.
4)    Cross Sectional Map 1
(Prognosis w/ Noise Control)		 Location of the cross section - see dashed red line in Prognosis MAP w/ Noise Control.  The map show the elevated noise sources, the reflection and the screening effect from buildings. 
5)    Cross Sectional Map 2
(Prognosis w/ Noise Control)		 Location of the cross section - see dashed red line in Prognosis MAP w/ Noise Control.
