MOUS_ICO Menu: Noise > Reports…
There are several options for printing out calculation results and input data. The following examples show typical printouts:
Alternative
Select what calculation alternative to print out.
Format
There are four different formats available:
-
Windows text file format
-
DOS text file format
-
Semicolon delimited format, using a comma as the decimal marker (53.1)
-
Semicolon delimited format, using a dot as the decimal marker (53,1)
Option 1 and 2 generate a readable report, while options 3 and 4 generate a semicolon-delimited format that can be imported into a spreadsheet. Using a spreadsheet gives many possibilities as to making various presentations of the calculation results, e.g. making a graph with a profile along the horizontal axis and noise levels along the vertical axis (select All details during the calculation to generate enough data). Such a graph will give a clear view as to which road sections contribute to high noise levels.
Another spreadsheet option is using calculation points with names along the horizontal axis and noise levels along the vertical axis. This gives a good schematic picture of the noise levels for residents in the area, both before and after noise barrier measures.
All report types are followed by small summary reports. These sum up how many persons are exposed to different noise levels. The numbers are calculated by looking at the highest noise value for each building and the number of persons in the building. In the first report, the numbers are written with one decimal without further rounding. In the second, the rounding follows the directive 2002/49/EC where it is specified that the numbers should be rounded upwards to the nearest 100 persons. So 49→0, while 51→100.
The noise intervals should be interpreted so that “70-74” means the mathematical interval [70-75). This consists of all numbers from and including 70.0 up to, but excluding 75.0.
Include input data
Includes input data in the report, but only available if the last calculation had the option Save details on in vnnp_noisealternatives.
Summary
Generates a report with overall noise levels for all calculation points.
List separately for each road
Generates a report that shows the contribution from each road, including total noise levels. This report is only available if the last calculation had the option Save details on in vnnp_noisealternatives.
All details
Generates a report with all details. This report is only available if the last calculation had the option Save details on in vnnp_noisealternatives.
The report will start on the lowest level of calculation parameters, listing an individual noise source with each connected calculation point. This is repeated for all noise sources on all roads for each calculation point. Sums are accumulated for each noise source, for each road, etc. This kind of report generates a lot of data, so be restrictive about how many calculation points to include each time. The following parameters are printed (in order from left to right, the headings are somewhat scrambled in some formats):
-
PROFILE: Station no. on the road where the noise source is located
-
Stl: Noise source output value, incl. correction and length of the section
-
dist: Distance between a noise source and calculation point
-
dista: Distance attenuation
-
%hardgr, first value: Percentage hard ground between source and barrier (or calculation point if no barrier)
-
%hardgr, second value: Percentage hard ground between barrier and calculation point
-
rd-bar-cp, first value: Distance between noise source and barrier
-
rd-bar-cp, second value: Distance between barrier and calculation point
-
barh: Noise barrier height, as measured on the resident side from ground level to top
-
ebarh: Effective noise barrier height, the barrier's height above the sightline between a noise source and calculation point
-
bara: Noise barrier attenuation
-
barht, first value: Noise barrier thickness
-
barht, second value: Noise barrier thickness correction factor
-
gradient, first value: Road gradient, specified in 0/00
-
gradient, second value: Road gradient attenuation
-
grd: Terrain surface attenuation
-
corr: Sum of all attenuations for the profile
-
Lequ: Equivalent noise level
-
Lmax: Maximum noise level
-
Lden: Lden
-
Lnight: Equivalent noise level for the night period
-
Lref: Reflection contribution
Screen
Generates an “AutoCAD help file” (old AutoCAD style) and displays this on the screen in a dialog box (after selecting Write). When the dialog box is closed, the content is deleted.
File
Write the report to a file.
Select file…
Opens a standard AutoCAD dialog box to input a file name.
File name
The selected file name is displayed in this field. One can also choose to enter the file name directly in this field.
Write
Generates the report and closes the dialog box.
Cancel
Closes the dialog box without generating a report.
