MOUS_ICO Menu: Noise > Reports
There are several options for printing out calculation results and input data. The following examples show typical printouts:
Report of type Overview
Report of type Specified pr. road
Report of type All details
Alternative - Select what calculation alternative to print out.
Format - There are four different formats available:
Windows text file format
DOS text file format
Semi-colon delimited format, using a comma as the decimal marker (53.1)
Semi-colon delimited format, using a dot as the decimal marker (53,1)
Options 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 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, 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 of 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.
