NOISE is a tool that allows
consultation of the noise exposure data and noise contour maps reported by EU Member States
and EEA member countries in accordance with the strategic noise maps
required by the Environmental Noise Directive.
The map-viewer enables the user to locate in Europe the main noise sources at various scales of
geographical representation; to look up noise exposure data for these sources; consult changes on noise exposure
occuring between 2007 and 2012 in agglomerations and major airports and download the data corresponding to strategic
noise maps as reported to the Commission and EEA. It also allows the visualisation of noise contour maps at country
level or at a more detailed scale for those countries that provided them in a usable Shapefile format.
You will also find a list of Frequently Asked Questions with answers that will hopefully assist your
use of NOISE here.
Content of NOISE
NOISE application contains two main pieces of information:
Noise exposure information with:
- A map with its respective legend (in the “Legend” widget window) showing the noise exposure
data relative to the noise source selected (for 2007 and for 2012).
- In case a country is not displayed when selecting Major Roads or Major Railways information,
that means that the information being delivered is not covering the complete set of noise sources
expected (e.g. only information on noise exposure corresponding to lower thresholds was delivered,
and therefore, the information is not comparable with the rest of Member States). For those Member
States that this completeness information is not specified, it is assumed that the number of people
exposed being reported covers the complete road and rail networks with the thresholds specified by
the Environmental Noise Directive.
A graph (in the “Exposure statistics” widget window) showing the total number or percentage
of people exposed to the different decibel bands by a noise source. The data relative to the map
is indicated by a shadowed area on the graph. The graph is dependent upon the geographical
scale selected in the bottom bar of the viewer.
Information on noise exposure in the map is available from European to local scale.
The “Statistics” widget window will only be uploaded or updated
when a specific year, a particular noise source and a level of scale is selected from one of the menu boxes.
Changes on noise exposure information with:
- A map with its respective legend displaying changes on population exposure (total change and percentage
of change) between 2007 and 2012 in agglomerations and for major airports.
A graph (in the “Exposure statistics” widget window) showing the total number of people exposed per noise
band in 2007 and in 2012, and the overall difference.
Information on changes on noise exposure information only considers those entities (agglomerations and major airports)
having two reporting dates, 2007 and 2012. The rest of entities are shown as data on changes not available
or not applicable depending on each specific case.
- Noise contour maps:
- A local scale map which illustrates noise contours for Lden and
Lnight, if provided by the country in a usable Shapefile format and
with a correct geographic projection
The navigation tools enable panning and zooming in and out from
European scale to a country or to a more detailed scale in both cases:
when visualizing noise exposure information and also, noise contour
maps. Whereas using the boxes in the bottom bar menu, the choices will
guide the user towards a specific map view and scale.
It is not the intention of the current application to show noise
contour maps at European level, they will only be shown at local level
(for agglomerations and airports) and at national level (in the case of
major roads and major railways noise contour maps) if the information is

How do I get started to consult NOISE exposure data?
How to proceed:
- STEP 1: In order to visualise the noise exposure data in
the viewer you should select “Noise exposure data” in the tab of the
bottom bar of the viewer (by default, this information will be the one
- STEP 2: Then, you should select the year to display noise exposure data (2007, 2012 or the changes 2007 — 2012).
STEP 3: You should also select a source from the “Noise source” widget window, located at the top
right hand side of the screen.
Next, you should select a noise indicator from the same tab (Lden and Lnight)
and if you would like to consult "Total" or "Relative" values on people exposed to noise (European scale is the default display).
In case you would like to consult changes 2007 - 2012, you will be able to select the noise indicator
(Lden and Lnight)
and the noise source inside agglomerations. Then you will be able to see in the
map the total net change and the percentage of change of people exposed above 55 dB
Lden or above above 50 dB Lnight.
- It is only possible to visualise a single value on noise exposure data each time you make
a selection, due to the manner in which data has been reported in accordance with the END.
- STEP 4: In order to update the statistics displayed into a more detailed geographical scale
(e.g. at country level), it will be necessary to select the country or the more detailed information from the boxes located at
the bottom bar of the viewer. The zooming and panning functions will allow you to browse through the map, but the use of the
navigation tools will not update the statistics displayed.
Once the 4 steps accomplished, the map, the exposure
statistics widget window and the legend widget window will be uploaded (or updated)
with the selected information.
|What can you find in each section?|
- Noise exposure data is shown in the map at European, national and
- Exposure to Major Roads and to Major Railways can be only
detailed at national level, considering the requirements of the END and how the information is provided.
- Statistical information referring to local noise sources (i.e.
agglomeration or major airport) can be consulted by selecting a single entity from the box
"More detailed information" at the bottom bar. You
can always go back to the national scale by selecting "Back to country
- Due to the way in which noise exposure data has been reported, it is not yet
possible to view figures for the overall noise impact from all sources
- Links to national noise maps and map-viewers can be accessed here. Responsibility for the maintenance of the web sites provided rests with the member states and member countries.
