Klagenfurt noise map: how loud is it at your address?

Enter your address and you get the official noise levels for exactly that spot: by day and by night, where the noise comes from and whether it exceeds the thresholds. One thing up front, because it matters more here than in any other city we cover: Klagenfurt has 105,734 inhabitants and is therefore above the threshold at which the EU requires area-wide mapping, yet it is still not a designated agglomeration. Only the major transport routes were surveyed. Of 6,561 inhabited locations in this market, 725 carry a zone at all, that is 11 per cent, the thinnest figure across all seven markets. Where nothing is coloured in, that usually does not mean quiet here, it means not surveyed. The good news comes further down: the city itself keeps a denser map.

How to read the map

The map shows the continuous sound level in zones of 5 decibels each: once averaged over the whole day (Lden, weighting evening and night more heavily) and once for the night alone (Lnight, 10 pm to 6 am). Green here means: below the mapping threshold of 55 dB by day or 45 dB at night, OR outside the surveyed area. Telling those two meanings apart is the key exercise in Klagenfurt, because the second case dominates.

below 55 dB

Quiet or not surveyed. Neuer Platz, Alter Platz, the Kreuzbergl and the Europapark carry no zone by day or night. In the Innere Stadt, the Viktringer Vorstadt and in Keutschach am See, Liebenfels and Maria Wörth the map is completely empty, although 1,111 inhabited locations lie there. Green says nothing in those places.

55 to 64 dB

Audible but ordinary. This band covers the main station at 55 to 59 dB and the airport surroundings at 60 to 64 dB, the latter from three sources at once: air, road and motorway.

65 to 74 dB

Loud. This is the band of Villacher Straße, the Südring in Waidmannsdorf, Lastenstraße and the Südbahngürtel. On Lastenstraße the road and rail zones overlap. Soundproof windows make the difference here, and the city subsidises them.

above 75 dB

Very loud, the top band of the scale. Measured at two places: on the A2 motorway near St. Peter, which is also in the top band at night at over 70 dB, and on the Südring at St. Ruprecht.

Rule of thumb: most people perceive 10 dB more as twice as loud. And the night counts for more than the day, Lnight being the more important figure for sleep. That matters especially on the Südring and the A2, both of which sit in the top or second-highest band at night as well.

When does it officially count as too loud?

Two figures help with the ranking. The WHO recommends below 53 dB by day and below 45 dB at night for road traffic. Austria additionally sets thresholds for action planning in the federal environmental noise act, and they depend on the source.

Rail noise has the mildest daytime value at 70 dB, industrial noise the strictest at 55 dB. That is not arbitrary: a permanent plant noise counts as more disturbing than a train passing by. For Klagenfurt this means two things. The Südbahngürtel sits at 70 to 74 dB, exactly at the rail threshold, while the main station at 55 to 59 dB is far below it. And the airport stays below the 65 dB air traffic threshold at 60 to 64 dB, even though it is the only source in this market producing its own aircraft zone by day and by night. If a threshold is exceeded, the responsible bodies examine measures: the state of Carinthia through its action plan, the ÖBB for the railway, ASFINAG for the A2 and the city for its own roads. No legal entitlement to a specific measure follows from this. The analysis above ranks your address against exactly these values and takes the strictest one where several sources overlap.

What the map can and cannot do

Above 100,000 inhabitants and still not an agglomeration

The EU environmental noise directive names 100,000 inhabitants as the threshold for area-wide mapping, but designation is up to the member state. Austria has designated exactly five agglomerations: Vienna, Graz, Linz, Salzburg and Innsbruck. We queried the official layer ourselves in both mapping rounds, 2020 and 2025: Klagenfurt returns no hit, Innsbruck does. With 105,734 inhabitants Klagenfurt is therefore the largest Austrian city without area-wide mapping.

Green here usually means “not surveyed”

Of 6,561 inhabited locations in this market, 725 carry an official zone, that is 11 per cent. In our other six markets it is 17 to 40 per cent. Five regions are completely empty, among them the historic centre itself. No zone there is no statement about quiet.

The city has a denser map than the EU

The municipal authority keeps its own noise immission cadastre, and it covers what the EU map leaves out here: municipal and state roads in addition to the motorway, plus the Südbahn, the Rosental S-Bahn, the Wolfsberg line and the airport. It distinguishes day (6 am to 7 pm), evening (7 pm to 10 pm) and night (10 pm to 6 am). Data basis: traffic model 2014, rail and air 2015/2016. If the map above stays silent for your address, that is the second opinion you are looking for.

The Südring and the A2 are in the top band

At both places the official map shows Lden above 75 dB, and on the A2 near St. Peter above 70 dB at night as well. These are the loudest values in the whole market, far above the 60 dB threshold for road and motorway noise.

Aircraft noise is mapped here, unlike in St. Pölten

Klagenfurt Airport produces its own aircraft zone, Lden 60 to 64 and Lnight 50 to 54 dB in the terminal area. Both lie below the aircraft noise thresholds of 65 and 55 dB. The municipal cadastre explicitly excludes helicopter and military movements.

Industrial noise is not surveyed

Permit-bound industrial plants (IPPC) are mapped only in the five designated agglomerations. No industrial zone therefore exists for Klagenfurt. That does not mean there is no plant noise, only that nobody has surveyed it across the area.

Traffic only, not neighbours

Mapped are road, motorway, rail, air traffic and permit-bound industrial plants. Bars, building sites, neighbours or the guest garden next door do not appear. Those fall under the noise ordinance further down, which in Klagenfurt is unusually specific.

Calculated, not measured

The official map is modelled from traffic data (EU environmental noise directive), not measured at every address. For orientation it is very reliable where a survey took place.

Courtyard versus street side

The value applies to the grid cell. A courtyard-facing flat on a loud axis can still be quiet, and only the viewing settles that (open the window!).

Address point inside the building

A geocode usually sits in the middle of the house, but the noise zone ends at the façade. If the point itself lies in no zone, the analysis takes the loudest zone within about 15 m, that is the street side, and says so.

Quiet hours in Klagenfurt: what actually applies?

Here Klagenfurt is more precise than most Austrian cities, and considerably more precise than St. Pölten. The basis is the Carinthian state security act, whose section 2 prohibits unreasonably disturbing noise and expressly empowers municipalities in subsection 4 to define their own offences. Klagenfurt has made use of that: the noise protection ordinance of the city council of 23 June 2015, last amended on 21 May 2024, names fixed times.

Noise-generating work in private households, that is hammering, sawing, drilling, mowing, shredding, leaf blowing, chiselling or concrete mixing, is prohibited on working days from Monday to Saturday between 12 noon and 2 pm and between 7 pm and 7 am, and all day on Sundays and public holidays. Leaf blowers and leaf vacuums with a sound power level above 104 dB are prohibited regardless of the time. Breaching this is an administrative offence: up to 218 euros or two weeks of detention.

What else is regulated in Klagenfurt

Loud operation and sport: 10 pm to 6 am

Loud singing, shouting, music-making, the loud operation of technical equipment as well as bowling and ice stock sport are prohibited at night between 10 pm and 6 am (section 5(1)). Outdoor sport shooting has its own times: prohibited between 11 am and 3 pm, between 6 pm and 7 am and on Saturdays, Sundays and public holidays.

Glass recycling: not between 7 pm and 7 am

Throwing waste glass into the collection containers is prohibited in residential areas and near inhabited buildings between 7 pm and 7 am (section 5(3)). A rule many people do not know, and the most avoidable evening noise in residential streets.

Barking animals: not outdoors 7 pm to 7 am

Animals that disturb the night through frequent barking or crowing may not be kept outdoors or in open spaces in residential areas between 7 pm and 7 am (section 3). Agricultural animal husbandry is exempt.

Pool pumps and ultrasonic devices

Pool pumps must be installed with enough sound insulation that they are no longer perceptible at the nearest property boundary even in a quiet setting (section 5(4)). The same applies to ultrasonic pest and animal repellents. That is stricter than a decibel limit, because the yardstick is audibility.

Street music: pedestrian zone only, 10 am to noon and 2 pm to 7 pm

Street music is permitted exclusively in the Klagenfurt pedestrian zone, by at most four people, only between 10 am and noon and between 2 pm and 7 pm, without amplification. The spot must be changed after 30 minutes at the latest, at least 50 metres away. It is not allowed directly in front of house entrances, shop entrances, passages and guest gardens, nor at the Wappenrondeau, the Wörthersee-Mandl or the Trinity column on Alter Platz.

Exempt: work in the public interest

Snow clearing, waste collection and green space maintenance by the city or on its behalf fall outside the ordinance (section 6). Winter service at 5 am is therefore permitted.

Police and the municipal authority are responsible

For unreasonable noise here and now the police are responsible (emergency number 133). For noise from a licensed business, a guest garden or a building site it is the Klagenfurt municipal authority; in the surrounding area the district authority Klagenfurt-Land. For the traffic noise on this map the state of Carinthia is responsible, the ÖBB for the railway and ASFINAG for the A2.

The city subsidises soundproof windows

Anyone living on a municipal road or within the airport catchment can receive a subsidy towards soundproof windows, doors and sound-insulating ventilators. A window counts 3 points, a ventilator 1 point, one point equals 60 euros, at most 20 points per person, that is 1,200 euros, added up over five years. The conditions are an outdoor level above 60 dB by day or above 50 dB at night, determined from the city noise map, a floor area up to 150 m² and a main residence in Klagenfurt. The application must arrive within six months of completion, and there is no legal entitlement. Important: the subsidy covers municipal roads and the airport area, not the A2 and not the railway. ASFINAG and ÖBB are the addresses for those.

Free advice beforehand

The climate and environment department of the municipal authority (Bahnhofstraße 35) offers a free hour of advice from a noise engineering expert: which measure will help in your case, and by how much. Before replacing windows, that is the cheapest hour of the project.

For recurring noise, the building management

For recurring noise, write to the building management with the date and time of each incident. A noise log is the most important evidence if things go further. If noise makes the flat substantially less usable, for instance during months of construction, a rent reduction under section 1096 of the civil code comes into question; the Carinthian chamber of labour and the tenants association advise free of charge.

Despite all these rules there is no decibel limit for neighbourhood noise. Decisions follow what is locally customary and whether the usual use of the flat is substantially impaired (section 364(2) of the civil code). Someone living on Lastenstraße has to accept more than someone in a cul-de-sac in Wölfnitz. Decibel thresholds apply only to the traffic noise on this map, and the 104 dB for leaf blowers is a device rating, not an immission value.

This summary is orientation, not legal advice. And it concerns neighbourhood noise, which the map above does not show: there it is about road, motorway, rail and air.

And aircraft noise?

Unlike in most of our markets it exists here, and it is mapped. Klagenfurt Airport lies in the north of the city near Annabichl, and the official map shows its own aircraft zone around it: Lden 60 to 64 dB in the terminal area. Road and motorway noise overlap there as well, making it the only place in this market where three sources are mapped at once.

Air traffic has a threshold 5 dB higher than road traffic, that is 65 dB by day and 55 dB at night. The measured 60 to 64 dB stay below it. More important for the ranking is the metric itself: Lden averages over the entire year. A single approach is loud for about a minute and disappears in the annual mean. Anyone who wants to know how a single take-off feels has to go there.

Worth knowing when searching in Annabichl, Welzenegg and St. Peter: the municipal noise immission cadastre expressly excludes helicopter and military movements from its calculation. And the city soundproofing subsidy names the airport area explicitly as an eligible case, alongside municipal roads. Anyone replacing a window there should ask first.

For the night the map shows Lnight 50 to 54 dB at the airport, likewise below the 55 dB threshold. A night flight ban is not something this map regulates, ask the airport itself about that.
