Noise
Noise is what others do!
Noise is unwanted, disturbing sound. This definition already suggests how difficult it is to evaluate this phenomenon. On the one hand, noise is unwanted and disturbing, so a purely subjective evaluation. On the other hand, sound is a physical quantity that can be measured with a measuring device. A sound can be very loud and still be perceived as pleasant. But it can also be very quiet, and still be noise.
The Noise Section of the Environmental Protection Department is responsible for enforcing the Noise Ordinance. We work every day to reduce the number of people in Liechtenstein who are exposed to noise. We are happy to take care of the noise problems of the Liechtenstein population and, if possible, offer assistance with all types of noise. This includes, for example, road noise, industrial and commercial noise, or construction site noise.

Public announcement of the public display of the noise remediation concept of ÖBB Infrastruktur AG and the audit report of the Office for the Environment (Art. 16 Para. 2 Public Announcement Act, LGBl. 1985 No. 41)
ÖBB Infrastruktur AG was required to remediate the railroad facility with regard to the noise emissions emanating from it. A noise remediation concept was submitted for the purpose of noise remediation, setting out the measures to be implemented to limit noise emissions. The noise remediation concept was reviewed by the Office for the Environment and the result was recorded in a review report.
It is possible to submit a statement to the Office for the Environment until the 10th March 2023. Persons whose interests are affected by the remediation order to be made may submit an application for party status to the Office for the Environment (Art. 31 para. 5 LVG). The substantiated application must also be submitted to the Office for the Environment by March 10, 2023. The Office for the Environment will subsequently decide on the application.
Noise pollution register as of 2017
In 2010, as part of the environmental protection legislation, the Office for the Environment compiled the first noise pollution cadastre for the railroad line from the customs office in Schaanwald to the Rhine bridge in Schaan. The cadastre was updated in 2018 (as of 2017). The calculation method is again based on the Swiss specifications.
The main results can be summarized as follows: At 35 (previously 89) objects is an exceedance of the immission limit. These are 21 (so far 44) residential, office or commercial buildings and 14 (so far 45) plots not yet built over. The alarm value is not reached or exceeded in any of the recorded objects.
The decrease in the number of properties affected by an immission limit exceedance is mainly due to three causes:
- In recent years, the rolling stock of freight trains has been continuously renovated and a significant part of the cast iron brake pads replaced by composite brake pads.
- The calculation method has been refined in the meantime, i.e. the individual noise-causing components are mapped more accurately.
- The volume of traffic, especially service and freight trains, has decreased.

Road noise
Noise pollution register as of 2015
The Office for the Environment has compiled a noise pollution cadastre for roads in Liechtenstein based on environmental legislation. This represents the noise pollution in the area of influence of the roads and is based on the status as of December 31, 2014. The entire cadastre includes a technical report as well as maps and tables.
The main results can be summarized as follows:
- During the day, between 6 a.m. and 10 p.m., about 6300 people in Liechtenstein are affected by harmful or annoying road traffic noise. This means these people are affected by a noise level of 60 dB(A) or more.
- During the night, i.e. between 10 pm and 6 am, about 4100 people are affected by harmful or annoying road traffic noise. That is, these people are affected by a noise level of 50 dB(A) or more.
If one considers the assigned sensitivity levels, it can be determined whether a limit value is exceeded. This results in the following figures:
- In 1170 buildings there is an exceedance of the immission limit
- The alarm value is reached in 69 buildings

Noise register Heliport Balzers
Noise pollution register Heliport Balzers - as of 2010
As part of the environmental legislation, the Office for Environmental Protection compiled a noise pollution cadastre for the heliport in Balzers. The cadastre represents the noise pollution in the area of influence of the heliport and is based on the status 2010. The entire cadastre includes a technical report as well as maps and tables. This can be viewed by appointment (+423 236 61 85) at the Office for the Environment.
The main results can be summarized as follows:
- In the assessment of the noise immission of the heliport Balzers according to Annex 5 of the Noise Abatement Ordinance (LSV) is primarily the impact of the maximum level Lmax authoritative.
- It is determined that in 2010 the immission limits according to Annex 5 Noise Abatement Ordinance (LSV) are met.
- There is no need for remediation according to Art. 14 Noise Abatement Ordinance (LSV) for the heliport Balzers.
