On “Noise Awareness Day” on April 29, 2026, attention will be drawn to the effects of noise on our health.
This is because noise is not only annoying and a cause of sleep disturbances—its effects on our health go far beyond that: cardiovascular and metabolic diseases, mental health issues, and even premature deaths can be attributed to noise.
Compared to other environmental health hazards, traffic noise is one of the most significant health risks in Europe—second only to air pollution.

Railway noise in Liechtenstein

As part of environmental protection legislation, the Office of the Environment created a noise pollution register for the first time in 2010 for the railway line from the Schaanwald customs office to the Rhine bridge in Schaan. The calculations are based on Swiss specifications. The register was updated in 2018 (as of 2017). In 2021, a noise remediation concept was further developed by ÖBB Infrastruktur AG.

Since 2010, noise pollution along the route has been continuously reduced. While 89 properties were still affected by exceedances of the immission limits in 2010, this number had fallen to 35 by 2017. With the implementation of the noise remediation concept from 2021, the immission limits will be complied with along the entire ÖBB route between Feldkirch and Buchs. The main reasons for this are technical improvements and the refurbishment of rolling stock. Particularly relevant is the ban on freight cars with gray cast iron brake shoes, which used to cause high noise emissions. These have been banned in Switzerland since 2020 and will also be banned in Liechtenstein from 2023.

In addition to the ban on gray cast iron brake shoes, the number of trains plays a decisive role in compliance with the limits. The traffic forecasts contained in the noise remediation concept are reviewed annually by the Office for the Environment. The evaluations for the years 2021 to 2025 show that the forecasts have been met. This means that there are currently no exceedances.

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 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.
