RADIUS study
Noise and sounds in everyday life and their effects examined individually

The effects can be very diverse and they are constantly changing. New sources with new properties are added, circumstances and conditions change. Investigations into how these new conditions affect people are an important area of research in order to assess exposure and develop countermeasures.
The RADIUS study conducted by the Physikalisch-Technische Bundesanstalt is investigating whether and to what extent different types of noise affect people's well-being in everyday life. The study is now also to be carried out in parts of Wolfsburg. To this end, the Physikalisch-Technische Bundesanstalt will be contacting some randomly selected residents of the districts of Ehmen, Fallersleben, Mörse and Sülfeld aged between 18 and 75 in writing at the end of February/beginning of March. Further information can be found in the following text or on the website of the Physikalisch-Technische Bundesanstalt:
RADIUS study
As part of the study, not only audible noises (hearing noise) are recorded, but also so-called "infrasound". Infrasound comprises particularly low frequencies (below 20 Hz), which we often do not consciously hear, but which can sometimes be perceived as a vibration or roar. This is generated naturally (e.g. by the wind) or by large machines (e.g. wind turbines).
Another special feature of the study is that it records various data in a person's everyday environment over a longer period of time and thus provides a realistic picture of individual situations directly on site. It therefore goes beyond the studies often carried out under precisely controlled conditions in the laboratory or test room.
For this purpose, a specially developed, pocket-sized sound measuring device records the frequency components of the ambient sound, which are stored in such a way that no conclusions can be drawn about spoken language. In combination with short everyday queries via an app on a provided smartphone and the results of sensors for recording pulse and skin conductivity, the individual sound exposure can be determined throughout the day. These sensors are integrated into a wristband that is barely noticeable and causes little disturbance.
The study is being conducted with test subjects who were randomly selected according to predetermined criteria such as place of residence. Unfortunately, it is therefore not possible to actively apply to take part.
The results of this study provide valuable insights for science and society and help to better understand health and quality of life in connection with noise and infrasound emissions.
