Because of its complex study design, the subproject "Specific Effects of Nocturnal Aircraft Noise on Humans" requires scientists from different directions to co-operate.Other studies investigating nocturnal aircraft noise have only examined electro-physiological variables, which didn't allow for an integrative view of the problem. The development of special soft- and hardware enables us to react flexibly to changing requirements in measurement technology and study design.
Aproximately 108 MByte of data are needed per subject each night. In part, these data have to be prepared mathematically to be able to interpret them medically. Therefore, it is necessary to provide software which determines these medically relevant parameters mathematically correctly. The evaluation of the polysomnographically raised data is carried out by experienced physicians who are also responsible for the medical preselection and and the medical support of the volunteers during the study.
Further important variables of the study are the analysis of stress hormones in the urine, which belongs to the field of biochemistry, and the production and evaluation of the questionnaires for the measurement of the subjective perception of the volunteers, which requires psychological as well as statistical authority.
An important condition for obtaining the correct measurement data in the study is of course the use of acoustic playback noises in the sleep facility that are as close to reality as possible in both volume and frequency structure of the aircraft noise. During measurements at volunteers' homes, the noises have to be recorded very exactly on the inside as well as on the outside. Physicists are responsible for this area of the research.
Thus, in order to be able to competently work on the points specified above (among other issues), the following scientists are represented in the Department of Flight Physiology:
