The area of noise research deals with the sources of noise and the effects of noise on human beings. Aurally-accurate assessment of noise proves to be difficult. Not only the complex structure of noise and noise sources as well as the context and situation when noise occurs affects the noise exposure and perception of a single person.

Well-known standardized strain parameters, such as A-weighted sound pressure level in dB(A), do not allow any conclusions with regard to the actually experienced noise strain or their long-term effects.

The focus of our work are the effects of noise on auditive attention and hearing process of children and adults. Research in preschools and primary schools have shown that it is important to use a measuring technologies especially developed for children to assess, record and to evaluate noise for children. Former research has already shown, that children differs from adults significantly (Binaural Technology (artificial heads for children)).

A further aspect of our research is the aurally-accurate reproduction of noise in listening experiments for children to achieve realistic noise scenes from the daily life of children.
