INVESTIGATION OF PERCEPTION AT INFRASOUND FRE- QUENCIES BY FUNCTIONAL MAGNETIC RESONANCE IM- AGING (FMRI) AND MAGNETOENCEPHALOGRAPHY (MEG)

Currently the emission of infrasound at work places and in daily life is becoming more pronounced because of an increasing number of sources as wind parks, pumps of renewable energy systems or the permanently increasing road traffic. The evaluation of also increasing complaints is accompanied with a still limited understanding about the perception mechanisms at these frequencies hindering the development of efficient assessment methods or the definition of exposure limits. New insight into mechanisms of perception can be expected from neuroimaging techniques providing objective information about noise processing in the brain.
