[Temporary threshold shift after nuclear magnetic resonance tomography].


The third-octave band levels of the noises produced in a MR-imager (1.0 Tesla Magneton, Siemens) were measured. Corresponding sounds presented through earphones have been used in simulation experiments to produce in normal-hearing listeners a temporary threshold shift lasting several minutes. These effects could be verified objectively using otoacoustic emissions. The consequences especially for patients with already impaired hearing are discussed: ear protection is strongly recommended.
