Device for determining acoustically evoked brainstem potentials and cushion therefor

摘要

The invention relates to a device for determining acoustically evoked brain potentials in objective audiometry from electrodes applied to the head of a subject, where the device comprises a plurality of electrodes, i.e. at least one pickup electrode and a reference electrode, to be applied at different points of the head, where the electrodes are mounted on a structure in fixed positions in relation to each other, where the structure comprises at least one flexible cushion abutting the head of the subject around an ear, where the pickup electrode and the reference electrode are integrated in the flexible cushion.
