Four years of experience with the hearing tests for babies MIRA (electrical registration of sucking, breathing and localisation reactions, respectively, due to acoustic stimuli with following evaluation of the curves) and biofeedback (1 1/2 years of experience, frequency modulation of the stimulus by the sucking activity and thus examination of the interaction between articulation and hearing) show different kinds of influence on the threshold determination. These are, in the first year of life, influences of a physical nature (room acoustics, audiometric apparatus and activity transducers) and of organisation and action (taking care of the babies, problems arising from simultaneous action and observation), as well as of different weighting of the number of reactions. These are compared with each other in respect of the reactions they provoke, rated individually, and discussed.
