This invention relates to the apparatus for the objective detection of auditive disorders, by recording arising potentials of a steady state with simultaneous acoustic stimulation via the bones or the airway to be used in newborns. The apparatus comprises the necessary means for the independent generation of two different sound stimuli presented to the subject simultaneously via osseous, and airway electroacoustic transducers, the synchronous recording of the cerebral electrical activity of the subject, the continuous evaluation of the contact of the electrodes, the interactive measurement of the levels of ambient noise, and the wireless digital transmission of the bioelectric activity towards a computer.
