New system for neonatal hearing screening based on auditory steady state responses

NEURONIC-A 6.0 is a system for objective detection of hearing loss by means of the recording and analysis of auditory steady state responses. The system generates digitally Amplitude Modulated tones of different frequencies, allowing the mix of these and the simultaneous presentation through different transducers (earphone and bone vibrator) at different intensities. The system also includes a procedure for artefacts rejection based on the trajectory of variation of the residual noise through time and quantitative indicators or statistics, calculated in the frequency domain, to control the acquisition of the response process and detect automatically the presence or absence of the same. The whole working procedure is automated, which means that once the recording has started, a final result can be obtained in binary form (pass or fail) without the intervention of the examiner.
