The purpose of the Newborn Hearing Screening Program is to achieve early. Identification and appropriate intervention for hearing loss. Hearing aids are the most frequent intervention for deafness. Paediatric specific clinical protocols for fitting hearing aids always recommend accurate characterisation of hearing thresholds in newborns. In this sense, electrophysiological procedures are specially indicated in determined hearing sensibility from the first age of life since it is an objective and reliable procedure. 20 normal hearing subject and 17 hearing loss subjects participated in this study. Auditory Steady State Responses (ASSR) were obtained from all of them. Hearing aid fitting was established from the electrophysiological responses. Dynamic range, gain, compression ratio and maximum output of the hearing aid were obtained from the intensity amplitude function of the ASSR. The procedure discussed in this study is specially indicated in newborns and very young children in which other test are not suitable.
