Resumen:
Conventional audiometry techniques explore the auditory apparatus through a conscious and voluntary response of the patient. But in some particular cases (for example in babies or disabled people) this response is not always reliable, or feasible. Due to this possibility, it was necessary to develop a new method that allows obtaining information from the auditory system and its pathway, without the collaboration of the patient. Thus, objective methods have been developed that explore the sensory system, but based on the study of some reflex or an unconscious response of the subject. So far, several electrophysiological techniques have been developed to perform objective audiometries detailed by frequencies. The most recent and promising technique in the audiometric field is the one that employs Steady-State Evoked Potential (SSEP) or also Auditory Steady-State Response (ASSR).In this paper it is described a system that detect hearing loss at different frequencies by using a novel technique, which consists on the use of multiple frequencies and multiple amplitudes of stimulation, and the corresponding recording o Steady-State Evoked Potential SSEP
