In order to improve the chances of recovery of young patients suffering from hypoacusia, it is necessary to conduct hearing diagnostic tests during the first 3 to 6 moths after birth. However, for instance, in rural areas of Mexico where there is little or null access to specialized equipment, it is common to find that patients are not diagnosed until the patients’ diminished hearing capacity has impaired their speech development as well as their and social and school integration. This paper presents the design and construction of the EEG-ITM03 EEG auditory evoked potential data acquisition system intended for diagnostic of hypoacusia. The EEG data acquisition system was tested on 5 healthy young adults and the results were compared to those obtained using a commercial equipment (CADWELL 7200). The results show that the early brain stem evoked potential latencies, related to the hearing process can be detected, even when the system is operated in non-ideal locations for conducting hearing tests. Thus the results suggest that the equipment can be used in clinics without special facilities (i.e. sound proof rooms) as part of routine diagnostic activities.
