In this study, an ABR measurement system, which is used for determining auditory functional loss, threshold of hearing and brainstem neurologic disorders is designed and implemented. The system consists of four main stages. In the first stage, bioelectrical signals which occur after the transmission of stimulus signals are accumulated from skull skin by using electrodes. In the second stage, the obtained signals are transferred to analog module of the system and in this module, amplification and filtering processes are performed the analog signals. In the third stage, the analog signals are digitized by using the TMS320C6713 module and passed through several digital signal processing functions. In the last stage, demonstration and evaluation of the measurement result is carried out by the user interface software which is used for control of the system. Finally, an advanced ABR measurement system which is user-friendly and accessible to all phases of hardware and software and open to development for academic purpose, is designed and implemented.
