The recording of auditory evoked responses (AER) is used in hospitals and
clinics worldwide for hearing impairments detection and threshold estimation,
and in research centers to understand and model the mechanisms involved in
the process of hearing. This paper describes a high-performance, flexible, and
inexpensive AER recording system. A full description of the hardware and
software modules that compose the AER recording system is provided in this
article. The performance of this system is evaluated by five experiments with
both real and artificially synthesized auditory brainstem response (ABR) and
middle latency response (MLR) signals at different intensity levels and
stimulation rates. The results of this study point out that the flexibility of the
described system is appropriate to record AER signals in several recording
conditions.
