Development of an Auto ABLB Test Software

ABLB(Alternate Binaural Loudness Balance) test is one of the medical assessments to diagnose detailed lesion of sensory-neural hearing loss based on a recruitment phenomenon. This paper describes an Auto ABLB test software. This software automatically decides test frequency and intensity of first test tone. And it supports an automatic algorithm that analyses the subject`s reponses in the current step and then decides intensity of tone provided in next step. Also, this software supports an interface to control and monitor subject`s ABLB test. The assessment result is represented by a ladder diagram. The output of this software has been verified using a digital oscilloscope.
