A versatile computerized audiometry station has been developed in order to investigate psychoacoustical phenomena and their possible correlation with the form of the external ear canal. Auditory thresholds with eventual additional masking, discomfort level, magnitude loudness estimation, and psychoacoustical tuning curves are measured. Furthermore, ear canal;s transfer function and hearing aid's gain measurement are also provided. This station is interfaced to a personal computer (IBM-compatible). The obtained results are graphically displayed, printed if needed, and stored on disk allowing for statistical analysis of the accumulated data.
