Effect of UCL on aided Articulation Index calculation.
Nine hearing threshold patterns and uncomfortable loudness level combinations were used in comparing three hearing aid prescriptive procedures by means of a modified Articulation Index. In a minority of the comparisons a small dynamic range required a reduction from the gain that would have been prescribed. For these cases reducing the real-ear gain, in turn, resulted in a mean lowering of the Articulation Index by 0.03 for POGO and 0.08 for the Berger Method.
