Evaluating the directional effects of acoustic horn style hearing aids using the QuickSIN procedure

This paper evaluates the directional effects of two hearing devices – an antique London Dome horn style device and a constructed Cupped Hand. The comparisons were made using the Quick SIN (Speech in Noise) adaptive test which measures signal-to-noise ratio loss.
