Spatial release from masking is measured by adapting target-to-masker ratio to threshold

Evidence

The HI listeners had a moderate, bilaterally symmetric, sloping sensorineural hearing loss with a 4FAHL of 48 ±5dB. Subjects were assessed with a Matlab version of the LiSN-S test (Glyde et al. 2013 ), in which short, meaningful sentences (e.g., “The brother carried her bag”) were presented in an ongoing two-talker background. Target and distractors were spoken by the same female talker and target sentences were preceded by a brief tone burst. Using HRTFs, target sentences were presented from 0° azimuth and the distractors from either 0° azimuth (colocated condition) or ±90° azimuth (spatially separated condition). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1740
