Abstract

A Spatial Fixed-SNR (SFS) speech-in-speech intelligibility test is presented and the reliability and validity of the test is investigated. As part of the validation the SFS test was used to compare a linear hearing-aid setting to a setting with aggressive compression limiting. Two sub-groups of listeners were tested in a fixed-SNR paradigm at –5 and +5 dB SNR, respectively.
