Speech reception thresholds are measured adaptively with listener self-scoring.

Evidence

Except for experiment 1 (HP target), each experiment was composed of two sub-experiments of eight conditions because no asymptote was reached with the first set of eight conditions. Experiment 1 tested only eight conditions. In each sub-experiment, each SRT was measured using a list of twelve target sentences and an adaptive method (Brand and Kollmeier 2002 ). The twelve sentences were presented one after another against a different noise excerpt corresponding to the same condition. Listeners were instructed to type the words they heard on a computer keyboard after each presentation. The correct transcript was then displayed on a monitor with the key words highlighted in capital letters. Listeners identified and self-reported their score (number of correct key words they perceived). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3549
