Individual and group mean speech reception thresholds (SRTs). SRTs represent the signal to noise ratio required for a listener to repeat 50% of the sentences accurately. Lower scores indicate better ability to recognize sentences in noise. For subjects who benefited from MAP A, an additional control MAP (Odd/Even) was tested and results are shown in the fifth (open) bar. For each subject, the best MAP is indicated by a labeled arrow. In the group data, the asterisk indicates statistically significantly lower SRTs using MAP B compared to the SRTs using the subjects’ clinical MAP.
