Note. All analyses were conducted with the data from all six prototype listening situations combined, with the exception that the PLS4 data were not included in the CST data analysis. Bold emphasis indicates statistical significance. HA = hearing aid; PSAP = personal sound amplification product; PLS = prototype listening situation.
