TABLE I.
Correlation coefficients and P values (parentheses) for each of the test conditions. PTA, pure tone average; WRS, word recognition scores; LNR, amplified speech recognition scores; QuickSIN, quick speech in noise test; SMD, spectral modulation detection; SRD, spectral ripple-phase discrimination; ERB, equivalent rectangular bandwidth from auditory filter measures.
