Table 3 . Difference between word discrimination scores (WDSs) for each pair of three signal to noise ratios (SNRs) (n=50) .

Pair SNR (dB)	Mean (%)	SD	P Value
0 and +5	64.7	4.66	0.040
0 and +10	70.8	6.76	0.025
+5 and +10	78.3	6.85	0.095

WDS: Word discrimination score (WDS), SNR: signal to noise ratio
