TABLE 2.

Correlations (r) between dependent variables at T2.

	RS	NR	SP 4,000 Hz	SP 3,000 Hz	SP 2,000 Hz	PD	PD_n
Digit span (DS)	0.50^∗∗	0.40^∗∗	0.17	0.23	0.11	0.41^∗∗	0.22
Recall of sentences (RS)		0.51^∗∗	0.33	0.38^∗∗	0.24	0.40	0.40
Non-word recall (NR)			0.39^∗∗	0.53^∗∗	0.48^∗∗	0.60^∗∗	0.43^∗∗
Speech perception (SP) at 4,000 Hz				0.64^∗∗	0.41^∗∗	0.41^∗∗	0.51^∗∗
Speech perception (SP) at 3,000 Hz					0.72^∗∗	0.46^∗∗	0.62^∗∗
Speech Perception (SP) at 2,000 Hz						0.45^∗∗	0.37
Phoneme discrimination (PD)							0.55^∗∗

PD_n = Phoneme Discrimination with background noise. Due to the risk of a type I error for calculating numerous correlations, p-value for all correlations was adjusted to p < 0.002 (see Cupples et al., 1984). ^∗∗The correlation is significant at the level of 0.002.
