Coefficients of correlations (Pearson’s r) between cognitive tests and speech intelligibility.

	SNR at 84% speech intelligibility	Actual speech intelligibility at estimated 90% level in SSSW noise	Actual speech intelligibility at estimated 90% level in ISTS noise
Reading span	0.14	−0.13	0.14
Letter memory test	0.07	0.01	0.29
Simon task	−0.11	−0.19	−0.57**
TRT	−0.38	−0.27	−0.46*
Delayed recall of reading span test	−0.11	−0.36	−0.09

* Correlation is significant at the 0.05 level (2-tailed)

** Correlation is significant at the 0.01 level (2-tailed)
