Cognitive subdomain	Target speech	Masker	Hearing range	Pooled sample size	Pooled association (r)	95% CI of r	Z statistic and p value	I 2	95% CI of I2	No. of sign studies/No. of all studies
Working memory	Sentences	Unmodulated noise	All	349	.35	[0.25, 0.44]	6.64, <.001	0%	[0.0, 53.6]	5/8
Working memory	Sentences	Modulated noise		151	.32	[0.12, 0.49]	3.03, .002	36%	[0.0, 77.6]	2/4
Working memory	Sentences	>2-talker babble		317	.43	[0.28, 0.56]	5.21, <.001	50%	[0.0, 80.2]	5/6
Episodic memory	Sentences	Unmodulated noise		182	.31	[0.14, 0.47]	3.44, .001	15%	[0.0, 89.0]	3/4
