Table 2.

Correlation analysis between pure-tone averages of high-frequency hearing loss and speech recognition scores with different compression and different test backgrounds.

	Compression ratio of speech in quiet			Compression ratio of speech in noise
	1	0.8	0.6	1	0.8	0.6
Pearson correlation	−0.279	−0.269	−0.329	−0.694	−0.627	−0.536
p value	0.015∗	0.019∗	0.004∗	<0.001∗	<0.001∗	<0.001∗

For NH groups, the average was calculated across 2, 4, and 8 kHz; for HF SNHL groups, the average was calculated across frequencies where exhibited hearing loss. ∗ indicates p values smaller than 0.05.
