2.5 Statistical analysis
A paired t-test was used to perform within-subject analysis between
unaided and aided conditions, and an independent t-test was used to
compare the NH and SSD groups. Repeated-measures analysis of variance
(ANOVA) was performed to identify significant differences in SNR across
Co-located and Separated conditions. Linear regression was used to
reveal the relationship between SRTs in the Separated condition and age.
Statistical significance was represented as p <0.05. SPSS 26.0
and GraphPad Prism 8.0 were used to analyse data and draw diagrams.
