Test-Retest Consistency of Clinical Hearing Aid Tests

Abstract
Aided discrimination scores and speech reception thresholds were determined on 40 subjects, twice on the same day. A second group of 37 subjects yielded similar repeat data from tests performed 2 weeks to 3 months after the first test. Speech discrimination scores had a high degree of test-retest consistency, not only with one audiologist, but with those obtained with other audiologists. Coefficients of correlation for discrimination tests ranged from .83 to .92. Aided speech reception thresholds were less consistent with correlations ranging from .48 to .68.
