A test-retest reliability study on clinical measurement of masking level differences.

Measurement of binaural release from masking was studied in 30 normal and 10 hearing-impaired subjects to determine the test-retest reliability of masking level differences measured with a clinically feasible technique on generally available clinical equipment. The instrumentation/methodology was found to elicit reliable, consistent, rapid measurements for both 500-Hz and speech (spondaic) stimuli which were comparable with those generally reported in the literature as laboratory-conducted experiments.
