Comparison of Some Speech Intelligibility Tests in the Evaluation of Hearing Aid Performance

Abstract

A sentence intelligibility test and three monosyllabic word intelligibility tests, recorded through three hearing aids, were presented to 36 subjects with diverse types of hearing loss. Although hearing aids were rank ordered meaningfully on the sentence intelligibility test-in inverse proportion to the harmonic distortion-performance differences were not systematically reflected in the monosyllabic word test results.
