Abstract
Background: Pathological and physiological disabilities of human auditory receptors reduce speech intelligibility under hearing loss (HL) at high frequencies. Objectives: The objective of the study is to investigate the speech-intelligibility-enhancement (SIE) in elderly with high-frequency HL (HFHL) through visual-speech-perception (VSP). The hypothesis is that the VSP of spondee words (two-syllable words with equal stress on both syllables) is properly recognized and reproduced with HFHL. Also; to decide the statistical relevance of the precise significant difference in speech discrimination (SD) with VSP on the subjected ear. Methods: Observational and descriptive studies of SIE with VSP on 12 elderly listeners (24 clear ears; without wax impaction) with progressive and bilateral HFHL were examined. The entire experimental records were checked for distribution with normal (Gaussian) using the Shapiro–Wilk's and paired Student's t-test (parametric test) had the 5% (0.05) significance level (α). Results: We analyzed, improved, and better performance in SIE with HFHL through VSP. The statistical P (probability) measure was calculated nothing, i.e., 0 (P
