The auditory system helps control voice production, and the present case study illustrates this relationship and reveals how severe to profound post-lingual Hearing Loss (HL) impacts voice quality and dynamics and how uni- and bi-lateral cochlear implantation (CI) improves performance in spontaneous speech....
No actionable change for most clinical audiologists; this single-subject longitudinal case study illustrates voice quality changes linked to severe-profound hearing loss but lacks the sample size to guide practice changes — findings may inform SLP/audiology collaborative management.
The case highlights the often-overlooked impact of severe hearing loss on voice production control, pointing toward a need for cross-disciplinary monitoring of voice quality in adults with post-lingual hearing loss.
- 01Longitudinal single-subject study tracking voice quality changes in a severe-to-profound hearing loss adult.
- 02Both acoustic measurements and trained listener (auditory-perceptual) evaluations were used.
- 03Illustrates the auditory feedback loop's role in maintaining normal voice production.
- 04Findings are limited by N=1 design but offer a detailed longitudinal view.
