Performance of deaf children using ear-level and body-worn hearing aids

Area of Science:

• Audiology
• Pediatric audiology
• Hearing aid technology

Background:

• Profoundly deaf children require effective amplification.
• Hearing aid technology varies, with ear-level and body-worn devices being common options.
• Comparative effectiveness of different hearing aid types in children is crucial for audiological management.

Purpose of the Study:

• To compare the audiological benefits of ear-level versus body-worn hearing aids in profoundly deaf children.
• To assess the impact of hearing aid type on speech discrimination and auditory comprehension.
• To evaluate the effectiveness of different hearing aid styles in a pediatric population.

Main Methods:

• A cohort of 37 profoundly deaf children (aged 6.5-8 years) underwent audiological evaluations.
• Participants were assessed using the Word Intelligibility by Picture Identification (WIPI) test and a Question Comprehension Task.
• Children were categorized based on their hearing aid type: ear-level (N=15) or body-worn (N=22).
• Unaided audiograms were compared between the two groups.

Main Results:

• No significant difference was found in mean unaided audiograms between children using ear-level and body-worn aids.
• Ear-level hearing aids demonstrated significantly greater improvements in tested hearing compared to body-worn aids.
• Children using ear-level aids achieved significantly higher scores on the WIPI (both visual and auditory-visual conditions) and the Question Comprehension Task.

Conclusions:

• Ear-level hearing aids are more effective than body-worn aids for profoundly deaf children in terms of audiological outcomes.
• The type of hearing aid significantly impacts speech discrimination and auditory comprehension abilities in this population.
• Findings support the use of ear-level hearing aids for enhanced auditory rehabilitation in children with profound hearing loss.
