Background and purpose: Proper resonance is a major factor for the comprehension of speech in individuals with hearing loss. These people have low speech intelligibility caused by inappropriate resonance. Therefore, nasalance measurement is a principal aspect of the assessment of people with hearing loss. This study aimed at determining nasalance in children with hearing loss.
Materials and methods: This cross-sectional study was conducted in 63 children with moderate, severe, and profound hearing loss. The participants included 51 girls and 12 boys aging 8-13 years old. They were randomly selected from Tehran, Iran. The degree of hearing impairments was determined. Speech samples were obtained using Sentence Reading Test (14 sentences with oral consonants and 3 sentences with nasal consonants) and the nasalance was measured by Nasal View software. Then, data analysis was performed.
Results: The mean nasalance in nasal sentences were found to be significantly higher than those of oral sentences between the groups studied. The mean values for nasalance in nasal sentences read by children with profound hearing loss were significantly higher than those read by children with severe and moderate hearing loss.
Conclusion: In this study, the mean nasalance in children with moderate hearing loss was the lowest in reading sentences with oral consonants and nasal consonants. Also, it was found that hearing loss influenced the nasalance.
