Introduction. Patients with impaired higher hearing function, including those with Language-based Learning Disability (LLD), find it difficult to perform normally in the noise-polluted environment. LLD children may experience difficulties with absorbing verbally transmitted information in noisy classrooms, whereby their learning progress may be considerably hindered.
Aim. Assess the ability to understand speech in noise by LLD children.
Material and methods. The subjects were 75 LLD students at the age of 8 to 16years. Speech audiometry in silence and in noise was used, with a + 12dB signal to noise (S/N) ratio. The results were compared with those for healthy students without learning problems.
Results. Central auditory processing disorders (CAPDs) were diagnosed in 73 children and auditory neuropathy was detected in 2 children. Elevated speech perception threshold in noise was recorded in 42 of the patients, while wider articulation curves in the speech in noise were noted in 66 of the patients. No such changes were observed in healthy students.
Conclusions. Widening of speech audiometry curve in noise in a Language-based Learning Disability students vs. that obtained in silence may point to central auditory processing disorders.
