Abstract

Background: The ability to understand speech in background noise is a crucial skill for proper communication and learning. Understanding speech through noise is a skill that develops well into an individual’s adolescent years and becomes adult-like at around the age of 15. Listening in noise in younger children is of particular concern at school because early educational skills may be taught in noisy settings. Some children also appear to be at a double challenge when listening under adverse conditions (noise, reverberation and background bubble). Spatial listening is the capacity of the auditory system to interpret or exploit different spatial paths by which sounds may reach the head. It is used to isolate speech stream from simultaneous noise.
Aim of the work: To develop an Arabic test to evaluate spatial processing in children and to standardize the developed test on normal Arabic speaking children.
Methods: Sixty normal hearing children classified into three subgroups: Subgroup I: (6 to< 8 years), Subgroup II: (8 to< 10 years) Subgroup III: (10 to 12 years). They were tested in a sound treated room using newly developed spatial listening material. The total number of the sentences were 128 sentences which were divided into 16 lists. The first 8 lists were recorded by female voice and the other 8 lists were recorded by male voice. They were mixed using audacity software with story noise. Four test conditions were examined according to location of target sentences in relation to noise and type of voice. Scoring was done by measuring the SNR 50% which is the level at which the child repeated 50% of the number of words per list.
Results: The performance data of the entire study group and the study subgroups according to age were calculated. The 95% confidence limits were calculated to determine the cut off points for abnormal scores as a function of age for each of the three subgroups separately. The scores that fell below the lower 95% confidence limit were considered abnormal.
Conclusion: Spatial listening test was developed and standardized for assessment of spatial listening in Arabic speaking children with age ranging from 6-12 years.
