Sensory processing is an important factor in development and affects their function in daily living activities. Hearing impairment may lead to some difficulties in sensory processing in children with hearing impairment.
Objectives:  In this cross sectional study, we compared sensory processing of children with hearing impairment and their normal hearing peers who were between 3 to 6 years old.
Methods: The study, the population consisted of 60 normal-hearing and hearing-impaired children with hearing aids in Shiraz who was between 3 to 6 years old. Dunn’s Short sensory processing test was utilized in two groups. The results were statistically analyzed by SPSS 21 at a significant level under 0.05.
Results: Independent t-test results showed that there was no significant difference between the two groups in the processing of total sensory processing (P-value = 0.097), Touch sensitivity (P-value = 0.043), olfactory and taste sensitivity (P-value = 0.259), movement sensitivity (P-value = 0.079), sensory seeking (P-value = 0.229), hearing processing (P value = 0.390), low energy and weakness (P value = 0.916), hearing and vision sensitivity (P-value = 0.429). The total score mean was 15.28±4.8 for children with hearing aid and 15.28±4.6 for normal hearing children.
Conclusions:  The results of this study show that hearing impairment’s impact on sensory processing is inconceivable and needs more research to be addressed. Although it seems that hearing impairment may affect one area of sensory processing.
