Abstract: Objective To investigate the validity of the simplified version of mandarin hearing in noise test (MHINT) comparing with the original version,and observe the speech perception abilities for mandarin in children with high functional autism spectrum disorders (ASD) comparing with normal children.Methods Eighteen children diagnosed as high functional ASDs and their normal peers were tested by original and simplified version of MHINT.The agreement of two versions MHINT and the speech perception abilities were compared between groups.Results The agreement of simplified and original MHINT was acceptable under both conditions.ASD group (quiet condition:r=0.931,P=0.001;noise:r=0.869,P=0.018),control group (quiet condition:r=0.911,P=0.001;noise:r=0.858,P=0.003).No statistical differences between two groups in both tests under quiet conditions were found.Under noise condition,the test scores were significantly lower in ASD group in both tests.Conclusions The validity of simplified version MHINT is acceptable and could be used in later studies.High functional ASD children could have difficulties in speech perception in noisy background and their ability of sound complex identification could be impaired.
