Abstract

The purposes of this study were to develop and provide the normative data of Arabic screening tool for screening the children with auditory processing disorders: an Arabic version of Adaptive Auditory Speech Test (AAST) in quiet for screening the peripheral hearing in dB SPL units; an Arabic AAST in binaural noise for screening the temporal interaction deficit: listening speech in binaural noise in dB SNR units, then teetaatoo test with a five subtests for screening the Modern Standard Arabic language phonemes identification ability. Participants included 338 children aged from 5 to 7 years old (138 males, 200 females; mean age = 6.08 years with standard deviation = 0.8) from a regular nursery school which called Baroot Summer Club in Beni-Suef in Egypt were recruited to participate in the study. According to the calculated Norms of AAST in quiet and through a meeting with the teachers of children in the nursery school, 129 children were sift out with no hearing loss, negative histories of neurological disorders, head trauma or surgery, dizziness, and attention deficit disorder/attention deficit hyperactivity disorder. 129 children were screened for listening in binaural noise using the Arabic AAST in binaural noise, then the left 94 children, because 35 children couldn`t complete the testing, was screened for phonemes identification ability using teetaatoo test(the five sub tests). For the AAST in quiet, 21 to 33 dB SPL is the normal range of the hearing peripheral loss, especially, for the AAST in binaural noise, there are three different norms; -9 to -13 dB SNR is the normal range of children aged 5 years old, -10 to -13 dB SNR is the normal range of children aged 6 years old, and -10 to -14 dB SNR is the normal range of children aged 7 years old. Finally, for the five subtests (teetaatoo): > 85% (correct answers) is the normal percentage of the Cons-A, >62& (correct answers) is the normal percentage of the Cons-B1, >76% is the normal percentage of the Cons-B2, >63% (correct answers) is the normal percentage of the Cons-B3, and 84% (correct answers) is the normal percentage of the Vow-A. Further, according to the previous norms, 23 children represent 17,8% from the whole sample (N=129) with a normal speech recognition threshold have scored abnormally on the speech listening in bin-noise (AAST in bin-noise) or on at least one subtest from teetaatoo subtests and were considered at risk for learning disability because of their scores on a SIFTER.
