A concise Description of Non-linguistic features (Such as Familial, educational and Health information) and linguistic skills in hard of hearing children will be helpful in compensating for their disabilities. In the current study we studied 75 school-Children with average hearing Thresholds of 55-70dB in better ear. All the subjects aged between 8-16years-old with the average age of 11.04.We studied 27 non-linguistic variables by using questionnaire and 32 grammatical variables by studying evoked speech in the participants. The average utterance length of the subjects was estimated 2.763 words. 29% of the all participants' utterances was accurate and just 16.3% of the verbs were produced accurately.One of the most common errors in sentence and verb level, was the mistaken ably omitting of the structural features, the tense problem of the verb and also the mismatching between subject and verb. We also observed a significant correlation between some non-linguistic features such as grade, previous education in conventional schools and the rate of hearing aid usage and the number of accurate utterances in participants.

Background and Aim: Turner syndrome is the most common sex chromosome abnormality in females, affecting an estimated 3% of all conceiving females. Otologic disease is a common problem in Turner syndrome patients that is due to a combination of small dysfunction Eustachian tube, palatal dysfunction and cochlear malformation.
Methods: This study assessed the otologic and audiologic characteristics of a group of Turner syndrome patients. We studied 40 Turner patients aged 10 to 20 years (mean age: 15.84 years, SD=2.67). Pure tone audiometry was carried out for all of them.
Results: Forty percent of the patients reported a history of middle ear disease. Analysis of audiometric data in 40 patients tested reveals normal hearing in 47.5%, pure sensorineural hearing loss in 32.5%, pure conductive hearing loss in 17.5% and mixed hearing loss in 2.5% of patients.
Conclusion: Careful follow up during early childhood of children with Turner syndrome is necessary to detect middle ear disease and prevent the probable sequel. However, long term periodic follow up is mandatory even after resolution of middle ear disease to detect sensorineural hearing loss.

Background and Aim: In the process of assessing the nasalance scores in patient’s speech, it is vital to know about normative data in the speech of normal subjects. The main objective in this study was to obtain normative data on nasalance scores in normal Persian-speaking children aged 3.5 to 6.5 years.

Methods: In this cross-sectional and comparative study, nasalance was measured in the speech of 112 children (55 boys and 57 girls) in Tehran, Iran. After auditory screening and speech assessments, the subjects who get the sufficient criterions entered the study. Speech sample was obtained by imitation and repeating sentences (14 oral and 3 nasal sentences) and mean nasalance score was measured by Nasal view software.

Results: A mean nasalance score of 46.25% was obtained for nasal sentences and a mean score of 43.67% for fricative sentences, 43.41% for affricative sentences and 42.21% for stop sentences. There was higher nasalance scores in girls but the difference was not significant (p=0.201) there was a significant difference in nasalance scores between different age groups in stop (p=0.037), fricative (p=0.036) and nasal sentences (p=0.032).

Conclusion: Findings of this study prepared good statistical data about nasalance scores in normal Persian-speaking children aged 3.5-6.5 years. The study also revealed that nasalance scores can be different in sentences with same manner of articulation and can be affected by presence or absence of nasal consonants and even age.
