Dyslexia is an unexpected impairment in reading and spelling despite a normal intellect.

Problems that are seen in dyslexia include reading, spelling, writing, speaking, or

listening problems. Nowadays, more children with learning and reading disabilities are

being referred to audiologists for hearing and auditory processing evaluations. These

children often have various difficulties, including problems with visual-spatial

organization, receptive and expressive language, phonology, attention, and in some cases,

auditory processing disorders. The role of hearing is critical in dyslexia and other

learning difficulties. Diagnosis of dyslexia is made based on the results of all the clinical

data attained. A number of audiologic tests demonstrate sensitivity to central auditory

nervous system disorders. These tests are used to demonstrate functional deficits in

patients with known lesions within the auditory system. It is likely that most children

with Auditory Processing Disorders (APDs) have comorbid conditions and therefore, the

audiologist needs to provide a diagnostic battery that will ultimately distinguish auditory

processing difficulties from other disorders. In this paper we will discuss about

audiologic tests that are used to evaluate auditory processing disorders in dyslexic


باز هم آلودگی صوتی تهران

آلودگي صوتي بعد از آلودگي هوا، مهم‌ترين آلودگي زيست محيطي و تهديد كننده سلامت انسان است، بر اساس اصول شنوايي‌شناسي، در محيط هاي با آلودگي بالاي ۸۰ دسي بل هر فرد مجاز است فقط ۸ ساعت يعني يك شيفت كاري فعاليت كند.

در صورتي كه ميزان آلودگي صوتي به ۸۵ دسي بل برسد بايد شيفت كاري نصف شود و به ۴ ساعت در شبانه‌روز كاهش يابد . البته فرد بايد حقوق ۸ ساعت را بگيرد ، اگر آلودگي صوتي به ۹۰ دسي بل برسد، كار كردن بيش از ۲ ساعت خطرناك است و اگر اين آلودگي به ۹۵ دسي بل برسد فرد حداكثر بايد يك ساعت در محيط كار كار كند و معادل ۸ ساعت حقوق بگيرد. ادامه مطلب
