Abstract
Introduction: We estimated the noise in an industrial shoe factory to determine the effect of noise in the workplace on the hearing status of the workers in such environments. Materials and method: the intensity of noise in dB in different parts of the factory was estimated. Then working people in each part was selected randomly and their hearing thresholds were evaluated by Conventional audiometry. Results: The results demonstrated that 23% were required to estimate thresholds more precisely and 95 needed close examination by Otolaryngologist. Besides, 10% of the workers suffered sensory neural hearing loss whose 2% of them diagnosed as NIHL. Discussion: Since the mentioned factory has good hearing conservation program for the workers, it seems that promoting the program can decline the number of noise induced hearing losses to the least numbers.

Abstract
Background and Aim: Speech is the essential need of the social life. To acquire that, children highly rely on the normal senses and speech full environment. The normal auditory senseis the most important need. Early amplification intervention in children with hearing difficulties is advised. Cochlear implant technology provides an effective help for hearing-impaired children in recent decades. With regards to new and limited implantation services in Iran, the effects of operation age on speech and language of implanted children was not studied yet. The purpose of this study was to compare articulation errors in cochlear implanted children with different operation age. Materials and methods: In this cross-sectional study, ten cochlear implanted children before three and eleven after four years old were evaluated. The participants were without any anatomical, visual, and intelligence abnormality and 2.5-3 years was passed from their operation. Then, by using Picture Pho-netic Test (PPT), the articulation errors of individuals were extracted and for more evaluation of the er-rors and complete of PPT, we, also used their excited connected speech by presenting pictures. By application of t-test and using SPSS software, the data was analyzed. Results: Data analysis indicated that, there was meaningful significant difference between substitute errors and whole errors in two gropes but there was not meaningful significant difference between de-stroyed errors in two gropes. Conclusion: The children who undergoing operation after 4 years old had severed articulation disorder than other grope. These issues indicated that the earlier operation of children will lead to improve the speech skills and reduced the articulation errors.
