چکیده

Background: Chronic occupational exposure to noise is an unavoidable reality in the countrychr('۳۹')s textile industry and even other countries. The aim of this study was to compare the sound pressure level in different parts of the textile industry in Yazd and in different parts of the textile industry. Methods: This cross-sectional study was performed on ۹۳۰ textile workers in Yazd. A questionnaire was used to obtain demographic information and how to use protective equipment. Then, to obtain the sound pressure level of each unit and device and to use the measurement principles, a calibrated sound level meter was used. Then the results were analyzed using SPSS Ver.۲۹ software. Results: The participants in this study were ۷۱۴ males and ۲۱۶ females with a mean age of ۳۵.۲۷ and ۳۳.۶۳ years, respectively. Seven hundred fifty-six participants (۸۱.۲۹%) were exposed to sound pressure levels higher than ۸۵ dB. Among the participants, only ۱۸.۳۹% of the people used a protective phone permanently. Except for factory E, with an average sound pressure level of ۷۷.۷۸ dB, the rest of the factories had an average sound pressure level higher than the occupational exposure limit. The sound measurement results of different devices show that the sound pressure levels above ۹۰ dB are related to the parts of Dolatab, Ring, Kinetting (knitting), Chanel, Autoconer, Dolakni, Open End, MultiLakni, Tabandegi, Texture, and Poy. Conclusion: Based on the results of the present study, noise above ۹۰ dB is considered as one of the main risk factors in most parts of the textile industry (spinning and weaving), which in the absence of engineering, managerial or individual controls on it causes hearing loss in becoming employees of this industry.
