چکیده

results the mean age and work experience of workers were 31.39 ± 5.6 and 4.35 ± 2.5 years, respectively. among the exposed-to-noise personnel, 7.35% used hpds constantly; 75% used hpds for only short periods of time (less than four hours) and 17.65% did not make use of them at all. regarding the sound intensity and the level of noise reduction of hpds, among the 112 workers who used such devices, 59.6% had hpds with appropriate protection and 22.8% used inappropriate ones. there was a significant relationship between age, work experience, education and use of hpds. inappropriateness and difficulty in the use of the devices were also reported as the main reasons for not using them. conclusions this study showed an unsatisfactory situation in the mentioned industries for hpds usage; low percentage of usage, low preparation rate, the inappropriateness of some of the hpds, and unawareness of some of the workers. a noise training and education program is recommended to be developed for workers in order to protect them from hazardous noises. background exposure to noise can result in hearing loss in many industrial workers. in many cases, hearing protective devices (hpds) are considered as the main protective objects. as a large number of workers in the iranian carpet weaving industry are usually exposed to noise levels exceeding the permissible exposure limits. objectives this study was conducted to evaluate the use of hpds, quality of available equipment and possible reasons for lack of protective devices usage. methods in a descriptive, cross-sectional study, 136 workers of kashan carpet industries exposed to noise pressure levels greater than the action level defined in the iranian legislation (85 db (a) 8 h/d) were evaluated for hpds use. the quality and hpds suitability was defined according to the workers exposure to noise, available hpds and their noise reduction rate (nrr). the reasons for non-usage of hpds were evaluated as well. data were analyzed using the spss v. 18 software.
