title: [Polymeric hearing protectors in sport shooting].
abstract: Using hearing protectors during exposition to noise is fundamental to hearing loss prevention. The optimal choice of hearing protectors should take into consideration not only the physical characteristics of the acoustic environment which imply the traumatic action of noise, but also some individual preferences of the user. All contemporary produced hearing protectors both earmuffs as well as earplugs are made of synthetic polymers e.g. ABS, polyvinylchloride, polyethylene, polyurethathane, silicone rubbers. The type of the material used determines hardness, incompressibility and plasticity of the hear protector and may cause some discomfort. A special group of individuals exposed to noise are sport shooters in which (whose) case the exposition to impact noise is several times higher above standards. The aim of this work was an appraisal of the individual preferences in the choice of hearing protectors. The properties of polymers used for the production of hearing protectors were also taken into consideration. 104 females and 93 males representing master class were interviewed in this study. The analysis of the answers indicated that abandoning of hearing protectors by some shooters is due to the frequent skin irritations, overheating in the ear canal and allergy. Shooters linked these problems with the materials used for the production of hearing protectors. Earplugs were preferred by females, whereas males indicated earmuffs as their preferred choice. Females preferred earplugs made of soft materials which can be easily fitted to ear canal. Those males who used earplugs preferred protectors made of hard plastics as they thought this make better insulation. It can be concluded that the choice of the hearing protectors should not be done on the basis acoustic signal characteristics only, but also should reduce some discomforts resulting from properties of the materials used for their production.
