Abstract：Objective To study the protective effect of cotton ball against hearing damage during rifle shooting and lack of personal hearing protective devices. Methods Fifty-three adults were divided into a cotton ball protection group (n=40) and a no protection group (n=13). Self-assessment hearing questionnaires were completed after rifle shoot-ing. Results Three in the cotton ball group (7.5%) and 7 in the no protection (53.8%) reported ear problems after shoot-ing. Tinnitus was reported by all the persons with ear problems after shooting and lasted for 12 to 24 hours. Conclu-sions Tinnitus is a common compliant in rifle shot exposure-induced ear damages. When there is lack of standard hear-ing protective devices, cotton ball can be used to reduce noise-induced ear problems effectively.
