ABSTRACT
INTRODUCTION: Tinnitus and associated handicap related to acoustic trauma sequelae have never been assessed in the French artillery. Although impulsive noise exposure to firearms and canons are thought to increase prevalence of tinnitus among soldiers, recent studies demonstrating this fact are missing. MATERIALS AND METHODS: Here, a representative sample of 389 soldiers from an operational mountain artillery regiment was surveyed. Soldiers personally concerned by tinnitus were invited to fill in a questionnaire. We assessed tinnitus and the associated handicap using a French translation of the Tinnitus Handicap Inventory (THI). Questions about attention/concentration problems, impaired speech hearing and understanding, sleep disorders, social and familial tension, irritability, depression, and tiredness as linked to tinnitus were the core of the questionnaire. RESULTS: Soldiers that completed the THI (n = 73, 19%) had a mean THI score of 18 ± 17, this mean score corresponded to a mild handicap. At this grade, tinnitus should be easily masked and should not interfere with daily activities. The percentage of soldiers concerned by tinnitus was slightly higher in the older age class, but there was no significant difference of THI scores between the different age classes. The most reported handicaps were attention/concentration problems, impaired speech hearing, and understanding. Among the THI fillers, eight soldiers (11%) had THI scores >36, indicating a moderate to severe handicap. CONCLUSION: Despite a mild tinnitus handicap, the percentage of people concerned by tinnitus in this regiment is higher (19%) than that in the estimated percentage of general population of European countries (about 10%). It should be of interest to replicate this type of study from other regiments and from other countries. Education and good fitting of hearing protection for prevention of acoustic trauma sequelae should still be encouraged.
