RESULTS Most compartments registered SPLs greater than 80 dBA noisiest compartment was engine-room, where vessel pilot works. tinnitus most commonly reported symptom (48.63%). higher prevalence observed engine-room keepers. Longer length time service, consequently, (in years), associated with auditory thresholds. CONCLUSION tolerance limits exceeded according legislation.
