SUMMARY:

Urban bus drivers are exposed to noise during the work. When at high levels, occupational exposure to noise may be associated with hearing tinnitus, communication difficulties and hearing loss. The aim of the present study was to measure the levels of exposure to which urban bus drivers in the Federal District are subjected during their working hours, as well as to investigate the prevalence of noise induced hearing loss (NIHL).The sample consisted of 500 public transport drivers with a mean age of 46 years and working time predominantly over 15 years. Anamnesis was applied with questions about life and work habits, sound pressure levels were measured using a CESVA model SC101 sound level meter, and data from the last sequential audiometry performed by the workers was collected. Difficulty communicating inside vehicles was reported by 20.40% of professional drivers and hearing buzzing noises at the end of working hours by 28.40%. There were 39.80% of drivers with tests suggestive of NIHL, with 60.80% of bilateral cases and 39.20% unilateral. 72.86% of the compromised audiometries belonged to individuals with more than 15 years of experience in the profession and there was a progression in the number of exams with NIHL suggestion the greater the age of the driver. The sound pressure levels were not higher than the exposure limit and the level of action provided for in Occupational Hygiene Standard 01.
