Continuous noise exposure can cause hearing effects, mainly noiseinduced hearing loss and tinnitus, and non-hearing. The annoyance (irritability and others) is one of the most important effects of noise on health. Purpose: To evaluate auditory and non-auditory noise effects among aerial grouping of military police. Method: The sample size was 50 Military Police. The auditory acuity was by pure tone audiometry. Auditory and non-auditory noise effects was conducted through a questionnaire adapted, based on Ferreira (2013). Statistical analysis was performed using the chi-square test to assess the association between the study variables and four outcomes (annoyance, stress, communication disorders and hearing loss). Adjusted logistic regression models were also used for each of the outcomes. Cronbach's Alpha Test was used to analyze the questionnaire reliability. Results: The majority of the Professionals considered the aircraft to be noisy (84%) and 88% classified it as intense. The main noise source inside the aircraft was the air traffic control radios. The military Police presented 40% hearing impairment mostly in the 3 kHz to 6 kHz frequency range. The mostly reported problems were the lack of attention and concentration, fatigue and tinnitus. Statistically significant association (p < 0,05) with stress, lack of attention, communication difficulties, irritability, annoyance and working performance were also found. The majority of the most discomforted professionals believed the lack of attention and communication difficulties (p<0,001), irritability (p=0,001) and working performance loss (p=0,001) was due to the environmental noise. Professionals that thought they can hear worse before (p<0,001) and felt they had hearing loss (p=0,009) had statistically significant association among hearing loss. Conclusion: Noise induced hearing loss occurred in 40% of the sample. The Annoyance, stress, communication difficulty and hearing loss were statistically associated with the workplace noise and various health effects. The internal consistency(Reliability)of the instrument was considered excellent
