Introduction: Professionals of the dental area handle daily with noisy instruments, what may come to cause audibly alterations and negative effects at the communication and life quality of these professionals. Considering the fact that such noise can not be eliminated, it is important that the awareness of future dental professionals is initiated early on in the university, mentioning the risks to which they are being exposed so that they can control them with prevention and treatment, as well as acquire consistent information about the behavior of the auditory thresholds of surgeon dentists. Objective: To investigate the knowledge about hearing health of students of graduation in odontology, characterize the audiological profile and listening habits of the research participants. Methodology: After approval by the Ethics Committee under case number 045/2009, the project was conducted in two stages. The first consisted of questionnaires to 367 students of undergraduate courses in Odontology from the Faculty of Odontology of Bauru FOB/USP and USC and from Faculty of Odontology of São Paulo FO/USP. In the second stage, 25 students from first and fourth years of undergraduate faculties of Bauru were invited to conduct the following assessments: audiometry, speech audiometry, impedance tests and additional assessment (high frequency audiometry and otoacoustic emissions and distortion product). Results: In the first stage, it was observed that students are unaware of the risk the workplace and the leisure environment provide the hearing health and, thereby, it was verified that awareness is needed about noise exposure and its consequences, in order to create a program of promotion and prevention, especially in occupational health in this population, considering that this problem affects the quality of life of those who work in the dental profession. In the second phase 25 participants completed the tests (X = 23 years). Although the thresholds meet according to normality by the WHO (World Health Organization) and also to Ordinance No. 19 of Ministry of Labor, there was a notch in the frequency of 6 kHz and 12,5 kHz in both ears in conventional audiometry and high frequency audiometry. The average minimum found in the right ear was 4.6 dB at 14 kHz to the left ear was 4 dB at 1 kHz and the average maximum for the right ear was 12.4 dB at 6 kHz and to the left ear was 14 dB at 6 kHz. For speech audiometry and immittance, 100% of the participants presented examination consistent with conventional audiometry. In the record of EOE, it was found that the higher the threshold of audibility frequencies studied, the more evident is the lack of EOE-t and EOE-DP for both ears, except when comparing the hearing threshold at 1 kHz in the EOE-t, probably due to contamination by background noise during the registration thereof and in the frequency of 3 kHz in the EOE-DP. Conclusion: The questionnaires applied proved to be efficient, reaching the objective. As for the characterization of the audiological profile, it was concluded that, the test of both transient otoacoustic emissions and distortion product, proved more efficient as a complementary test for early detection of hearing alterations in this population.
