Since their academic formation, the dentists surgeons are concerned with the high productivity in clinic and with the final result of the work, neglecting the way as it is executed, which reduce their work capacity and exhibits them to occupational diseases that could be minimized and/or forewarned. This research had as the main objective to investigate the knowledge of the Dentistry academics of Rio Grande do Norte Federal University concerning the Noise-induced Hearing Loss (NIHL), relating them at the noise levels that they are exposed, as well as to the preventive measures taken during the clinical activities. Was observed that 95% of the individuals know that the dentist surgeon is a professional in risk for NIHL. Among the causes of NIHL, the one that obtained the largest frequency citation was the high-speed handpieces, reminded by 92,4% of the academics. Among the students which enumerated protective measures for NIHL, 92% mentioned the use of the ear plugs, although 97% of the researched have told do not use any kind of preventive measure related to the noise. Was also observed that 96% of the academics notice the noise during the clinical attendance, what inconvenience 28,1% of them. Related the noise levels, the high-speed handpieces of the academics presented a medium value of 80,5 dB varying from 72,3 to 88,3 dB. The average of the ambient noise observed at the Integrated Clinic was about 74,8 dB. In spite of the noise levels in this research were observed below the established limits of tolerance by the legislation, they can provoke damages to the Dentistry professionals' health, or that suggests the need of an intervention and use of immediate preventive measures able to generate a healthy atmosphere of work and less risky / A racionaliza??o do trabalho na Odontologia tem levado o profissional a trabalhar por meios e sistemas fundamentados na ergonomia, tornando seu trabalho eficiente e menos cansativo. Desde sua forma??o acad?mica, os cirurgi?es dentistas s?o preocupados com a alta produtividade em cl?nica e com o resultado final do trabalho, negligenciando a maneira como este ? executado, o que leva a redu??o de sua capacidade de trabalho e exposi??o a doen?as ocupacionais que poderiam ser minimizadas e/ou prevenidas. Este trabalho teve como objetivo principal investigar o conhecimento de acad?micos de Odontologia de uma Universidade P?blica do Rio Grande do Norte acerca da Perda Auditiva Induzida pelo Ru?do (PAIR), relacionando-o aos n?veis de ru?do a que est?o expostos e ? tomada de medidas preventivas durante as atividades cl?nicas. Foi observado que 95% dos indiv?duos sabem que o cirurgi?o dentista ? um profissional de risco para a PAIR. Dentre as causas da PAIR, a caneta de alta rota??o foi lembrada por 92,4% dos acad?micos. Dos que enumeraram medidas de prote??o para a PAIR, 92% citaram o uso do protetor auricular, embora 97% dos pesquisados tenham relatado n?o usar nenhum tipo de medida preventiva em rela??o ao ru?do. Observou-se tamb?m que 96% dos acad?micos percebem o ru?do durante o atendimento cl?nico, o que chega a incomodar 28,1% deles. Quanto aos n?veis de ru?do, as canetas de alta rota??o dos acad?micos apresentaram um valor m?dio de 80,5 dB variando de 72,3 a 88,3 dB. J? a m?dia do ru?do ambiente observada na Cl?nica Integrada foi de 74,8 dB. Apesar dos n?veis de ru?do observados neste estudo encontrarem-se abaixo dos limites de toler?ncia estabelecidos pela legisla??o, podem provocar preju?zos ? sa?de dos profissionais da Odontologia, o que sugere interven??o e uso de medidas preventivas imediatas capazes de gerar um ambiente ocupacional saud?vel e com menos riscos
