The acoustic environment of learning-teaching activities at a dental college is characterized by high noise levels in relation to other teaching areas, due to the exaggerated noise produced by the use of dental equipments by many users at the same time. Noise can have both auditory and non-auditory effects. It is well known that increased noise levels produce non-auditory effects like stress reactions with variations in heart rate, blood pressure, respiration, blood glucose and lipid levels, associated with psychical consequences like annoyance, mental fatigue and a reduction in efficiency, as well as auditory effects like noise-induced hearing loss (NIHL).
