ABSTRACT
Teachers are at a higher risk for occupation-related voice disorders than the general population. The aim of this work is the investigations on the relationships between vocal doses and clinical status, acoustical conditions (noise and reverberation) in the classrooms and subjective evaluations of vocal effort and fatigue. At clinical evaluation 41% of the teachers showed no sign of vocal disease. Students talking in the classroom is the most annoying, noise source in classrooms. The consequence of the poor acoustics in all the schools was the decrease in students question perception. The main cause of a vocal pathology was time dose.
