Avaliação do desempenho acústico de sala de aula em uma escola pública do Distrito Federal

Abstract

The study about acoustic comfort in a classroom is considered important because it is necessary to verify the environment acoustic quality in the success of an individual's learning process. The main objective of the present study was to evaluate the acoustic performance of a classroom at a public school in Distrito Federal, to identify the acoustic factors that can cause damage for the learning process. The data was collected at several preselected spots in the school area and submitted to analysis of noise and times of reverberation in these places. The results show that most parameters did not met the expected levels according to the NBR standards. Suggestions were made, in order to improve the acoustic comfort and the learning process. It was concluded from the results obtained that the lack of acoustic comfort in classrooms evidences the need for improvements. The construction market has acoustic insulation materials capable of conferring to the classrooms the appropriate insulation and acoustic treatment, but unfortunately this does not happen effectively.
