Sound pressure levels in classrooms of a University and its effects on students and professors

Measure the sound pressure levels in classrooms of a university as well to verify the self-perception of noise in the educational environment and its influence on the activities carried out by students and professors.

The study was carried out with students and professors who answered a questionnaire regarding self-perception of noise in the classroom, as well as the presence of auditory and non-auditory complaints. Measurement of sound pressure levels was performed in ten classrooms of Pontifical Catholic University of Minas Gerais. The points for measuring the sound pressure level inside the classrooms were selected according to the literature and legislation: three distinct points, totaling nine measurements in each room.

Participated in this study students and professors from the Institute of Biological and Health Sciences. The classrooms of the morning shift had the highest noise measurement. Classrooms at lunch time had the lowest average noise. The first floor has the highest average noise, being classified as the noisiest floor. Noise is perceived by both students and professors as an interfering factor in the activities performed inside the classrooms, however, professors have a greater perception of noise interference in their activities than students.

Noise is present in all classrooms with values higher than those recommended by national legislation. This noise is perceived by students and professors and negatively interferes in the teaching-learning activities.
