Objective and subjective evaluation of the acoustic comfort in classrooms
Applied Ergonomics, (2007)
Abstract
The acoustic comfort of classrooms in a Brazilian public school has
been evaluated through interviews with 62 teachers and 464 pupils,
measurements of background noise, reverberation time, and sound insulation.
Acoustic measurements have revealed the poor acoustic quality of
the classrooms. Results have shown that teachers and pupils consider
the noise generated and the voice of the teacher in neighboring classrooms
as the main sources of annoyance inside the classroom. Acoustic simulations
resulted in the suggestion of placement of perforated plywood on
the ceiling, for reduction in reverberation time and increase in
the acoustic comfort of the classrooms
