Abstract/OtherAbstract:
This research is a case study developed to evaluate and compare the classroom acoustics of two different buildings from the Federal University of Paran, built in different times: Building CP (from the 1960s) and building JB (built in 2000). Acoustical parameters have been measured in eight classrooms of the CP building, and seven classrooms of the JB building: Sound pressure level, reverberation time, and sound insulation. The methodology employed followed standard procedures for acoustical evaluation of classrooms. Results showed that the classrooms of the CP building, from the 1960s, display satisfactory acoustical conditions, especially in their reverberation times. On the contrary, classrooms of the more recently built JB building yielded poor results with respect to reverberation times, either in empty classrooms, or in partially or even totally occupied classrooms, not meeting the values set by the standards. Thus, despite the evolution of the studies and research on room acoustics, older classrooms of the Federal University of Paran have better acoustics than more recently built classrooms.
