With the lack of standards to regulate classrooms in Colombia, we decided to find out what the current status was in terms of acoustical comfort. Due to the mild weather, classrooms usually do not have mechanical heating or cooling. For this reason, noise levels are mandated by proximity to busy roads or other noise sources. Their construction is typically done using heavy materials such as brick and concrete, which results in very low noise transmission, but Reverberation Times tend to be higher than recommended due to the little use of absorptive materials. Measurements and visual inspections were performed in several schools to evaluate these parameters against the current S12.60 ANSI standard.
