Modular classroom acoustics: Where we are and where we should be going.

This paper presents a review of an 18‐month study into the acoustical characteristics of modular (or relocatable) classrooms within the Omaha Public School District in Omaha, NE. The study included measurements of reverberation times, interior background noise levels (both occupied and unoccupied), and exterior facade sound insulation properties. From analysis of the gathered data, recommendations are made regarding sound insulation classification systems and background noise levels for the renovation of existing modular classrooms. These results may be used to inform the pending addendum to ANSI S12.60‐2002, regarding acoustic guidelines for modular classrooms. Suggestions for future research are also discussed.
