In classrooms and core learning spaces, keep HVAC background noise to 40 dBA following ANSI S12.60-2010, treat sites where the school-hours peak-hour Leq exceeds 60 dBA, and meet reverberation limits through absorptive finishes of NRC 0.70 or more equal to the ceiling area, ANSI S12.60 reverberation times, or the large-space table.
