Classroom Noise, Ventilation, and Performance (01-11-24)
Bhandari and teammates link ventilation and noise and the cognitive performance of university students. They report that “focusing on ceiling fan noise in classrooms, this study investigates the effect of acoustic environment . . . on acoustic comfort, productivity, and engagement. A four-month-long field study was conducted in 11 naturally ventilated classrooms, obtaining 828 responses. . . . BGN [background noise] levels and RT [reverberation time] ranged from 58.2 to 65.3 dBA and 0.7–2.1 s, respectively.
