• Typical Classroom are 50-60 decibels • WHO says classroom noise goal = 35 db • WHO recommends an outdoor noise level of 45 db at night and 55db during the day • Typical classroom partitions should be STC50 • Average classrooms may be equipped for “zoned” acoustics to provide additional sensory cues for different educational zones. • Noises to think about: door slamming, PA noise, mechanical initiation, exterior noise intrusion, equipment sounds. • Employ sound masking to muffle environmental sounds
Exterior wall construction can be “tuned” to reach the right level of exterior noise resistance based on measured frequencies. ADHD: stochastic noise helpful for concentration ASD: intermittent noise harmful for concentration, speech clarity is a primary concern. SFA: sound field amplification
Acousticians to create a schedule of rooms and specific acoustical recommendations.
