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.

Approach
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.
