• Arrange classroom furniture away from noise sources
• Attached rubber stripping to classroom doors
• Replace ceiling tiles with models that reduce noise
• Lower ceiling height by adding acoustical panels (9-12 feet is optimal)
• Install carpet over a pad (IAQ issues may be a risk)
• Open grilles and diffusers wider
• Rebalance the heating and cooling system to reduce the amount of air provided to a space
