For Schools
Teachers can’t teach and students can’t learn in noisy classrooms. The quality of the acoustic environment is vital to all
students since they must be able to understand the teacher to learn effectively. Selection of the proper acoustical treatments
can play a critical role in increasing the signal-to-noise ratio and reducing reverberation time. For details, click here.
LEED FOR SCHOOLS now recognizes that acoustics is an important element of indoor environmental quality. Here’s an overview of how ceiling
and wall systems contribute to the LEED for Schools acoustic credits. For details, click here.
EQ Prerequisite 3 – MINIMUM ACOUSTICAL PERFORMANCE
A minimum acoustical performance is required as a prerequisite. Design classrooms and other core learning spaces to meet the
Reverberation Time (RT) requirements of ANSI Standard S12.60-2002 (Annexes B-D 45 dBA) Also design classrooms and other core learning spaces to meet the Sound Transmission Class (STC) requirements
of at least 35.
The ANSI Standard S12.60 for Classroom Acoustics addresses the issues of both reverberation time and background noise and
their effect on speech intelligibility by placing maximum permissible levels on each. Armstrong has developed a simple reverberation tool to aid in your selection of materials to meet this credit
This interactive tool helps you calculate reverberation time and hear the difference in five simple steps:
- Describe the space
- See recommended guidelines
- Select surface materials
- The program will calculate the current reverberation time
- Select treatment materials for your space to meet the reverberation recommendation and hear the difference, before and after!
EQ Credit 9 – ENHANCED ACOUSTICAL PERFORMANCE
Enhanced Acoustical Performance - use same guidelines as above but meet a lower RT time (40 dBA - 1 pt.; 35 dBA - 2 pts.)
