Prerequisite - Minimum Acoustic Performance (Schools)

Applies to: LEED® BD+C: Schools

Intent: To provide classrooms that facilitate teacher-to-student and student-to-student communication through effective acoustic design.

Requirements: HVAC Background Noise, Exterior Noise, Reverberation Time

Design classrooms and other core learning spaces to include sufficient sound-absorptive finishes for compliance with the reverberation time requirements specified in ANSI Standard S12.60–2010, Part 1, Acoustical Performance Criteria, Design Requirements and Guidelines for Schools, or a local equivalent for projects outside the U.S.

Classrooms and Core Learning Spaces:

< 20,000 Cubic Feet (566 Cubic Meters)

Option 1: For each room, confirm that the total surface area of acoustic wall panels, ceiling finishes, and other sound-absorbent finishes equals or exceeds the total ceiling area of the room (excluding lights, diffusers, and grilles). Materials must have an NRC of 0.70 or higher to be included in the calculation.

Option 2: Confirm through calculations described in ANSI Standard S12.60-2010 that rooms are designed to meet reverberation time requirements as specified in that standard.

20,000 Cubic Feet (566 Cubic Meters)

Meet the recommended reverberation time for classrooms and core learning spaces described in the NRC-CNRC Construction Technology Update No. 51, Acoustical Design of Rooms for Speech (2002), or a local equivalent for projects outside the U.S.

Focal Point Acoustic Solutions can contribute to achieving Reverberation Time requirements. See LEED® standard for information on HVAC Background Noise and Exterior Noise requirements.

The use of Focal Point Acoustic Solutions can contribute to reducing reverberation time (RT) to the maximum duration specified for each space. Please consult the test reports for each product where sound absorption averages (SAA), NRC, and sabin curves are found to calculate our products' contribution to a space to help meet Option 1 and Option 2, as well as requirements for spaces ≥ 20,000 cubic feet.

Please consult our product technical information for NRC values and acoustic testing reports, or reach out to our team of specialists for assistance with optimizing the acoustics of a space at acousticsolutions@focalpointlights.com.
