* SIMON FRASER UNIVERSITY EDUCATION BUILDING EDB8620 RENOVATIONS ACOUSTICS RECOMMENDATIONS R1 FEBRUARY 15th, 2013 ACOUSTIC ABSORPTION WALLS The Faculty of Education has raised concerns regarding both the durability and the “pin stripe” surface pattern of the previously proposed Acoustic Wall Panel (AWP). Instead of the AWP the Faculty of Education would like to revisit cladding portions of the walls with Forbo Bulletin Board material as it is a self-healing tackable surface and provides moderate acoustic absorption. FLOOR/CARPET New carpet tile throughout the Interactive Space will provide some additional acoustic absorption. The carpet tile will be particularly good at reducing the volume of localized noise such as carts and chairs sliding across the æoor and footsteps of people walking through the space. CEILINGS To give EDB8620 a tall, lofty character solid suspended ceilings are limited to the perimeter of the space, leaving large portions of the Interactive Space and the Classrooms as tall as possible. 12 GA.

(BY INSTALLER) In the Classrooms and the Interactive Space the primary acoustic absorption is provided by an area of Acoustic Ceiling Grilles. The Acoustic Ceiling Grilles provide a relatively high NRC rating of approximately 0.80 and can be mounted close to the underside of the concrete slab which will help retain the ‘tallness’ of the space. In contrast to the existing rough sawn cedar plywood and the ‘fuzzy’ walls the linear grilles will provide a sophisticated and functional ånish. 1" REVEAL STANDARD 12" WIDE GEOPANEL GRILLE ACOUSTIC CEILING GRILLE ABSORPTIVE MATERIAL BEYOND WOOD GRILLE 2 DRAFT - FOR DISCUSSION BLACK A SELF-TAPPING F SCREWS R (BY Y INSTALLE REDUCED REVERBERATION TIME While there will be a signiåcant improvement in the overall acoustics relative to the existing EDB8620, it will not be possible to achieve the recommended reverberation times for educational spaces as outlined in ANSI/ASA S12.60-2010.
