Be strategic about adjacencies, think about where meeting rooms are in relation to predictably noisy and other noise sensitive spaces, including vertically! Noisy spaces above and below meeting rooms are a common problem.
Short ductwork between spaces are a common cause of unwanted sound transmission. When designing new spaces consider duct routing to minimize this concern.
Avoid positioning adjacent meeting rooms 'back to back' (screen wall to screen wall). This increases risk of noise transfer between meeting rooms.
Key Hints
Bad adjacencies or inadequate acoustic separation risks a lack of privacy, and frequent noise interruptions. Even small distracting noises can be enough to throw attention away from the task at hand!
