Include acoustic performance goals early in the design process to help keep this prerequisite cost-effective. Waiting to include acoustical strategies until after the building and mechanical systems have been designed can add significant cost to the redesign due to changes such as supply silencers, return silencers, duct layout reworking, lined ducts or flexible ducts, diffusers, lined sound boots, or double gypsum layers on fan-powered boxes. These strategies could be minimized or eliminated with early incorporation of acoustical goals.
