Although it may seem like a small part of the project, correctly understanding impact insulation class/sound transmission class (IIC/STC) ratings as well as choosing acoustical underlayments can have an immense effect on the lifetime profitability of a project and value of repeat clients and customers.
When designing building entryways, especially highly visible and heavily trafficked ones, architects and specifiers must successfully achieve precision, performance, and beauty (the triple threat) simultaneously.
Metal ceilings can provide effective acoustical control along with eye-catching aesthetics, making them a versatile and functional design element. However, the panels must be perforated and backed with a sound-absorbent liner.
Specifying ceiling materials to achieve the best level of sound absorption is the correct starting point. However, ceilings alone are not truly capable of blocking enough noise between rooms to provide privacy and avoid annoyance. Additional steps need to be taken, either with the walls or with the plenum barriers, for effective sound insulation and to ensure background sound levels are within the desired range.
