Specifying acoustic ceilings and HVAC equipment

Specifiers and architects seeking to ensure the mechanical equipment noise does not exceed the ceiling system’s ability to attenuate it can use a straightforward method defined in the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) Standard 885 (2008), Procedure for Estimating Occupied Space Sound Levels in the Application of Air...

Why fire sprinklers belong above suspended drop-out ceilings

Drop-out ceilings provide an alternative to ‘poke-through’ sprinkler installations and avoid the need to install drops from sprinkler mains so sprinklers can penetrate the ceiling and discharge water into the room below. This enables drop-out ceilings to be used in situations where penetrating sprinklers are not the optimum solution.

Specifying suspended acoustic baffles

While many design options exist (e.g. baffles, banners, islands, and clouds), the use of NRC rating as a performance metric does not. The sound-absorbing performance of these individual, hanging acoustic objects is not quantified using NRC. Instead, their absorption is characterized using sabins, the unit of sound absorption.

Room acoustics, sound control with metal panels

Metals do not only provide resilience, beauty, and acoustical performance, but gains in paint technology make for an unlimited resilient pallet for the design and viewing community. From a functional linear ceiling system to wall panel options, a building’s interior can benefit from the beauty and durability of metal.
