Ceilings
as Acoustically
Functional Elements
In order to create a comfortable acoustic environment in a space, it is necessary to solve two interrelated problems: First, the space needs to be protected from unwanted external sounds, and second, the sounds generated within the room must be reduced to only those sounds which are useful and desirable. This is done by reducing or eliminating echoes, white noise from machinery, and random sounds from human activities in the room.
--William Morris (1834-1896) English architect, furniture and textile designer, artist, writer, socialist and Marxist associated with the Pre-Raphaelite Brotherhood and the English Arts and Crafts Movement.
Satisfactory sound insulation can be achieved using massive materials with superior sound insulating properties, or by using thicker walls and ceilings.
The case is somewhat different for noise absorption. While sound absorbing materials such as carpets and upholstery usually take care of echo in residential spaces, commercial, institutional, and educational spaces require hard surfaces, both for cleaning and durability reasons, and also because of building and fire codes. Extensive carpeting and fabrics can be hazardous in a fire, and can accumulate dust and other allergens. Long drapery can also be a tripping and security hazard. Special acoustic panels are often installed on walls and ceilings in public buildings for these reasons, but these can be a source of frustration to designers attempting to create a warmer, more ‘homey’ or more natural
ambience.
A design opportunity that is often missed in such spaces is that presented by the ceiling. While nominally functional in controlling noise, acoustic tiles generally lack the “wow
factor” that professional designers strive for. Other options are becoming available, and one of the best is acoustic perforated stretch
ceiling.
