island ceilings :::: 15 oustical comfort olutions )r 'Retrofit' To meet acoustical rgulations, it is generally sufficient to provide the performance measures in unoccupied spaces, without office equipment switched on Acoustical regulations usually recommend values to be achieved for reverberation times (within a space) and sound insulation (between spaces or from outside the building) This approach isn't satisfactory any more to meet the expectations of occupants, in particular with the development of open spaces in offices and the increasing hearing problems of students in the education sector On a day-to-day basis, activities disturb the initial acoustical balance, for example group discussions, ringing phones, copier machines, music, open windows or road traffic noise Occupants of an office, a classroom, a shop, a hospital or any other space, need a comfortable and healthy environment to carry out their activity under the best conditions Acoustical retrofit solutions by Armstrong offer unique benefits Aesthetics: create a striking design and more intimate spaces 镕 Flexibility: solutions can be easily moved to suit future reconfigurations Functionality: act as light reflectors to minimise energy consumption Օ Ease of installation: special direct ceiling attachment (plasterboard and grid) with Optima Canopy What is 'retrofit'? An acoustical retrofit consists of fine tuning the acoustical performance of an existing space to meet the end users' desired levels of intelligibility, concentration and confidentiality When relocating a business to new premises or an existing office to suit new organisational requirements, acoustics must be taken into account as early as possible in the design process. Integrating acoustics and space planning will help achieve a good balance between space optimisation and occupants' comfort levels for more productive working environments. The acoustical performance of a space is set by its size, the room surface materials, furniture and background noise. An acoustical retrofit will therefore consider changing existing surface materials Օ complementing the existing room configuration with discontinuous ceiling solutions. Office space planning is a balance between optimising the area available and producing a comfortable and productive working environment. Armstrong recommends that acoustical fine tuning be considered as early as possible in the design scheme Islands ceilings: the Armstrong solution Plasterboard ceilings or exposed concrete soffits can create a very reverberant space which, in combination with today's office interior design trends with extensive use of glass partitions, impacts negatively on concentration levels. Existing suspended ceilings may not always meet the stringent acoustical requirements set by such applications as call centres. Treating sound directly above workstations, whilst also contributing to lowering the overall reverberation time, is then key to enhancing levels of concentration and confidentiality. Jnder challenging architectural and acoustica conditions retrofitting an existing ceiling with lightweight and designer acoustical absorbers or 'Canopies', can trigger a 180° shift in the perceived quality of the space, provide higher comfort levels and an increase in occupant productivity. Canopy solutions may further be complemented by wall treatments and active acoustics by Armstrong. Sabine dfinition A Sabine is a measure of the sound absorption provided by a material when installed within an architectural space. Canopies provide greater sound absorption than a traditional wall to wall ceiling of the same face surface area because the sound is absorbed from both the front and back surfaces of the Canopy Canopies installed in a typical 'lively' space will help reduce the reverberation time Sabine per unit is preferred to characterise the absorption provided by an individual 'space absorber', such as Canopies in Open spaces, open plan offices, retail outlets 镕 Corridors / lobbies Aactors that may affect the installed acoustica performance relative to the published results are Size of Canopies Օ Number of Canopies and their layout Suspension distance below a finished ceiling Օ Location and horizontal overlap of Canopy Ceiling tile selection (for Axiom Canopies) Example of acoustical treatment in an empty space: Acoustical performance objective: Speech intelligibility with a reverberation time (RT) <0,8s 3 2,5 cd ° 2 c/3 Room volume 250 m3 Ceiling height 2,6 m Area 96,2 m2 Length 12,0 m Width 8,0 m 11,5 0,5 Empty room 13 JLTIMA Canopy 20 OPTIMA Canopy 14 METAL Canopy 5 AXIOM Canopy (with JLTIMA OP) 0 250 500 1 000 2 000 4 000 125 Octave Band Centre Frequency (Hz)
