The use of free-hanging units provides flexibility and a multitude of acoustical solutions to problems related to acoustical design. Where free-hanging units are used to improve poor acoustics, solitary units give the benefit of diffraction effects, with a larger area of the absorbing patches being exposed to the sound field. Both effects can be used to increase sound absorbing properties.
In large, noisy environments such as open-plan areas, restaurants, shopping centres etc., free-hanging units can be installed close to working areas or other locations where acoustical treatment is needed in order to achieve suitable conditions for communication, concentration or recovery. such areas can be, for instance, reception and information counters or refreshment areas, included in larger, noisy spaces. prolad raft are engineered acoustical products with an all- round scrim facing, finish giving exceptional levels of acoustic performance and high light reflectance. Ideal for noisy environments where traditional acoustic ceilings are either not possible due to structural design limitations or cannot provide the high level of performance required. Acoustic rafts provide an economic solution with an attractive float’s in the ceilings, a modern visual to enhance todays building interiors. Around an free-hanging unit, the acoustical effect is manifested as:
- Noise reduction in the vicinity of Free-hanging units
- Increased speech intelligibility and C50
- Shorter early decay time (EDT)
- Increased directional hearing
