Sound Masking

Electronic sound masking systems raise the ambient sound level in offices to a controlled minimum sound level in order to increase speech privacy and reduce distractions. Sound masking systems are calibrated to provide the most uniform sound field achievable, as a spatially non-uniform masking sound field could result in occupant perception and uneven speech privacy conditions. Tolerances for acceptable spatial uniformity vary between specifiers, and may be based on different evaluation methods using only a few discrete measurement points to represent an entire office space. However, the actual uniformity of a masking sound field across an office, and the parameters influencing it, has not been widely investigated. Thus, this study aims to investigate the masking sound uniformity in a typical open-plan office space using fine-grid measurements conforming to measurement method of ASTM E1573-18. Percentages of measured locations where the sound pressure levels were within specified tolerances (with increments of 0.5 dB) were calculated using the measured 1/3 octave band levels. The research also utilized geometric acoustical simulations to investigate how physical office parameters (number of loudspeakers, partition heights, ceiling absorption, and diffusion characteristics) affect the sound field uniformity of the sound masking system.

Acoustic Conditions

Recently, many facilities have completed new laboratories that may be used to assess various measures of Indoor Environment Quality (IEQ) in office spaces. Also recently, a new standard, ISO 3382-3, was released for assessing the effects of speech on IEQ in open plan offices. The aim of this report is to assess one room of the IEQ lab using the ISO 3382-3 standard. It is expected that the data gained will be of help to researchers using the facility in the future.

A high percentage of information-based work is now conducted in open-plan offices as opposed to traditional cellular offices. In this systematic review, we compare health, work, and social outcomes as well as employee outcomes for workers in the two environments. From a total of 10,242 papers reviewed, we identified 31 papers which met strict inclusion/exclusion criteria of allowing a direct comparison between the office types. The results showed that working in open-plan workplace designs is associated with more negative outcomes on many measures relating to health, satisfaction, productivity, and social relationship. Notable health outcomes included decreased overall health and increased stress. Environmental characteristics of particular concern included noise and distractions, poor privacy, lighting and glare, and poorer temperature control. Most studies indicated negative effects on social relationships and interactions. Overall, the findings showed that while open-plan workplace designs may offer financial benefits for management, these appear to be offset by the intangible costs associated with the negative effects on workers. The study encourages further focused investigations into design factors as well as employee characteristics that might contribute to better outcomes in open-plan designs.

BACKGROUND: Open plan or open space office has become increasingly popular but those who promote the concept selfdom refer to health studies or workers’ perceptions of a change in office layout towards an open space arrangement. OBJECTIVE: To review the literature on open plan or open space office layouts in terms of facilities management (FM) with users’ perception in mind and to obtain opinions of users of open space offices of for a better appreciation of the FM issues. METHODS: A literature search of research papers from 2007 in journals using the keywords “open plan office” and “open space office” plus “health”, first in the titles then in the text, was carried out. Thirty-two of those papers, accessible by the authors’ institutions, were consulted together with 5 other works in the Harvard Business Review. The review consulted but excluded papers and reports published or sponsored by commercial firms that were in favour of open space layouts. Case studies were conducted by face to face meetings in confidence with workers in the middle managements of twelve Hong Kong organisations known as friends to two of the authors. Problems as seen by staff are reported and discussed. RESULTS: The literature review reveals that apart from writing that promotes the use of an open plan office layout, a host of scientific works point to the problems of perceived dissatisfaction with such a layout, the nature of the dissatisfaction tending to depend on the actual design. Most workers interviewed disliked the new style open plan layouts, which points to the necessity of consulting workers when such changes are contemplated, as well as monitoring the results of the change once it is in place whether against workers’ wishes or with their support. There is a need for a number of facility arrangements in making a change to open plan that ensures that worker needs for proper lighting, privacy, and indoor health will be met. CONCLUSIONS: If the aim of a change to an open plan arrangement is to promote collegial communications in office, the study sheds light on the extent to which such arrangements may not in practice be suitable for achieving the aim. It follows that further, more specifically sociological studies of workers’ job satisfaction and emotional health in open plan office settings would be worth doing.
