Proposed state-of-the-art criteria for office building acoustics

G.E. Clunis


The author reports on the proposed criteria which have been collated and/or developed, including targets for: background noise (upper and lower limits); reverberation times; attenuation with distance; speech transmission coefficients; and office isolation. These criteria are presented for open and closed office space, and meeting rooms. Legal requirements are reviewed, and the unique requirements of hearing impaired occupants are also addressed. It is most important that PWC's criteria are realistic, and can be achieved within existing budgets, expertise, and equipment resources. The implications of these criteria in way of office fit-up are discussed, and in particular the impact that these criteria can have on other interior environmental performance indicators including indoor air quality (IAQ), thermal comfort, and illumination. Specific recommendations are given for ceiling systems, screens and partitions, and office equipment noise levels
