Signal to Noise Ratio—Noise intrusion and the level of acoustical privacy between work spaces, in either open or closed plan, is determined by the degree to which the sounds from a nearby work space exceed the background sound levels. It is essential that both the spread of sound from voices and other sources and the background sound are carefully controlled.
General Goals—Acoustical ceiling finishes for open-plan and closed offices should be selected to achieve the chosen office acoustics design requirements, including maximum limits for reverberation times. Ceiling finish material options can include suspended acoustic tile ceiling systems, baffles, banners, and clouds. Acoustical ceiling finishes for open-plan offices are additionally chosen to reduce noise levels generated by activities, and to improve speech privacy between work stations by reducing direct and reflected sound propagation. Goals for designs of ceiling finishes in closed offices, meeting rooms, training rooms, and conference rooms include the optimizing of speech intelligibility within the space. Further goals of the design of a continuous suspended ceiling system can be to attenuate sound emitted from plenum-installed ducts and mechanical components, and to attenuate airborne and impact sound generated on the building floor above.
