For a panel to support the achievement of normal privacy, a NRC of 0.60 is recommended. More specifically, a panel should provide a Speech Frequency Sound Absorption average of 0.80 or greater. Certain furniture layout issues also contribute to the acoustical impact of systems furniture in open plan settings. When an open visual path exists between workers, sound can more easily pass along the same path and disrupt both. Provide a work station design which provides maximum enclosure and blocks, as much as possible, direct pathways for sound transmission.
Systems furniture works with other acoustical elements to ensure privacy and promote productivity.
A sound masking system is a precisely contoured, constant, broad band, low level background sound that masks conversational distractions and unwanted noise. It is similar to the sound of a HVAC system air diffuser. These systems generally consist of electronic devises which generate a sound signal, shape or equalize a signal, and amplify a signal. Sound masking systems are one of the more critical elements in preventing conversational speech from being a distraction in the work environment. They are necessary even when high performance ceiling systems and furniture systems have been installed because they ensure that when the variable air volume systems are moving low quantities of air, enough background ambient sound is present to prevent conversations from being overheard and understood.
