Office workers are often involved in projects and team assignments. To succeed, the team needs to transfer knowledge within the group and have meetings, discussions and work sessions. Preferably, this is done in a space separate from others, but it often takes place in a semi-open space or among others in a completely open space.
In a project room it is important to hinder wall-to-wall echoes and support communication (speech clarity). The room should also be properly sound-insulated to keep sound from entering or leaving the space.
In a semi-open or open space you need to keep sound from spreading, prevent sound levels from escalating and avoid the need for people to raise their voices. The team should have local speech clarity so they can talk normally.
A project room needs sound insulation, a sound-absorbing ceiling with good absorption qualities at low frequencies, and wall absorbers.
In a semi-open or open space you need a sound-absorbing ceiling with good absorption qualities at speech frequencies, and if people in adjacent areas can be disturbed, sound-absorbing screens.
