Some tasks require higher levels of concentration than others and the acoustic environment of an open plan office can cause too much disturbance. What is needed is a special room – a quiet room. Requirements for a quiet room vary from person to person, as we all have different needs for calm in order to concentrate. A quiet room must allow you to achieve maximum concentration and hold private conversations. Several people usually have access to the quiet room, so the work environment should be adapted to the person with the most stringent requirements.
A quiet room places great demands on both sound absorption and sound insulation. As the room is not a workplace for any one individual, the walls are often bare, which can create sound reflections and long reverberation times.
Disturbing noise from outside affects a person's ability to concentrate and the need for privacy is often vital.
The goal should be maximum sound absorption - class A.
Sound insulation of 40-44 dB (laboratory value) is recommended, depending on the level of privacy required. Remember that doors and glass partitions must also meet these requirements. Do not place a quiet room near service installations if possible.
- to always achieve sound absorption class A and shorten the reverberation time and reduce background noise.
