Sound Control Movable Wall Dividers

In architectural acoustics, we are concerned with controlling the duration of sound. In the walls and movable dividers partitions, this is done by controlling the sound transmission loss. At present, the most widely accepted acoustic performance ranking standards are STC or Rw. The sound transmission class is a two-digit number that describes the laboratory performance of a single building element that prevents sound transmission when passing through.

The following diagram is a rough guide of the privacy implications of various STC levels, which helps to understand why you need dividers movable sliding walls.

STC privacy

• 55 shouting not audible
• 50 shouting barely audible
• 45 loudly speech barely audible
• 40 loud speech audible, but can not understand
• 35 Loud speech understood
• 30 Normal speech audible, but can not be understood
• 25 normal speech easy to understand

The intended use of the room and the surrounding area will determine the amount of sound control you need. For example, movable room divider that separate a high school science classroom from student labs do not need to be as good as the movable room dividers of the hotel’s conference rooms.
