Recommended Volume Settings Based on Performance:
If you have a sound level meter, the ideal sound level in private offices is 42 dB. The ideal sound
level in open areas is 46 dB.
If you do not have a sound level meter, have someone in the adjacent private office speak. If you can
distinguish what they are saying, increase the volume to improve privacy. In an open area, you will
still hear some speech, but there should be a noticeable difference in the effort required to
understand the speaker when the sound masking system is set at the appropriate volume level.
Some personal preference may be involved in the volume-setting decision.
• For installation in new construction
: Initial volume setting should be the specified setting.
• For installation in occupied spaces
: Initial volume setting should be two (2) steps below the
recommended level. Volume levels should be increased one step every 5 – 10 days, when few
or no employees are present. This allows all employees to acclimate to the new background
sound and significantly improves user acceptance.
Once volume level has been set, fill in Volume Setting field on the control module label(s).
