LOUDNESS LEVEL
The system can now be subjectively fine tuned for effectiveness and comfort. If the sound masking level
is too high, turn the volume control knob counterclockwise, in no more than fifteen minute increments,
until the desired loudness level is achieved. If the sound masking level is too low, turn the volume control
knob clockwise, in 10° increments, until the desired loudness level is achieved.

OCCUPIED SPACES
If masking sound is being added to an existing space that is currently in use, THE MASKING MUST BE
INTRODUCED SLOWLY, so that it won't call attention to itself. Therefore, once the initial installation is
complete, it will take weeks to bring the masking sound up to its recommended level for effective pri-
vacy. After tuning the masking as per the above procedure for unoccupied new space, record the final
settings for both the volume and equalizer controls. Indicate on the bottom of the DS1042 unit, with a
permanent marker, the recommended settings.
INITIAL MASKING LEVEL SETTINGS FOR OCCUPIED SPACES
If you have a sound level meter, measure the existing ambient background in several areas and record the
lowest reading. Then go to the DS1042 unit and set the volume so that the masking level is 2 dBA above
the lowest ambient reading that was recorded. If you do not have a sound level meter, set the volume
control on the DS1042 unit to the 60° position.
RAISING THE INITIAL MASKING LEVEL SETTINGS IN OCCUPIED SPACES
After a continuous Monday-to-Friday cycle of non-interrupted masking at the initial setting, raise the
masking level 2 dBA or about 10° on the volume control from the initial setting. This increase in level
must be done on Friday at the end of the work day, after most of the employees have left the building.
Continue this weekly increase until the most desirable setting as determined above is met. If there are
objections about the masking level being too high, as the system is being raised to its final design, re-
duce the volume by 4 dBA (or 15°) on the volume control. Leave the masking level at this setting for two
(2) weeks, and then begin to adjust the masking level higher again as per the above technique until the
acceptable level is reached.
