The system’s frequency and volume adjustment capabilities affect the ability to adjust the sound masking to accommodate the unique needs of each space.

Ask what kind of frequency (e.g. none, whole contour, 1 octave, or 1/3 octave control) and volume (e.g. large or fine increments) adjustment the system offers. Note the sound masking system’s adjustment flexibility is affected by the method of control and the zone size it offers.
