Why are small zones important?
When a sound masking system’s adjustment zones are larger, the masking sound will fluctuate across your space as it interacts with elements of your workplace design—even if loudspeakers are set to the same volume and frequency.
And if you can’t make precise changes in specific areas, you’ll have to settle for setting each zone to a level that’s merely best on average.
Some large-zoned systems try to address this problem by providing audio transformers at each loudspeaker, but these can only offer coarse volume adjustments—and no control over frequency. No matter how you install the loudspeakers or what you try to do, large zones will create this effect.
Others direct their loudspeakers downward in a mistaken attempt to compensate for design factors influencing the sound. In reality, this approach simply doesn’t provide the control you need to get the best result.
