The tremendous
flexibility of an open office floor plan makes it a logical choice for
many of today's businesses. However, there are some
trade-offs. One of the most common complaints by office personnel
is that they can hear conversations taking place three or four
workstations away. Besides being distracting, it also affects
productivity. Sound masking, when combined with the proper amount
and type of absorption (i.e. work station dividers, carpeting,
acoustical tile ceiling, etc.) can mask the human voice so that these
conversations become
unintelligible. By mounting speakers in the plenum (the area above
the lay-in tile ceiling grid) and driving them with a noise source
designed to mask the primary bandwidth of the human voice, it is
possible to achieve a degree of speech privacy. It is not uncommon
for a sound masking system to pay for itself in just one year due to
increased office productivity. With a minimal amount of additional
equipment and labor, background music and/or announcement, capability
can be layered on top of the sound-masking signal. Today,
businesses are realizing that a properly designed and installed sound
masking system allows them to profit from all the benefits offered by an
open office environment.
