8 out of 10 employees believe they could be more productive
in a quieter environment. Noise reduction reduces stress and
improves employee morale. In addition, sound masking prevents
private information from being overheard by the wrong person.
many offices utilize fabrics, flooring, and ceiling tiles
to absorb sound, this often is undermined by furnishings and
workers who personalize their offices with reflective materials.
Sound masking systems utilize speakers in the ceiling plenum
or open space that are designed and tuned to eliminate specific
types of noise when it is traveling in the air.
than drowning out the unwanted noise, sound masking literally
creates a contoured, consistent broadband, low-level background
sound that neutralize the distracting sounds. Systems are
typically set at a sound level of NC 40, which corresponds
to 48 decibels (dBA) +/- 2db. Zone output is controllable
in nominal levels such as 1.5 dB increments.
sound masking systems assure the maximum degree of speech
privacy at the lowest possible background sound. Unlike a
fixed sound masking spectrum for all applications, our installations
precisely fill in one-third octave band attenuation deficiencies
for the specific application, and generate and contour a precise
computer generated sound masking spectrum for optimum performance.
Acoustical privacy is accomplished by a combination of voice
levels, sound attenuation, and background levels. The sound
attenuation factor is a property of the building structure
and cannot be changed, once installed. The background sound
levels are set with a masking sound spectrum that is designed
to complement the sound attenuating factors such that a specific
degree of privacy is obtained.
