Why Is the Smart SMS Sound Masking System the Best on the Market?
- Because the Smart SMS is the only sound masking system with an exclusive auto-calibration algorithm (patent pending 2,471,674) that
ensures the exact desired sound masking spectrum (please consult What is the optimum sound masking?).
- Because the Smart SMS includes an advanced signal-processing procedure that automatically adjusts the volume
of masking, higher or lower, depending on the intensity of conversation noise and other noise distractions.
- Because the Smart SMS is the only sound masking system with a built-in real time 1/3 octave band spectrum
analyzer that measures and verifies the conformity of the installation.
- Because the Smart SMS offers these unique features at a very competitive price.
Why Has Soft dB Developped the Automatic Calibration of the Masking Spectrum?
The exclusive auto-adjustment system of the Smart SMS allows, with the optimization process controlled by the DSP,
to generate the optimum sound masking spectrum wanted, no matter what are the geometrical and acoustical characteristics of
the room. This exclusive system guarantees the conformity and the quality of the masking spectrum generated in 100% of the
installations without the trial and error steps.
With the Smart SMS, no more disatisfaction and no more waste of time!
Why Do Some Clients Appreciate the Sound Masking System, Even the More Renowned Ones, While Other
Clients Are Dissatisfied with the Same Sound Masking System?
Because the rival sound masking systems are preadjusted for a
typical acoustical environment (eight-foot ceiling,
medium-quality carpet and ceiling tiles, four-inch ceiling space height, medium-density and medium-acoustical characteristics
of the furniture, etc.)
1. If the fitting-out of the room is different from the typical
case (ceramic floor or no suspended ceiling, for example), the sound spectrum generated in the room will wander from the
perfect masking spectrum. In that case, the system has to be adjusted in order to obtain the sound masking wanted, not only
in terms of global sound pressure level, but also in terms of spectral content.
In all rival masking systems on the market, this adjustment has to be done manually. To do the adjustment properly, i.e. to
obtain the ideal masking spectrum, acoustical measurements has to be done with a one-third octave band spectrum analyzer. The
levels obtained in each one-third octave has to be compared with values of the ideal masking spectrum and, at last, the masking
system has to be adjusted accordingly for each one-third octave. This process has to be done for every zone where the acoustical
room response is different (entrance hall, open-plan offices, private offices, meeting rooms, etc.).
The adjustment of the typical sound masking system is a tedious and delicate task that needs a lot of time.
Also, in almost
all of the installations, the majority of the installers do the calibration by ear or, at the best, use only a sonometer to
obtain approximately the global level wanted without considering the spectral content of the generated sound. The result
is often inadequate sound spectrum and dissatisfied users, Also several adjustment operations of trial and error are needed.
These are expensive. Because of that, clients are discontended of their new sound masking system.
THE SOLUTION
The automatic calibration of the Smart SMS eliminates these problems by generating, from the start-up of the system, the ideal
sound masking spectrum no matter what are the acoustical characteristics of the room. This is a unique advantage that
facilitates the installation, reduces cost and ensures the satisfaction of the clients.
The Smart SMS system redefines the standards of quality in the sound masking industry!
