Optimum Sound Masking Efficiency and Acoustical Comfort
SmartSMS is designed to provide the best masking sound while preserving the comfort of the occupants.
The precise adjustment of the masking sound is allowed by two unique features:
- Automatic Equalization Process: This ensures the generation of the desired sound masking spectrum for the
specific architectural characteristics of the building. The adjustment is quick and precise.
- Real-Time Active Adjustment of the Masking Sound Level: The masking sound level
is continuously adjusted, based on ambient noise measurement. In a busy work area, the masking sound increases. It decreases when the work area quiets down.
- The SmartSMS is an integrated centralized DSP-based system. The controller unit integrates all the required
components in a single unit: sound generator, equalization, amplification, internal clock and the active adjustment processor. The
loudspeakers are thus connected directly to the unit, thereby simplifying the installation, as well as saving time and space.
- Smart SMS includes graphical interface software which allows the entire adjustment, as well as a built-in real time 1/3 octave band spectrum analyzer that measures and verifies the conformity of the installation.
Smart SMS offers all these unique features at a very competitive price.
Why Has Soft dB Developed the Automatic Equalization of the Masking Spectrum?
The exclusive automatic equalization system of the Smart SMS allows the desired optimum sound masking spectrum to be generated,
with the optimization process controlled by the DSP, regardless of the geometrical and acoustical characteristics of
the room. This exclusive system guarantees the conformity and the quality of the generated masking spectrum in 100% of the
installations, without the trial and error steps.
With the Smart SMS, there is no more dissatisfaction and no more wasted time!
Why Do Some Clients Even the Most Renowned Ones, Appreciate the Sound Masking System While Other
Clients Are Dissatisfied with the Same Sound Masking System?
Because the rival sound masking systems are preadjusted for a
typical acoustic environment (eight-foot ceiling,
medium-quality carpet and ceiling tiles, four-inch ceiling space height, medium-density and medium-acoustic 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 differ from the
perfect masking spectrum. In that case, the system has to be adjusted in order to obtain the desired sound masking, 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, acoustic measurements have to be done with a one-third octave band spectrum analyzer. The
levels obtained for each one-third octave have to be compared with the ideal masking spectrum values and, finally, the masking
system has to be adjusted accordingly for each one-third octave. This process has to be done for every zone where the acoustic
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 requires a lot of time.
Also, in almost
all of the installations, the majority of the installers do the equalization by ear or, at the best, use only a sonometer to
obtain the approximate global level desired without considering the spectral content of the generated sound. The result
is often an inadequate sound spectrum and dissatisfied users. Also, several trial and error adjustment operations are needed.
These are expensive. Because of that, clients become dissatisfied with their new sound masking system.
THE SOLUTION
The Automatic Equalization of the Smart SMS eliminates these problems by generating the ideal
sound masking spectrum from the start-up of the system, no matter what the acoustic characteristics of the room may be. 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!
