Auto Equalization Process

Ease of installation is what sets Smart SMS apart from its competitors. Smart SMS is the only sound masking system that can automatically adapt to any room or office space by using advanced digital signal processing. How Does It Work? The automatic equalization system (patent pending) is based on the measurement of the room response. Using the power of the DSP and advanced signal processing, the Smart SMS has an integrated automatic process that:

  • Measures the room acoustic response
  • Measures the background noise
  • Calculates the exact signal to generate the desired sound masking

Features & Benefits
  • The automatic equalization of the system is done by using a PC connected to the Smart SMS unit. Upon opening the Smart SMS software, the main interface window is displayed.
  • By pressing the Start Averaging button, a white noise is generated by the speakers in the room. A calibrated reference microphone (included with the Smart SMS software) is used to measure the resulting noise spectrum in the room, and the software automatically calculates the room response. The process lasts only a few seconds.
  • Then, the Smart SMS measures the background noise level with the same reference microphone.
  • Once these measurements are done, the Test Calibration button generates the exact sound masking1 desired in the room.
  • By moving the microphone around the room, the resulting sound masking spectrum generated in the room is displayed on the PC with the real-time spectrum analyzer included in the Smart SMS software. If desired, the same process can be carried out for a specific zone in the building, which may have different room responses. One Smart SMS unit can use up to 8 channels for different room acoustic responses.
