SmartSMS-NET – Soft dB’s Sound Masking System

1) Sustainability Problem – Sound Pollution at the Workplace

Average adults spend over 10.3 years (90,000 hours) at work in their lifetime and noise is one of the most common and yet least perceived occupational hazards. It causes hearing loss, anxiety, stress; it affects concentration, creativity and eventually productivity.

2) Technology – Soft dB’s sound masking system – SmartSMS-NET

According to Soft dB, the SmartSMS-NET emits a soft, inconspicuous background sound with the use of a loudspeaker system. The ambient sound level becomes more uniform and otherwise noisy distractions are muffled by the sound masking.

Soft dB’s sound masking system has three unique features:

  • Automatic Equalization Process

Masking sound level is adjusted automatically in real-time. A 340 narrow band equalization (instead of the usual 20 1 /3 octave bands) ensures the production of a uniquely smooth, regular and comfortable sound masking, irrespective of the acoustical characteristics of the workspace

  • Real-Time Adaptive Adjustment of the Masking Sound Level

The system continuously adjusts the masking sound level based on ambient noise measurement. In a busy work area, the masking sound increases, and decreases when the work area quiets down.

  • Networked System

The system is very flexible; it features small masking zones and larger masking zones. It combines the flexibility of network systems and the cost efficiency of centralized systems

The system has four main components: Speakers, Adaptive Sensors, SMS-NET Rack-Mounts and the SMS-Net


3) Organizational Stakeholders

  • Businesses
  • Schools
  • Courts
  • Counseling Centers
  • Public Institutions
  • Hospitals

4) Deploying the Technology

  • Consult with Soft DB about the specific needs of the environment at stake
  • Arrange for a physical evaluation to be conducted
  • Based on recommendation of consultants, discuss system with all relevant stakeholders and proceed to order system for installation

“The Zera Food Recycler requires a plant-based additive made out of coconut husk and baking soda to assist in the breakdown process.”
