Watch how SmartSMS-NET works
A short product overview showing how Soft dB's adaptive sound masking makes offices quieter and more private — without you noticing it's running.
— THE TECHNOLOGY —
What is Sound Masking?
A uniform, neutral, non-disturbing background sound that covers distracting conversations and noises — making them less intelligible and less disruptive without making the space silent.
Uniform Spectrum
Engineered 1/3-octave spectrum, evenly distributed across every speaker zone.
Unobtrusive Airflow
Sounds like gentle HVAC airflow — users stop consciously noticing it within minutes.
Speech Privacy
Speech becomes unintelligible at 15–40 ft from the source — no isolation walls required.
NOT Cancellation
Sound masking adds a managed background layer — it does not subtract sound like noise-cancelling headphones.
— PROVEN RESULTS —
The "Perfect" zone · 40–50 dBA
SmartSMS-NET tunes your background sound level to the precise zone where masking works without becoming a distraction. ±1 dB precision — measured and calibrated per zone.
— DISTRACTION RADIUS —
Cut distraction radius by 62%
You overhear conversations from far across the floor — concentration broken constantly.
Speech becomes unintelligible past 15 ft — desk-level privacy without walls.
— SMARTSMS-NET ADVANTAGES —
Why SmartSMS-NET?
Networked, adaptive sound masking with patented automatic calibration — the 3rd-generation controller platform.
Adaptive Volume
Real-time measurement of ambient noise. The masking level adjusts gradually — louder during busy periods, softer in quiet times — for continuous comfort and effectiveness.
Automatic Calibration
Patented (US 7460675 B2): measures each room's acoustic response and background noise, then computes the optimal masking spectrum per speaker zone. ±1 dB precision · 1 min per zone.
Networked Multi-Zone
WiFi, LAN, or USB connectivity. Each speaker zone is independently controllable. Aux inputs for paging or music. Touch-screen, mobile app, or LAN control.
— SMARTSMS-NET CONTROLLERS —
From small office to enterprise floor
Four controller models scale from 12-speaker compact deployments to 600-speaker rackmount installations.
Enterprise Tier — Touch-Screen Rackmount
Standard 1U rackmount with on-device touch-screen. RL96-8ch: 8 channels × 12 speakers/channel = 96 speakers. Or pair with RLCTL2 + external amplifier for up to 600 speakers across 8 line-level outputs.
— PATENTED TECHNOLOGY —
Two systems, one objective
Calibrate once, adapt forever — the SmartSMS-NET controller continuously balances comfort and efficiency.
Automatic Calibration
- ◆ Measures each room's acoustic response
- ◆ Captures the background noise spectrum
- ◆ Computes the optimal masking spectrum across 1/3-octave bands
- ◆ Adjusts each speaker zone independently
- ◆ ±1 dB precision · ~1 minute per zone
Adaptive Adjustment
- ◆ Continuously measures ambient noise via ceiling-mounted sensors
- ◆ Masking volume tracks office activity — louder when busy, softer when quiet
- ◆ Adjustments only for sustained variations — never for sudden spikes
- ◆ Gradual ramps — virtually unnoticeable to occupants
- ◆ Maximizes both comfort and masking efficiency
"People exposed to level-adaptive sound masking felt less tense, nervous, and stressed than those who did not receive the intervention."
How adaptive volume works in hardware
— REAL DEPLOYMENT —
From design to installed system
An example multi-zone deployment: a single corporate floor with 8 acoustically distinct zones (color-coded), 55 ceiling speakers, 8 ambient noise sensors, and one rackmount controller managing them all.
— USE CASES · EFFECTIVE AT THE RECEPTOR LOCATION —
Designed for spaces where privacy & focus matter
Open-Plan Offices
Cut distraction between adjacent workstations (15–40 ft range).
Private Offices
Speech privacy at the door — no overheard meetings.
Waiting Rooms
Conversations at reception don't reach seated visitors.
Reception Areas
Lobby calm — guests don't overhear front-desk calls.
Patient Rooms · Clinics
HIPAA-style confidentiality at bedside & in corridors.
Call Centers
Reduce inter-agent crosstalk; improve call clarity.
Banks & Finance
Counter & meeting-area confidentiality.
Outside Conference Rooms
Effective at the receptor — eavesdroppers hear noise, not words.
— ADDITIONAL CAPABILITIES —
More than masking — a full audio platform
Save $8/sqft
Cuts soundproofing costs — fewer plenum barriers, less insulation, no extra drywall.
Music & Paging Aux
Auxiliary inputs route through the same speakers — no second system needed.
Ramp-Up Timer
Gradual morning start — masking fades in to match occupancy.
7-Day Schedule
Office hours, weekends, holidays — fully programmable.
iOS / Android App
Adjust zones, change schedules, paging — from any phone on the network.
Touch-Screen (RL96)
Rackmount controller with on-device touchscreen — no PC required for daily tasks.
Full Network Control
LAN + WiFi connectivity. Manage multi-floor deployments from one console.
Plenum-Rated Hardware
Compact ML-series fits inside ceiling plenum — no equipment closet needed.
— TRUSTED GLOBALLY —
Optimized 13M ft² · every year
From Google offices to Buckingham Palace — Soft dB sound masking technology runs in workplaces across 5 continents.
"Soft dB sound masking system is an absolute pleasure to work with. I have personally operated many sound masking systems in the past and never experienced something so user-friendly with almost unlimited system functionality."
"Soft dB system and installation plan met our challenging space requirements. I'm very pleased with how our sound masking system is working, as it is making a positive impact on the quality of our work environment."
— FREQUENTLY ASKED —
Quick answers about sound masking
Is sound masking the same as noise cancellation?
No. Noise cancellation actively subtracts sound (used in headphones). Sound masking adds a precisely engineered background sound to cover existing distractions, making them less intelligible — without making the room silent.
How loud is it? Will employees notice?
Sound masking is engineered to sound like gentle airflow — most occupants stop consciously noticing it within minutes. The adaptive system raises and lowers the level gradually based on ambient activity, so changes are imperceptible.
How long does installation & calibration take?
Speakers install in the ceiling plenum during off-hours. Patented automatic calibration takes about 1 minute per zone — typical floors are calibrated in under an hour.
Can I control it remotely / from a phone?
Yes. SmartSMS-NET ships with iOS and Android apps, plus LAN / WiFi / USB connectivity. The RL96 rackmount controller also has an on-device touch-screen for daily operations without a PC.
What dB level is optimal?
40-50 dBA is the optimal range. Below 40 dBA the background is too low to mask speech effectively. Above 50 dBA the masking becomes noticeable and causes fatigue. SmartSMS-NET calibrates to ±1 dB precision.
