The Basics

What Is Sound Masking?

One of the most common misconceptions is that sound masking is simply white noise. It isn't. A commercial sound masking system produces a carefully engineered background sound that blends naturally into the workplace. Rather than making an office louder, it reduces the contrast between conversations and the surrounding environment, making speech less intelligible at a distance.

Employees often notice that the office feels more comfortable, even if they don't consciously notice the sound itself. When properly designed and tuned, sound masking can help improve speech privacy while reducing distractions in open workspaces.

Soft dB Speakers

The Right Speaker For Every Ceiling

Soft dB builds one of the widest sound masking speaker ranges on the market, so the design can follow your ceiling instead of fighting it — plenum, exposed structure, drywall or raised floor. We specify, install and tune all three families.

Soft dB SMS-STR upward-firing sound masking speaker in matte white
Open ceiling & plenum

Soft dB SMS-STR

An upward-firing speaker that reflects masking sound off the deck, draping the whole room in a smooth, diffuse sound layer. Works suspended in the plenum or hung in an exposed ceiling.

  • Perfectly diffuse masking sound — no dead or hot spots
  • Crisp paging and background music distribution
  • Built-in rotary power-tap selector for per-speaker level trim
  • Compliant with City of Chicago Environmental Air (CCEA) regulations
  • Matte white and black finishes
Soft dB SMS-STX low-profile sound masking speaker with Lexan polycarbonate shell
Low-profile plenum

Soft dB SMS-STX

Same acoustic performance and uniformity as the SMS-STR in a footprint roughly 40% smaller and 35% lighter, driven from 25V constant-voltage lines by Soft dB multizone controllers.

  • Runs on 25V constant-voltage lines from smart multizone controllers
  • Lightweight, durable Lexan polycarbonate shell
  • Phoenix connector blocks for clean, error-free wiring
  • Minimal visual impact in exposed-ceiling designs
  • SMS-STXATT plug-in attenuator for individual level trim
Soft dB SMS-SURF4 flush-mount direct field sound masking and paging speaker
Direct field & paging

Soft dB SMS-SURF4

A compact flush-mount speaker for drywall or suspended gypsum-board ceilings and offices with limited plenum space, where paging loudness and clarity matter most.

  • Ideal where masking alternates with paging and background music
  • 25V/70V constant-voltage amplifier compatible
  • Daisy-chainable for very large installations
  • Built-in rotary power-tap selector
  • CCEA compliant

Up-firing plenum speakers deliver the most uniform masking across a space — Soft dB's InterNoise research showed spatial uniformity holds up even when the plenum is obstructed. Down-firing direct field speakers make more sense with drywall or gypsum-board ceilings, or where paging must be loud and clear. Product imagery courtesy of Soft dB.

Why Businesses Invest In Sound Masking

Designed For Collaboration — Not Always For Privacy

Today's workplaces are designed for collaboration, but many were never designed for acoustic privacy. Employees working in open offices are constantly exposed to nearby conversations, ringing phones, meetings and other background distractions. Even small interruptions throughout the day can reduce concentration and productivity.

Improve Speech Privacy

Reduce how easily nearby conversations can be understood from surrounding work areas.

Reduce Workplace Distractions

A more consistent acoustic floor means fewer sudden noises pulling attention away from focused work.

A More Comfortable Environment

The office feels calmer and less fatiguing, even when the space is busy.

Support Focused Work

Employees can concentrate longer without being interrupted by every nearby conversation.

Improve Customer Confidentiality

Protect sensitive conversations at reception counters, teller windows and private offices.

Reduce Noise Complaints

One of the most common post-move complaints — overheard conversations — is directly addressed.

Enhance Employee Satisfaction

A quieter, more private workplace consistently rates higher in employee experience surveys.

Support Professional & Healthcare Privacy

Help meet the privacy expectations of legal, medical, financial and government environments.

Where It Works Best

Environments That Benefit The Most

Sound masking can be used in many commercial environments where conversations need to remain more private or where reducing distractions improves the workplace experience.

Corporate Offices

Open office layouts benefit from improved speech privacy between workstations while helping employees stay focused throughout the day.

Healthcare Facilities

Medical offices, clinics and healthcare environments often use sound masking to help support patient privacy in waiting rooms, examination areas, administrative offices and reception spaces.

Law Firms

Attorney-client conversations often involve sensitive information. Sound masking can help reduce the distance conversations travel outside offices and conference rooms.

Financial Institutions

Banks, wealth management firms, insurance agencies and accounting offices frequently install sound masking to improve privacy during financial discussions.

Government Buildings

Many government agencies use sound masking in public service counters, administrative offices, interview rooms and conference spaces where confidential conversations occur.

Call Centers

Customer service representatives spend much of the day on the phone. Sound masking helps reduce distractions while making nearby conversations less noticeable.

Conference Rooms

Conference rooms located next to open workspaces often benefit from sound masking by helping reduce sound transmission into adjacent areas.

Our Design Process

Every Office Is Different — Every System Should Be Too

No two sound masking systems should be identical. Our process begins with understanding how your employees use the space and identifying areas where speech privacy or workplace distractions are affecting productivity.

  1. Step 01

    Site Survey

    We evaluate the office layout, ceiling construction, workstations, conference rooms, collaboration areas and other spaces where sound masking may be beneficial.

  2. Step 02

    System Design

    Using the floor plan and workspace layout, we design speaker locations and system zones that provide consistent coverage throughout the office.

  3. Step 03

    Professional Installation

    Our technicians coordinate installation with your project schedule while minimizing disruption to normal business operations.

  4. Step 04

    System Tuning

    After installation, the system is adjusted for the specific environment. Proper tuning is one of the most important parts of a successful sound masking installation.

  5. Step 05

    Training & Support

    We walk your team through system operation and remain available for future adjustments as your office evolves.

Does it work with exposed ceilings?+

Yes. Speaker selection and installation methods vary depending on the ceiling type and office design.

Will employees hear it?+

Most people notice the workplace feels more comfortable rather than noticing the sound itself. Proper tuning is essential.

Can it improve speech privacy?+

Sound masking helps reduce how easily conversations can be understood from surrounding work areas. Every office is different, and results depend on the building layout and acoustic conditions.

Does it interfere with Microsoft Teams or Zoom meetings?+

No. Properly designed systems are intended to improve the workplace environment without interfering with normal conversations or virtual meetings.

Can installation be completed after business hours?+

Yes. Many projects are scheduled during evenings, weekends, or phased construction to minimize disruption.
