Speech Privacy · Sound masking that makes an open office feel private again.
Sound Masking System Installation for NJ, PA & DE
When every conversation carries, people stop talking and stop concentrating. We design, install and tune Biamp Cambridge sound masking systems across New Jersey, Pennsylvania and Delaware — from a single professional suite to a multi-floor campus. Every project starts with a free on-site assessment that includes an ambient noise measurement of your space.
If masking isn’t the right fix for your space, we’ll tell you that on the visit.

The short version
What a properly tuned system actually does
30 ft → 10 ft
A whisper that stays intelligible 30 feet away in a silent office becomes unintelligible at about 10 feet once masking is running.
45–48 dB(A)
The range we tune open office areas to. Roughly the level of quiet HVAC airflow — present, but not something you’d point at.
Class A / B
ASTM speech privacy configurations. We specify the class per area, based on how sensitive the conversations in it are.
Why people call us
Does any of this sound familiar?
Four complaints come up in almost every sound masking conversation we have. If you recognise two or more, masking is probably the cheapest fix available to you.
You can follow the conversation two desks over
In a quiet open plan, normal speech stays word-for-word intelligible 30 to 40 feet away. People notice, lower their voices, and eventually stop talking to each other.
Private calls aren't private
HR discussions, billing calls, patient intake and client conversations carry into hallways, waiting rooms and the offices next door — through doors and over partitions.
Nobody can concentrate
Intelligible speech is the most distracting sound in an office. It isn’t a volume problem — your brain is compelled to decode words it can understand, whether you want it to or not.
Someone is asking you about compliance
HIPAA, patient intake, financial advisory and attorney-client conversations increasingly need a documented speech privacy plan — not just a closed door.
How it works
Sound masking is not white noise
Sound masking adds a low, engineered background sound to a space, tuned specifically to the frequency range the human ear uses to decode speech. Nothing is cancelled and nothing is covered up. The background level of the room is raised just enough that speech beyond a short distance stops being intelligible — you can still tell someone is talking, you just can’t make out what they’re saying.
Acousticians call the distance at which speech becomes unintelligible the radius of distraction. In a quiet open office that radius can be 30 to 40 feet. A correctly commissioned masking system shrinks it to roughly the width of a workstation cluster.
✓ What it is
✕ What it isn't
The easiest way to understand it: think of a dishwasher running in the next room. You know someone is talking over it — you just can’t tell what they’re saying. Sound masking is that effect, engineered, at a level most people describe as quiet airflow rather than appliance.
The A-B-C framework
Absorb, block, cover
Speech privacy is never one product. The industry breaks it into three levers, and almost every space needs some of all three.
A — Absorb
Soft surfaces soak up reflected sound so it stops bouncing around the room: acoustic ceiling tile, carpet, wall panels, clouds and baffles. This is acoustic treatment, and it’s what makes a room sound calm.
B — Block
Physical barriers stop sound getting from one space to another: full-height partitions, insulated walls, solid-core doors, gasketing and plenum barriers above the ceiling line. Effective, but it means construction.
C — Cover
Sound masking raises the background level so whatever speech survives absorbing and blocking is no longer intelligible. It’s the only one of the three you can add to a finished, occupied building in a day or two.
The equipment
Three parts, and one of them is just network cable
Every system we install is built from the same three components, sized to the space.
Part 01
The controller
A Qt controller generates and shapes the masking spectrum, stores your zone levels and schedules, and drives paging or background music if you want them on the same system. Rack-mounted in your IT closet or wall-mounted in a utility space.
Part 02
The emitters
Small emitters sit on a grid above the drop ceiling, facing upward into the plenum so the sound arrives evenly and without a locatable source. Each one is individually addressable, so we can trim a single office without touching the rest of the floor.
Part 03
The cabling
The whole system runs on standard Cat5e or Cat6 home-run back to the controller. No speaker wire, no amplifier per zone. Adding an area two years from now is a cable pull, not a redesign.
The platform
Why we specify Biamp Cambridge
We’re a certified Biamp Cambridge Sound Management dealer. It isn’t the only masking platform on the market, but for commercial spaces in our region it’s the one we’ll defend in a bid.

Choosing correctly
Sound masking vs. acoustic treatment
These get confused constantly, and buying the wrong one is expensive. Here’s the honest split — and plenty of our projects end up being both.
| Dimension | Sound masking | Acoustic treatment |
|---|---|---|
| What it does | Raises the background level so distant speech stops being intelligible | Absorbs reflected sound so the room stops ringing and smearing speech |
| Where it goes | Emitters on a grid above the drop ceiling, plus one controller | Panels, clouds and baffles on walls and exposed ceilings |
| Best for | Open plan, private offices, waiting rooms, intake desks, call centers | Conference rooms, training rooms, cafeterias, gyms, hard-surfaced lobbies |
| Fixes | Speech privacy and speech-driven distraction | Echo, long reverberation, poor intelligibility, general loudness |
| Won't fix | Echo or a reverberant room — masking doesn't reduce reflections | Speech privacy on its own. Absorption rarely gets you all the way there |
| Disruption | Above-ceiling work, typically one to two days, no construction | Surface-mounted, so finish, fire rating and mounting need coordination |
Where we install it
Who Sound Masking Is Built For
Sound masking is most effective in spaces where speech privacy and concentration are business-critical. Law firms use it to protect attorney-client conversations. Healthcare providers use it to meet HIPAA privacy requirements for patient intake areas. Financial advisors and accounting firms use it to keep sensitive discussions from carrying across open-plan offices. Corporate HR departments use it so personnel calls stay between two people.

Budget
What sound masking costs
Nobody else in this market publishes a number, which is exactly why we will. These are honest starting brackets, not quotes.
Under ~3,000 sq ft
Small professional suite
A single controller and a handful of emitters covering a reception area, a few private offices and a small open area. Often addressed for a few thousand dollars installed.
~3,000–15,000 sq ft
A floor or a department
Multiple independently controlled zones, scheduling, and frequently paging on the same emitters. Priced by zone count and emitter count once the layout is set.
15,000+ sq ft
Multi-floor or campus
Networked controllers, a specified privacy class per area, and integration with existing paging, life safety or building systems. Phased installation is normal.
Four things move the number: total square footage, ceiling type (a standard drop ceiling with accessible plenum is the least expensive scenario), how many zones you want to control independently, and whether you add paging or background music. We don’t quote before we’ve measured — but you’ll leave the assessment visit with a budget range you can take to ownership, a finance committee or a board.
Our process
Five stages, and we measure at both ends
01
Assess
We measure your ambient noise level and note ceiling type, plenum depth, HVAC interference and network infrastructure. No charge.
02
Design
Emitter layout on a drawing, zones defined by how each area is used, and a target privacy class per zone.
03
Install
Our own crew, above the ceiling, after hours if you’d rather we weren’t in the way. No subcontractors.
04
Commission & tune
Levels set and verified with a meter zone by zone — typically 45–48 dB(A) in open areas — not left at a factory default.
05
Train & hand off
We show your facilities or IT contact how to adjust levels and schedules, and leave documentation. Then we’re a phone call away.

Questions we get every time
Sound masking FAQ
How loud is it? Will people notice it?
In an open office we tune to roughly 45–48 dB(A) — about the level of quiet HVAC airflow. Most people notice it for a day or two and then stop hearing it entirely. The giveaway is when the system is switched off: rooms suddenly feel uncomfortably exposed, and staff ask for it back.
Won't it just annoy my staff?
Badly commissioned systems do, and that’s usually a level problem or an untuned spectrum. Set correctly, masking reduces the thing people actually complain about — overhearing intelligible conversations. We tune zone by zone with a meter, and we come back and adjust after your team has lived with it.
Can it be turned down, scheduled or switched off?
Yes. Levels are set per zone and can run on a schedule, so masking drops or shuts off after hours and comes back before the floor fills. Facilities or IT can adjust it themselves; we show whoever owns the building systems how.
How is this different from a white noise machine from Amazon?
A consumer white noise machine produces untuned hiss from a single point in the room. It’s loud where you’re sitting, useless 20 feet away, and it doesn’t match the frequency range that makes speech intelligible. A commercial system delivers an engineered spectrum uniformly across an entire floor from dozens of emitters, at a level low enough that you stop noticing it.
That said, a single-room device is occasionally the right answer. If you are protecting one doorway or one desk rather than an open floor, see our guide to when a desktop sound masking device is enough.
Do I need a drop ceiling?
A standard drop ceiling with accessible plenum is the easiest and least expensive scenario, because emitters sit above the tile and fire upward. Hard-lid drywall and open or exposed ceilings are absolutely doable — they just call for a different emitter type and layout, which is one of the things we’re checking on the assessment visit.
Does sound masking help with HIPAA compliance?
It’s a recognised part of a speech privacy plan. HIPAA requires reasonable safeguards against incidental disclosure of protected health information — a waiting room where you can follow an intake conversation word for word is a real exposure. Masking is generally the least invasive and least expensive safeguard available in an existing building, alongside procedural changes.
How long does installation take?
A small professional suite is typically a single day. A full floor is usually one to two days, and larger buildings get phased so no department loses more than a day. Most of the work happens above the ceiling, and we’re happy to do it after hours or over a weekend.
