Sound masking, speech privacy, and commercial audio for offices, clinics, and practices across central Indiana.
If you can make out the words of a conversation two desks away, so can everyone else — including patients in a waiting room, clients in a lobby, and staff who were never meant to hear it. Walls and panels help, but they stop being practical long before the problem is solved.
Sound masking raises the background sound in a space by a few decibels, using a spectrum engineered to sit exactly where human speech lives. Conversations don't get louder. They stop being intelligible. Most people describe the result as the room simply feeling calmer, and never identify the source.
Fewer distractions, less overheard conversation, and a measurable drop in how far a voice carries. Done properly, the system itself is inaudible.
Typically two to three dollars per square foot of covered area, installed and tuned. Restrooms, stairwells, and mechanical spaces don't need coverage, so the billable area is usually well under the floor plate.
No subcontracted commissioning, no crew that leaves the system at factory defaults. The tuning is the part that decides whether masking works or gets switched off six weeks later.
Site survey, emitter layout, installation, and zone-by-zone calibration to a target masking spectrum. You get a commissioning report with the measured curve for every zone, not a promise that it sounds about right.
Measurement of how intelligible speech is between spaces that need separation — exam rooms, intake desks, HR offices, conference rooms. Written findings you can hand to a compliance officer or a landlord.
Overhead paging and music zones on the same infrastructure as your masking system. If it's being installed anyway, adding zones costs a fraction of doing it later.
Absorption panels and ceiling treatment where masking alone won't finish the job, specified against what the room measurements actually show.
Rebalancing after a floorplan change, expansion into new suites, and bench-level repair of existing audio electronics. Systems we didn't install included.
Filament Acoustic is the commercial division of Filament, an audio electronics service company in central Indiana. Before this, the work was amplifier and synthesizer repair and backline production — the gear behind live sound, fixed at the component level.
That background is the whole reason this company exists. A sound masking system is a distributed audio system, and the step that decides whether it works is shaping noise to a target curve and balancing it zone to zone with a real-time analyzer. Most installers treat that as an afterthought. It's what we do for a living.
Badly tuned masking is why people think they don't like sound masking. It hisses, it's uneven, someone turns it down, and the investment quietly stops working. A system that's measured and documented doesn't have that problem.
Square footage and what's going on in the room is enough to start. Most assessments take under an hour on site.
