How It Works
How It Works
- SonaRest generates continuous sound shaped to sit right in the 200-5000 Hz range where human speech happens.
- Place it just inside your door, facing outward, so it mixes with sound exactly where it would otherwise leak into the hallway.
- Set the volume 1-3 dB above normal talking so words blur into a gentle hum outside the room, while staying comfortable inside it.

What Makes SonaRest Built for Real Office Privacy?
Speech-Spectrum Sound Masking
Continuous sound tuned to the 200-5000 Hz speech range raises the noise floor just enough to blur words into a hum.
Natural, Non-Looping Sound
Non-looping playback means your brain stops noticing it within minutes, unlike buzzy digital tracks people complain about.
32-Step Precision Volume Control
Dial through 32 volume steps to match any room, from a quiet therapy office to noisy open-plan cubicles.
Built for All-Day Office Use
Built for 8+ hour daily use, the kind of workhorse reliability therapists expect to last for years.
What our 17,000+ Customers say
Based On Real and Honest Experiences
Clients used to hear the end of my previous session through the wall. I placed SonaRest just inside my office door and now conversations stay where they belong. My clients finally open up without whispering.
I run SonaRest on my desk to block open-office chatter all day. Unlike the buzzy machine I had before, this one just fades into the background within minutes. My focus, and my privacy, both improved.
Our walls are paper thin between therapy rooms. SonaRest set near the door made speech unintelligible in the waiting area within days. It's been running eight hours a day for months without a single issue.
Frequently Asked Questions
Does SonaRest actually stop people from overhearing conversations?
Does SonaRest actually stop people from overhearing conversations?
Yes. SonaRest raises the ambient noise floor 1-3 dB above normal speech in the 200-5000 Hz range, so words blur into a soft hum outside the room instead of staying intelligible.
Where should I place it so people outside my door can't hear me?
Where should I place it so people outside my door can't hear me?
Place SonaRest just inside the door, facing outward toward the leak path. That's the exact spot therapists recommend for masking conversations before they escape into hallways or waiting areas.
How loud does it need to be to actually mask conversations?
How loud does it need to be to actually mask conversations?
Acoustic research points to 45 dBA as the sweet spot for offices, loud enough to mask speech, not loud enough to annoy anyone. SonaRest's 32 volume steps let you land there precisely.
How is this different from a cheap looping white noise machine?
How is this different from a cheap looping white noise machine?
Unlike buzzy digital machines that loop and get noticed, SonaRest generates continuous, non-repeating sound your brain tunes out fast, the same quality professionals favor for daily office use.
Will one unit cover my whole office or therapy room?
Will one unit cover my whole office or therapy room?
Yes, for most rooms up to about 150 square feet. For larger suites or extra-thin walls, add a second SonaRest in the hallway or waiting area for full coverage at both leak points.
Do I need more than one machine for a larger office?
Do I need more than one machine for a larger office?
Add a second SonaRest in the hallway or waiting room. Two units placed at each leak point cover more ground than turning one unit up loud, and neither has to work overtime.
Will the sound itself annoy my clients or coworkers?
Will the sound itself annoy my clients or coworkers?
Rarely. At the right volume, SonaRest blends into a gentle background hum that people stop noticing within minutes, the opposite of overheard conversation, which always pulls attention.
What's the difference between white noise and sound masking?
What's the difference between white noise and sound masking?
White noise is flat static; sound masking like SonaRest is shaped to sit in the 200-5000 Hz speech range specifically, so it's tuned to make words unintelligible, not just add generic noise.
