For the price, SonaRest outperforms every app and plug-in machine I've tried. The rechargeable battery alone saves me from buying disposables, and the sound quality is noticeably richer than my phone speaker ever managed.

Based On Real and Honest Experiences
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.

Six months in and my SonaRest still runs like day one. I travel with it every week for work — hotels, Airbnbs, even a camping trip — and it consistently delivers the same deep-sleep experience no matter where I am.

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
+212 expertsreviewed itYes. 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.
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.
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.
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.
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.
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.
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.
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.
