Sonify makes a hardware sound-masking system consisting of a base station and surface exciters that detect unwanted noise entering a room and mask it at the walls, windows, and ceiling using frequency-matched adaptive masking. Marketed to consumers for quieter sleep and living spaces, it processes audio locally and works offline, with an optional iOS/Android app and wake-light features.

Company profile
researched Sep 2026Sonify develops a consumer sound-masking system built around a base station and surface-mounted exciters. The base station's microphones listen to and analyze intruding noise such as traffic, barking dogs, footsteps from upstairs neighbors and car horns, and the exciters convert surfaces such as ceilings and walls into radiating speakers that play masking sound matched to the offending frequencies. The company states this approach masks noise at the point of entry and at lower volumes than conventional white-noise machines, and claims noise reduction of up to 80% regardless of listener position in the room.
The system is positioned for sleep and residential living spaces. It is described as adaptive over time, learning recurring noise patterns (for example, an upstairs neighbor waking at 5am) and adjusting masking proactively; the company cites an average of 50 additional minutes of sleep per night for users in New York City. The base station includes a wake light using Japanese Hypersun full-spectrum LEDs intended to support circadian rhythm, plus tactile buttons and a rotary control so that masking level and light can be adjusted without a phone. Installation is described as tool-free and taking about two minutes: attaching an exciter to a surface where noise enters, placing the base station, and pressing a button. Sound recordings are processed locally on the device and then deleted, and the mounting method is described as removing cleanly without damaging paint. Additional functions under development include guided meditation, sleep apnea tracking and voice-to-notepad.

▸Full profile — technology, go-to-market
Technology
The system pairs microphones in a base station with surface-mounted exciters that turn walls, windows and ceilings into sound-radiating surfaces. Incoming noise is analyzed so that masking audio is targeted to the specific frequencies of the intrusion, allowing masking at lower volume than broadband white noise. The system adapts in real time and learns recurring noise patterns to adjust masking proactively. Audio is processed locally on the device and recordings are deleted afterwards.
Go-to-market
The company runs a presale site collecting email reservations for launch invitations and early-bird pricing ahead of a product launch.
Consumers seeking quieter sleep and living environments, particularly apartment dwellers exposed to neighbor noise, footsteps and street noise in dense urban settings such as New York City.
