Quell
Sound masking for Public sector
Citizen conversations stay confidential
Sensitive information at an open counter stays between you and the person in front of you.
Quell Masker at an open service counter
The problem
No noise distracts like a conversation you can understand.
Citizen office, social services, registry: sensitive information given across open counters, often within earshot of the next person.

Service hall: sensitive information within earshot of the next person
- Supports your GDPR obligations
- Built for open counter areas
- No intervention in the building fabric
What happens in the room
- Speech from the next conversation
- Quell's masking signal
- What arrives: a calm room
Quell lifts the baseline exactly where speech becomes intelligible — and no further. The room does not get louder; the words stop making sense.
The devices
Two devices, one job.

Quell Masker
Generates the masking signal and radiates it through the surface it stands on. A closed housing with no speaker grille — it disappears into the room.

Quell microphone satellite
Measures the level where it matters and reports it to the masker. It analyses frequencies and measures loudness — it records nothing.
Adaptive
When the room gets louder, Quell follows. When it quietens, Quell steps back. You set the volume; the device only moves within your range.
Mesh
Up to 20 devices form their own radio network. Set it up once — the floor stays in step, even when nobody adjusts anything.
Specifications
- Powered over USB-C
- Bluetooth for the app, its own radio network for the mesh
- Place it, plug it in, done — no construction, no cabling
One masker per counter zone; the mesh keeps the level even across the whole hall, with nobody adjusting anything.
The app
Everything in hand, without tools.

- Volume and mute Fine steps, or jump straight to a preset.
- Soundscape and equaliser Change the sound and shape it to the room across eight bands.
- Adaptive mode Switch the automation on or off and set how far it may move.
- Firmware updates Install new device software straight over Bluetooth.
- Guided setup A wizard walks you through single device, mesh and Privacy-Glass.
- Four languages The app speaks German, English, French and Spanish.
The app includes a demo mode: you can try it in full before a device ever reaches you.
Let's talk about your space.
Tell us where it is too loud or too open. We will come back with a concrete assessment — no sales loop.
Quell analyses speech frequencies and measures the level. It records nothing and transmits no conversations.
