Microphone Nullification for Restricted Areas
Microphones, including phones, can pick up speech in restricted areas, including accidental calls.
Solutions
How we solve it
Portable or permanent nullification for offices, rooftops, restrooms, and trading floors, aimed at everyday device mics and human-hearing-range speech pickup.
What you are dealing with
Phones in pockets still pick up restricted conversations. Accidental pocket-dials are a recurring fear. Policy says no recording but there is no technical control in the room.
Our approach
We deploy portable or permanent nullification aimed at everyday device microphones and human-hearing-range pickup in offices, trading floors, rooftops, and restrooms. Scope covers where nullification fits alongside policy and area design, not as a substitute for room-level speech privacy where that is the primary risk.
What done looks like
Device microphones in the treated zone cannot reliably capture intelligible speech. Staff understand where nullification applies and where custody or room privacy still matters. Compliance can point to a technical control, not policy alone.
