VoidSonic – Ultrasonic Microphone Blocking

Ultrasonic Protection Against Phone Recording

Keep Sensitive Conversations Private

VoidSonic is a compact and discreet privacy device designed to help protect conversations from smartphone microphone recording.

Using ultrasonic mixing interference technology, VoidSonic creates an acoustic environment around smartphone microphones that can interfere with their ability to capture clear, intelligible speech.

Simply place your smartphone on the VoidSonic dock. The device automatically detects the phone and activates its ultrasonic protection, allowing you to focus on the conversation without complicated settings or procedures.

Completely Quiet During Operation

VoidSonic is designed to operate without producing audible sound that would disturb the people or conversation around it.

When activated, the device generates ultrasonic audio outside the normal range of human hearing. The protection therefore works discreetly in the background without audible tones, buzzing, masking noise or other sounds that would interfere with the meeting.

People in the room can continue their conversation normally while VoidSonic operates.

This makes the device particularly suitable for professional environments where privacy protection needs to be effective without drawing attention to the technology itself.

Portable Privacy

One of VoidSonic’s key advantages is that it does not need to be permanently installed in a meeting room.

At approximately 300 grams and measuring 200 × 100 × 46 mm, VoidSonic is compact enough to move between offices, meeting rooms and other locations.

Take it with you whenever privacy matters.

It can be used in a boardroom in the morning, moved to a private office for a confidential meeting and taken to another location when required.

This makes VoidSonic particularly useful for organizations that do not have dedicated secure meeting facilities, as well as professionals who frequently work across different locations.

Its portable design means that privacy protection does not have to be tied to a particular room.

Discreet by Design

VoidSonic is designed to fit naturally into a professional meeting environment.

Its compact dock format allows a smartphone to be placed directly on the device, rather than requiring a large security installation or specialized room equipment.

Because the ultrasonic protection is inaudible during operation, VoidSonic does not introduce distracting sounds into the room. Participants can continue their conversation normally while the device operates discreetly in the background.

There are no complicated controls to manage during a meeting. Automatic activation and a visible operating-status indicator make the system straightforward to use without drawing unnecessary attention to the privacy process.

For confidential meetings, this means privacy protection can become part of the normal meeting setup rather than an intrusive security procedure.

What Makes VoidSonic Different?

VoidSonic combines three important characteristics in one privacy device: ultrasonic microphone interference, completely inaudible operation and portability.

Unlike audible sound-masking systems, VoidSonic does not require loud background noise or disruptive audio to create a privacy barrier.

Unlike conventional signal-blocking systems, it does not rely on disabling the phone’s cellular, WiFi or Bluetooth connectivity.

And unlike permanent room-based privacy installations, VoidSonic can travel with you.

The result is a compact privacy solution that can be placed directly into a meeting environment and operated discreetly while normal conversation continues.

Privacy That Travels With You

Confidential conversations do not always happen in secure rooms.

That is why VoidSonic is designed to be portable, discreet and simple to operate.

Take it wherever the conversation goes. Place it on the table, place the smartphone on the dock and let the device provide its ultrasonic interference while the meeting continues normally.

No audible masking noise. No complicated setup. No need to disconnect the phone from its wireless networks.

Just discreet ultrasonic protection for conversations that should remain private.
