NOISEBOX®

A family of products that effectively and securely protects your meetings against eavesdropping and recording via mobile phones!

Very easy to use

Prevents eavesdropping

Charges phones

Keep your discussions private.

Any smartphone with a malicious app can be used for listening in on everything that its microphone can pick up. This is true even when the device is placed in sleep mode and even turned off. NoiseBox solves the problem and easily protects your meetings from eavesdropping. Place all the phones in the NoiseBox and activate it. If you like, you can connect the phones to the integrated USB ports for charging. In addition, some models can detect ringtones to prevent calls from being missed.

NoiseBox is a Marenius product that was developed in collaboration with the Swedish Armed Forces and Swedish Police to meet the need of a portable device that could protect against spying on mobile applications during interrogations and conversations of a confidential nature. Since 2012, the devices have been used both in Sweden and internationally. The NoiseBox exterior is extremely discreet and doesn’t stand out in even the most exclusive conference environments. It is available in a number of different solid wood materials, all handcrafted in Sweden with superb finish.

How does NoiseBox work?

NoiseBox has integrated speakers with specially developed electronics that produce completely random, wide-spectral acoustic noise. . This noise effectively blocks the microphone in phones or other audio-recording devices placed inside the NoiseBox. The camera function is effectively blocked by it being completely dark inside the box.
This eliminates the need for users to surrender their phones during confidential calls, and meetings can be held securely without the risk of interception via the devices placed inside the NoiseBox. If you like, the phones can also be charged while in the NoiseBox via either 2 or 4 USB ports inside the device.

What is NoiseBox used for?

NoiseBox’s unique design and functions creates an interception- and recording-safe environment, designed for high levels of privacy and demanding confidential use cases. These can be interrogation scenarios, interview situations or other cases where conversations are conducted and the risk of recording should be minimized, this without causing disturbances as the noise level outside the box is negligible.

How is NoiseBox used?

Place all devices to be protected in the NoiseBox.

Press the button inside the NoiseBox to activate it and, if you like, connect the phones to the integrated USB ports for charging.

Close the lid of the NoiseBox. Your meeting is now protected from eavesdropping.

When privacy is no longer needed, open the box and deactivate the NoiseBox device via the integrated button.

Guaranteed function tested by RISE

NoiseBox-S1® has also been tested by the Swedish Research Institute (RISE/SP).
After measurements, RISE/SP stated:

“Assuming a worst-case scenario with loud voice conversation/argumentation in a room of about 85 dBA (human shouting), there is an extremely low probability of recording or distinguishing what is said from inside the box when the masking noise is on and the box lid is closed. Note that normal conversations are at around 60-65 dBA.”

SNRuni32 is a parameter that can be matched against speech comprehension. The parameter is a result of research conducted by Bradley, J.S. and Gover, B.N.
The researchers found that a value of -16 dB or less is the threshold for comprehensibility. All NoiseBox® devices are below this value, and NoiseBox-S1® and S1+ have a value of -44 dB which provides a margin for eavesdropping of 28 dB.

Manipulation protection

NoiseBox is also available in versions with electronic manipulation protection that guarantees that no manipulation of the protective electronics in the NoiseBox can be carried out undetected. This manipulation protection provides the absolute highest level of security in the NoiseBox family. If attempts at manipulation are made, protection will be activated and the NoiseBox will emit an alarm signal. The NoiseBox can then only be restored by sending the device to Marenius for inspection. As of now, this feature is only included with NoiseBox models S1+.

If you want the absolute best

Any NoiseBox protects well against eavesdropping, but there is always one that has to be best. If you want maximum protection while keeping the sound on the outside to a minimum, there is a clear winner: NoiseBox S1+. With its unparalleled sound attenuation, bright LED on the exterior indicating that the NoiseBox is activated, along with integrated manipulation protection, this device provides maximum protection in any situation.

Handcrafted in Sweden

All wood NoiseBox enclosures are constructed in selected, rod-glued, FSC-certified wood by local cabinet makers.
This makes each NoiseBox a fine example of superb craftsmanship, with each exterior being unique.
